     feh — image viewer and cataloguer


     feh [options] files or directories or URLs ...


     This manual documents feh 2.9.3

     Compile-time switches: libcurl support enabled, Xinerama support enabled, builtin EXIF
     support enabled


     feh is a mode-based image viewer.  It is especially aimed at command line users who need a
     fast image viewer without huge GUI dependencies, though it can also be started by
     (graphical) file managers to view an image.

     feh supports filelists, various image sorting modes, image captions, HTTP and more.
     Configurable keyboard shortcuts are used to control it; the mouse is also supported, but
     only required for very few actions.

     feh can also be used as wallpaper setter.

     A little note about EXIF support: The recommended way to display EXIF data is using exiv2 /
     exifgrep via --info (see the USAGE EXAMPLES section).  However, if you compile feh with
     exif=1, you can also display it directly.


     feh is based on various modes, which are selected at startup by command line options.

     Slideshow mode is the default.  It opens one window and displays the first image in it, the
     keyboard and mouse can be used to change slides (images).  In slideshow mode, images can be
     deleted either from the filelist or from the disk, the new filelist can then be saved to the
     disk and reopened at a later time.  An image can also be read from stdin via "feh -".

     Montage mode forms a montage from the filelist.  The resulting image can be viewed or saved,
     and its size can be limited by height, width or both.

     Index mode forms an index print from the filelist.  Image thumbnails are shown along with
     the filename, filesize and pixel size, printed using a truetype font of your choice.  The
     resulting image can be viewed or saved, and its size can be limited by height, width or

     Thumbnail mode is like index mode, but the mini-images are clickable and open the selected
     image in a new window.

     Multiwindow mode shows images in multiple windows, instead of as a slideshow in one window.
     Don't use with a large filelist ;)

     List mode doesn't display images.  Outputs an ls - style listing of the files in the
     filelist, including image info such as size, pixels, type, etc.  Customlist mode will
     display whatever image info you want, in the format you choose.

     feh can also list either all the loadable files in a filelist or all the unloadable files.
     Useful for preening a directory.


     feh can open any format supported by Imlib2, most notably jpeg and png.  If the convert
     binary (supplied by ImageMagick) is available, it also has limited support for many other
     filetypes, such as svg, xcf and otf. Use --magick-timeout num with a non-negative value to
     enable it.  For animated images, only the first frame is shown.


     -A, --action [flag]action
             Specify a shell command as an action to perform on the image.  In slideshow or
             multiwindow mode, the action will be run when the action_0 key is pressed, in list
             mode, it will be run for each file.  In loadable/unloadable mode, it will be run for
             each loadable/unloadable file, respectively.

             If flag is ";", feh will reload the current image instead of switching to the next
             one after executing the action.

             The action will be executed by /bin/sh.  Use format specifiers to refer to image
             info.  See FORMAT SPECIFIERS for examples.  E.g.  "feh -A mv ~/images/%n *".  In
             slideshow mode, the next image will be shown after running the action, in
             multiwindow mode, the window will be closed.

     --action1 .. --action9
             Extra actions which can be set and triggered using the appropriate number key.

     -Z, --auto-zoom
             Zoom pictures to screen size in fullscreen / fixed geometry mode.

     -x, --borderless
             Create borderless windows.

     -P, --cache-thumbnails
             Enable thumbnail caching in ~/.thumbnails.  Only works with thumbnails <= 256x256

     -K, --caption-path path
             Path to directory containing image captions.  This turns on caption viewing, and if
             captions are found in path, which is relative to the directory of each image, they
             are overlayed on the displayed image.  E.g. with caption path "captions/", and
             viewing image "images/foo.jpg", the caption will be looked for in

     -L, --customlist format
             Don't display images, print image info according to format instead.  See FORMAT

             Exit feh after one loop through the slideshow.

     -G, --draw-actions
             Draw the defined actions and what they do at the top-left of the image.

             (only if compiled with exif=1) display some EXIF information in the bottom left
             corner, similar to using --info with exiv2 / exifgrep .

     -d, --draw-filename
             Draw the filename at the top-left of the image.

             Show overlay texts (as created by --draw-filename et al) on a semi-transparent
             background to improve their readability

     -f, --filelist file
             This option is similar to the playlists used by music software.  If file exists, it
             will be read for a list of files to load, in the order they appear.  The format is a
             list of image filenames, absolute or relative to the current directory, one filename
             per line.

             If file doesn't exist, it will be created from the internal filelist at the end of a
             viewing session.  This is best used to store the results of complex sorts (-Spixels
             for example) for later viewing.

             Any changes to the internal filelist (such as deleting a file or it being pruned for
             being unloadable) will be saved to file when feh exits.  You can add files to
             filelists by specifying them on the command line when also specifying the list.

             If file is "-", feh will read the filelist from its standard input.

     -e, --font font
             Set global font.  Should be a truetype font, resident in the current directory or
             the font directory, and should be defined in the form fontname/points, like

     -C, --fontpath path
             Specify path as extra directory in which to search for fonts; can be used multiple
             times to add multiple paths.

             Disable antialiasing for zooming, background setting etc.

     -I, --fullindex
             Same as index mode, but with additional information below the thumbnails.  Works
             just like "feh --index --index-info "%n\n%S\n%wx%h"".  Enables MONTAGE MODE OPTIONS.

             Note: This option needs to load all images to calculate the dimensions of the feh
             window, so when using it with many files it will take a while before a feh window is
             visible.  Use --preload to get a progress bar.

     -F, --fullscreen
             Make the window fullscreen.  Note that in this mode, large images will always be
             scaled down to fit the screen, --zoom zoom only affects smaller images and never
             scales larger than necessary to fit the screen size. The only exception is a zoom of
             100, in which case images will always be shown at 100% zoom, no matter their

     -g, --geometry [width x height] [+ x + y]
             Limit (and don't change) the window size.  Takes an X-style geometry string like
             640x480 with optional +x+y window offset.  Note that larger images will be zoomed
             out to fit, but you can see them at 1:1 by clicking the zoom button.  Note that this
             option does not enforce the geometry, changing it by a tiling WM or manually is
             still possible.

     -Y, --hide-pointer
             Hide the pointer (useful for slideshows).

     -B, --image-bg style
             Use style as background for transparent image parts and the like.  Accepted values:
             checks (default), white, black.

     -i, --index
             Enable Index mode.  Index mode is similar to montage mode, and accepts the same
             options.  It creates an index print of thumbnails, printing the image name beneath
             each thumbnail.  Index mode enables certain other options, see INDEX MODE OPTIONS
             and MONTAGE MODE OPTIONS.

     --index-info format
             Show image information based on format below thumbnails in index / thumbnail mode.
             See FORMAT SPECIFIERS.  May contain newlines.

             Note: If you specify image-related formats (such as %w or %s), feh needs to load all
             images to calculate the dimensions of its own window.  So when using them with many
             files, it will take a while before a feh window becomes visible.  Use --preload to
             get a progress bar.

     --info commandline
             Execute commandline and display its output in the bottom left corner of the image.
             Can be used to display e.g. image dimensions or EXIF information.  Supports FORMAT

     -k, --keep-http
             When viewing files using HTTP, feh normally deletes the local copies after viewing,
             or, if caching, on exit.  This option prevents this so that you get to keep the
             local copies.  They will be in /tmp with "feh" in the name.

             When switching images, keep zoom and viewport settings (zoom level and X, Y offsets)

     -l, --list
             Don't display images.  Analyze them and display an ls(1) - style listing.  Useful in
             scripts to hunt out images of a certain size/resolution/type etc.

     -U, --loadable
             Don't display images.  Just print out their names if imlib2 can successfully load
             them.  Returns false if at least one image failed to load.

     --magick-timeout timeout
             Stop trying to convert unloadable files after timeout seconds. A negative value
             disables covert / magick support altogether, a value of zero causes feh to try
             indefinitely. By default, magick support is disabled.

     --max-dimension width x height
             Only show images with width <= width and height <= height.  If you only care about
             one parameter, set the other to either something large or -1.

     -M, --menu-font font
             Use font (truetype, with size, like "yudit/12") as menu font.

     --min-dimension width x height
             Only show images with width >= width and height >= height.  If you only care about
             one parameter, set the other to 0.

     -m, --montage
             Enable montage mode.  Montage mode creates a new image consisting of a grid of
             thumbnails of the images in the filelist.  When montage mode is selected, certain
             other options become available.  See MONTAGE MODE OPTIONS.

     -w, --multiwindow
             Disable slideshow mode.  With this setting, instead of opening multiple files in
             slideshow mode, multiple windows will be opened; one per file.

             Don't jump to the first image after resorting the filelist.

     -N, --no-menus
             Don't load or show any menus.

             By default, window sizes are limited to the screen size.  With this option, windows
             will have the size of the image inside them.  Note that they may become very large
             this way, making them unmanageable in certain window managers.

             Disable Xinerama support.  Only makes sense when you have Xinerama support compiled

     -j, --output-dir directory
             Save files to directory (only useful with -k)

     -p, --preload
             Preload images.  This doesn't mean hold them in RAM, it means run through them and
             eliminate unloadable images first.  Otherwise they will be removed as you flick
             through.  This also analyses the images to get data for use in sorting, such as
             pixel size, type etc.  A preload run will be automatically performed if you specify
             one of these sort modes.

     -q, --quiet
             Don't report non-fatal errors for failed loads.  Verbose and quiet modes are not
             mutually exclusive, the first controls informational messages, the second only

     -z, --randomize
             When viewing multiple files in a slideshow, randomize the file list before

     -r, --recursive
             Recursively expand any directories in the commandline arguments to the content of
             those directories, all the way down to the bottom level.

     -R, --reload int
             Reload filelist and current image after int seconds.  Useful for viewing HTTP
             webcams or frequently changing directories.  (Note that the filelist reloading is
             still experimental.)

             If an image is removed, feh will either show the next one or quit.  However, if an
             image still exists, but can no longer be loaded, feh will continue to try loading

     -n, --reverse
             Reverse the sort order.  Use this to invert the order of the filelist.  E.g. to sort
             in reverse width order, use -nSwidth.

     -., --scale-down
             When not in fullscreen: Scale images to screen size if they are too big.

             In tiling environments, this also causes the image to be centered in the window.

     -D, --slideshow-delay float
             For slideshow mode, wait float seconds between automatically changing slides.
             Useful for presentations.  Specify a negative number to set the delay (which will
             then be float * (-1)), but start feh in paused mode.

     -S, --sort sort_type
             The file list may be sorted according to image parameters.  Allowed sort types are:
             name, filename, mtime, width, height, pixels, size, format.  For sort modes other
             than name, filename, or mtime, a preload run will be necessary, causing a delay
             proportional to the number of images in the list.

             The mtime sort mode sorts images by most recently modified. To sort by oldest first,
             reverse the filelist with --reverse.

     -|, --start-at filename
             Start the filelist at filename.  See USAGE EXAMPLES.

     -T, --theme theme
             Load options from config file with name theme - see THEMES CONFIG SYNTAX for more
             info.  Note that commandline options always override theme options.  The theme can
             also be set via the program name (e.g. with symlinks), so by default feh will look
             for a "feh" theme.

     -t, --thumbnails
             Same as Index mode, but the thumbnails are clickable image launchers.  Note that
             --fullscreen and --scale-down do not affect the thumbnail window. They do, however,
             work for image windows launched from thumbnail mode.  Also supports MONTAGE MODE

     -~, --thumb-title string
             Set title for windows opened from thumbnail mode.  See also FORMAT SPECIFIERS.

     -^, --title title
             Set window title.  Applies to all windows except those opened from thumbnail mode.
             See FORMAT SPECIFIERS.

     -u, --unloadable
             Don't display images.  Just print out their names if imlib2 can NOT successfully
             load them.  Returns false if at least one image was loadable.

     -V, --verbose
             output useful information, progress bars, etc.

     -v, --version
             output version information and exit.

     --zoom percent | max | fill
             Zoom images by percent when in full screen mode or when window geometry is fixed.
             When combined with --auto-zoom, zooming will be limited to the specified percent.
             Specifying max is like setting --auto-zoom, using fill makes feh zoom the image like
             the --bg-fill mode.


     These additional options can be used for index, montage and (partially) thumbnail mode.

     -a, --alpha int
             When drawing thumbnails onto the background, set their transparency level to int (0
             - 255).

     -b, --bg file | trans
             Use file as background for your montage.  With this option specified, the montage
             size will default to the size of file if no size restrictions were specified.
             Alternatively, if file is "trans", the background will be made transparent.

     -X, --ignore-aspect
             By default, the montage thumbnails will retain their aspect ratios, while fitting
             into thumb-width/-height.  This options forces them to be the size set by
             --thumb-width and --thumb-height.  This will prevent any empty space in the final

     -H, --limit-height pixels
             Limit the height of the montage.

     -W, --limit-width pixels
             Limit the width of the montage, defaults to 800 pixels.

             If both --limit-width and --limit-height are specified, the montage will be exactly
             width x height pixels in dimensions.

     -o, --output file
             Save the created montage to file.

     -O, --output-only file
             Just save the created montage to file without displaying it.

     -s, --stretch
             Normally, if an image is smaller than the specified thumbnail size, it will not be
             enlarged.  If this option is set, the image will be scaled up to fit the thumbnail
             size.  Aspect ratio will be maintained unless --ignore-aspect is specified.

     -E, --thumb-height pixels
             Set thumbnail height.

     -y, --thumb-width pixels
             Set thumbnail width.

     -J, --thumb-redraw n
             Only relevant for --thumbnails: Redraw thumbnail window every n images.  In feh <=
             1.5, the thumbnail image used to be redrawn after every computed thumbnail (so, it
             updated immediately).  However, since the redrawing takes quite long (especially for
             thumbnail mode on a large filelist), this turned out to be a major performance
             penalty.  As a workaround, the thumbnail image is redrawn every 10th image now by
             default. Set n = 1 to get the old behaviour, n = 0 will only redraw once all
             thumbnails are loaded.


     -@, --title-font font
             Set font to print a title on the index, if no font is specified, no title will be


     feh can also be used as a background setter.  Unless you pass the --no-fehbg option, it will
     store the command line necessary to set the background in ~/.fehbg, so to have your
     background restored every time you start X, you can add "eval $(cat ~/.fehbg)" to your X
     startup script (like ~/.xinitrc).

     Note that all options except --bg-tile support Xinerama.  For instance, if you have multiple
     screens connected and use e.g.  --bg-center, feh will center the image on each screen.  You
     may even specify more than one file, in that case, the first file is set on screen 0, the
     second on screen 1, and so on.

     Use --no-xinerama to treat the whole X display as one screen when setting wallpapers.

             Center the file on the background.  If it is too small, it will be surrounded by a
             black border

             Like --bg-scale, but preserves aspect ratio by zooming the image until it fits.
             Either a horizontal or a vertical part of the image will be cut off

             Like --bg-fill, but scale the image to the maximum size that fits the screen with
             black borders on one side.

             Fit the file into the background without repeating it, cutting off stuff or using
             borders.  But the aspect ratio is not preserved either

             Tile (repeat) the image in case it is too small for the screen

             Do not write a ~/.fehbg file


     %f      Image path/filename

     %F      Escaped image path/filename (for use in shell commands)

     %h      Image height

     %l      Total number of files in filelist

     %L      Temporary copy of filelist. Multiple uses of %L within the same format string will
             return the same copy.

     %m      Current mode

     %n      Image name

     %N      Escaped image name

     %o      x,y offset of top-left image corner to window corner in pixels

     %p      Number of image pixels

     %P      Number of image pixels (kilopixels / megapixels)

     %r      Image rotation. A half right turn equals pi.

     %s      Image size in bytes

     %S      Human-readable image size (kB / MB)

     %t      Image format

     %u      Number of current file

     %w      Image width

     %v      feh version
     Process ID

     %z      current image zoom


     feh has three config files: themes for theme definitions, keys for key bindings and buttons
     for mouse button bindings.  It will try to read them from $XDG_CONFIG_HOME/feh/, which (when
     XDG_CONFIG_HOME is unset) defaults to ~/.config/feh/.  If the files are not found in that
     directory, it will also try /etc/feh/.

     All config files treat lines starting with a "#" character as comments.  Note that mid-line
     comments are not supported.


     .config/feh/themes allows the naming of option groups, called themes.

     It takes entries of the form "theme options ...", where theme is the name of the entry and
     options are the options which will be applied when the theme is used.

     An example entry would be "imagemap -rVq --thumb-width 40 --thumb-height 30".

     You can use this theme in two ways.  Either call "feh -Timagemap *.jpg" or create a symbolic
     link to feh with the name of the theme you want it to use.  So from the example above: "ln
     -s `which feh ` ~/bin/imagemap".  Now just run "imagemap *.jpg" to use these options.

     Note that you can split a theme over several lines by placing a backslash at the end of a
     line, like in the shell.

     You can combine these themes with commandline options.


     .config/feh/keys defines key bindings.  It has entries of the form "action [key1 [key2

     Each key is an X11 keysym name as shown by xev(1), like "Delete".  It may optionally start
     with modifiers for things like Control, in which case key looks like mod-keysym (for example
     "C-Delete" for Ctrl+Delete or "C-1-Delete" for Ctrl+Alt+Delete)

     Available modifiers are C for Control, S for Shift and 1, 4 for Mod1 and Mod4.  To match an
     uppercase letter like "S" instead of "s", the Shift modifier is not required.

     Specifying an action without any keys unbinds it (i.e. the default bindings are removed).

     Note: Do not use the same keybinding for multiple actions.  feh does not check for
     conflicting bindings, so their behaviour is undefined.  Either unbind the unwanted action,
     or bind it to another unused key.  The order in which you bind / unbind does not matter,

     For a list of the action names, see KEYS.


     In an image window, the following keys may be used (The strings in [square brackets] are the
     config action names):

     a [toggle_actions]
             Toggle actions display (see --draw-actions)

     A [toggle_aliasing]
             Enable/Disable anti-aliasing

     c [toggle_caption]
             Caption entry mode.  If --caption-path has been specified, then this enables caption
             editing.  The caption at the bottom of the screen will turn yellow and can be
             edited.  Hit return to confirm and save the caption, or escape to cancel editing.
             Note that you can insert an actual newline into the caption using ⟨CTRL+return⟩.

     d [toggle_filenames]
             Toggle filename display (see --draw-filename)

     e [toggle_exif]
             (only if compiled with exif=1) Toggle EXIF tag display

     f [save_filelist]
             Save the current filelist as "feh_PID_ID_filelist"

     h [toggle_pause]
             Pause/Continue the slideshow.  When it is paused, it will not automatically change
             slides based on --slideshow-delay.

     i [toggle_info]
             Toggle info display (see --info)

     k [toggle_keep_vp]
             Toggle zoom and viewport keeping. When enabled, feh will keep zoom and X, Y offset
             when switching images.

     m [toggle_menu]
             Show menu.  Use the arrow keys and return to select items, ⟨escape⟩ to close the

     n, ⟨Space⟩, ⟨Right⟩ [next_img]
             Show next image

     o [toggle_pointer]
             Toggle pointer visibility

     p, ⟨Backspace⟩, ⟨Left⟩ [prev_img]
             Show previous image

     q, ⟨Escape⟩ [quit]
             Quit feh

     r [reload_image]
             Reload current image.  Useful for webcams

     s [save_image]
             Save the current image as "feh_PID_ID_FILENAME"

     v [toggle_fullscreen]
             Toggle fullscreen

     w [size_to_image]
             Change window size to fit current image size

     x [close]
             Close current window

     z [jump_random]
             Jump to a random position in the current filelist

     <, > [orient_3, orient_1]
             In place editing - rotate the images 90 degrees (counter)clockwise.  The rotation is
             lossless, but may create artifacts in some image corners when used with JPEG images.
             Rotating in the reverse direction will make them go away.  See jpegtran(1) for more
             about lossless JPEG rotation.  Note: jpegtran does not update EXIF orientation tags.
             However, feh assumes that you use the feature to normalize image orientation and
             want it to be displayed this way everywhere. After every rotation, it will
             unconditionally set the EXIF orientation to 1 ("0,0 is top left").  Should you need
             to reverse this, see jpegexiforient(1).

     _ [flip]
             In place editing - vertical flip

     | [mirror]
             In place editing - horizontal flip.  Again, see jpegtran(1) for more information.

     0 .. 9 [action_0 .. action_9]
             Execute the corresponding action (0 = --action, 1 = --action1 etc.)

     ⟨Return⟩ [action_0]
             Run the command defined by --action

     ⟨home⟩ [jump_first]
             Show first image

     ⟨end⟩ [jump_last]
             Show last image

     ⟨page up⟩ [jump_fwd]
             Go forward ~5% of the filelist

     ⟨page down⟩ [jump_back]
             Go backward ~5% of the filelist

     + [reload_plus]
             Increase reload delay by 1 second

     - [reload_minus]
             Decrease reload delay by 1 second

     ⟨delete⟩ [remove]
             Remove current file from filelist

     ⟨CTRL+delete⟩ [delete]
             Remove current file from filelist and delete it

     ⟨keypad left⟩, ⟨Ctrl+Left⟩ [scroll_left]

             Scroll up

     ⟨keypad down⟩, ⟨Ctrl+Down⟩ [scroll_down]
             Scroll down.  Note that the scroll keys work without anti-aliasing for performance
             reasons, hit the render key after scrolling to antialias the image.

     ⟨Alt+Left [scroll_left_page]⟩
             Scroll to the left by one page

     ⟨Alt+Right [scroll_right_page]⟩
             Scroll to the right by one page

     ⟨Alt+Up [scroll_up_page]⟩
             Scroll up by one page

     ⟨Alt+Down [scroll_down_page]⟩
             Scroll down by one page

     R, ⟨keypad begin⟩ [render]
             Antialias the image

     ⟨keypad +⟩, ⟨Up⟩ [zoom_in]
             Zoom in

             Highlight parent menu item

     ⟨Right⟩ [menu_child]
             Highlight child menu item

     ⟨Return⟩, ⟨Space⟩ [menu_select]
             Select highlighted menu item


     .config/feh/buttons.  This works like the keys config file: the entries are of the form
     "action [binding]".

     Each binding is a button name.  It may optionally start with modifiers for things like
     Control, in which case binding looks like mod-button (for example C-1 for Ctrl + Left

     Note: Do not use the same button for multiple actions.  feh does not check for conflicting
     bindings, so their behaviour is undefined.  Either unbind the unwanted action, or bind it to
     another unused button.  The order in which you bind / unbind does not matter, though.

     For the available modifiers, see KEYS CONFIGURATION SYNTAX.

     In an image window, the following buttons may be used (The strings in [square brackets] are
     the config action names):

             Reload current image

     1 ⟨left mouse button⟩ [pan]
             pan the current image

     2 ⟨middle mouse button⟩ [zoom]
             Zoom the current image

     3 ⟨right mouse button⟩ [menu]
             Toggle menu

     4 ⟨mousewheel down⟩ [prev]
             Show previous image

     5 ⟨mousewheel up⟩ [next]
             Show next image

     Ctrl+1 [blur]
             Blur current image

     Ctrl+2 [rotate]
             Rotate current image

     unbound [zoom_in]
             Zoom in

     unbound [zoom_out]
             Zoom out


     Default Bindings: When viewing an image, mouse button 1 pans the image (moves it around) or,
     when only clicked, moves to the next image (slideshow mode only).  Quick drags with less
     than 2px of movement per axis will be treated as clicks to aid graphics tablet users.  Mouse
     button 2 zooms (click and drag left->right to zoom in, right->left to zoom out, click once
     to restore zoom to 100%) and mouse button 3 opens the menu.

     CTRL+Button 1 blurs or sharpens the image (drag left to blur, right to sharpen); CTRL+Button
     2 rotates the image around the center point.

     A note about pan and zoom modes: In pan mode, if you reach a window border but haven't yet
     panned to the end of the image, feh will warp your cursor to the opposite border so you can
     continue panning.

     When clicking the zoom button and immediately releasing it, the image will be back at 100%
     zoom.  When clicking it and moving the mouse while holding the button down, the zoom will be
     continued at the previous zoom level.  The zoom will always happen so that the pixel on
     which you entered the zoom mode remains stationary.  So, to enlarge a specific part of an
     image, click the zoom button on that part.


     In slideshow mode, feh handles the following signals:

             Switch to next image

             Switch to previous image


     Here are some examples of useful option combinations. See also:

     feh /opt/images
             Show all images in /opt/images

     feh -r /opt/images
             Recursively show all images found in /opt/images and subdirectories

     feh -rSfilename /opt/images
             Same as above, but sort by filename. By default, feh will show files in the order it
             finds them on the hard disk, which is usually somewhat random.

     feh -t -Sfilename -E 128 -y 128 -W 1024 /opt/images
             Show 128x128 pixel thumbnails, limit window width to 1024 pixels.

     feh -t -Sfilename -E 128 -y 128 -W 1024 -P -C /usr/share/fonts/truetype/ttf-dejavu/ -e
             DejaVuSans/8 /opt/images
             Same as above, but enable thumbnail caching in ~/.thumbnails and use a smaller font.

     feh -irFarial/14 -O index.jpg /opt/images
             Make an index print of /opt/images and all directories below it, using 14 point
             Arial to write the image info under each thumbnail.  Save the image as index.jpg and
             don't display it, just exit.  Note that this even works without a running X server

     feh --unloadable -r /opt/images
             Print all unloadable images in /opt/images, recursively

     feh -f by_width -S width --reverse --list .
             Write a list of all images in the directory to by_width, sorted by width (widest
             images first)

     feh -w /opt/images/holidays
             Open each image in /opt/images/holidays in its own window

     feh -FD5 -Sname /opt/images/presentation
             Show the images in .../presentation, sorted by name, in fullscreen, automatically
             change to the next image after 5 seconds

     feh -rSwidth -A "mv %F ~/images/%N" /opt/images
             View all images in /opt/images and below, sorted by width, move an image to
             ~/image/image_name when enter is pressed

     feh --start-at ./foo.jpg .
             View all images in the current directory, starting with foo.jpg.  All other images
             are still in the slideshow and can be viewed normally

     feh --start-at foo.jpg *
             Same as above

     feh --info "exifgrep '(Model|DateTimeOriginal|FNumber|ISO|Flash)' %F | cut -d . -f 4-" .
             Show some EXIF information, extracted by exifprobe/exifgrep

     feh --action 'rm %F' -rl --max-dim 1000x800
             Resursively remove all images with dimensions below or equal to 1000x800 pixels from
             the current directory.


     feh was created with a floating window layout in mind.  However, as of 2.0.1, it has limited
     support for tiling window managers.

     Specifically, the --scale-down and --auto-zoom options will detect a tiling environment and
     scale the image up / down to the current window size.  Unfortunately, this causes every
     image to be rendered twice: First in a normal fashion, and then (after noticing that the
     window is being tiled) again with the correct zoom level.

     This is a known bug and will hopefully get fixed some time. For now, it can be avoided by
     using --geometry 500x500 (or any other geometry).  This will have the same behaviour as
     --scale-down, but without the flickering.


     feh requires the jpegtran and jpegexiforient binaries (usually distributed in
     "libjpeg-progs" or similar) for lossless rotation.

     To view images from URLs such as http://, you need feh compiled with libcurl support
     (enabled by default).  See the VERSION section.


     Thumbnail mode is somewhat inefficient, and because of that not nearly as fast as it could

     --scale-down does not take window decorations into account and may therefore make the window
     slightly too large.

     If you find a bug, please report it to ⟨⟩ or via
     ⟨⟩.  You are also welcome to direct any feh-related
     comments/questions/... to #feh on

     Please include the feh version ⟨the output of "feh --version"⟩, steps to reproduce the bug
     and, if necessary, images to reproduce it.


     Plans for the following releases:
     ·   Make zoom options more intuitive
