NAME

       nano - Nano's ANOther editor, an enhanced free Pico clone

SYNOPSIS

       nano [options] [[+line[,column]] file]...

DESCRIPTION

       nano  is  a  small  and friendly editor.  It copies the look and feel of Pico, but is free
       software, and implements several features that  Pico  lacks,  such  as:  opening  multiple
       files,  scrolling  per line, undo/redo, syntax coloring, line numbering, and soft-wrapping
       overlong lines.

       When giving a filename on the command line, the cursor can be put on a  specific  line  by
       adding  the  line  number with a plus sign (+) before the filename, and even in a specific
       column by adding it with a comma.

       As a special case: if instead of a filename a dash (-) is given, nano will read data  from
       standard input.

EDITING

       Entering text and moving around in a file is straightforward: typing the letters and using
       the normal cursor movement keys.  Commands are entered by using the Control  (^)  and  the
       Alt  or  Meta (M-) keys.  Typing ^K deletes the current line and puts it in the cutbuffer.
       Consecutive ^Ks will put all deleted lines together in the cutbuffer.  Any cursor movement
       or  executing  any  other command will cause the next ^K to overwrite the cutbuffer.  A ^U
       will paste the current contents of the cutbuffer at the current cursor position.

       When a more precise piece of text needs to be cut or copied, one can mark its  start  with
       ^6,  move  the cursor to its end (the marked text will be highlighted), and then use ^K to
       cut it, or M-6 to copy it to the cutbuffer.  One can also save the marked text to  a  file
       with ^O, or spell check it with ^T.

       On  some  terminals, text can be selected also by holding down Shift while using the arrow
       keys.  Holding down the Ctrl or Alt key too will increase the stride.  Any cursor movement
       without Shift being held will cancel such a selection.

       The  two lines at the bottom of the screen show some important commands; the built-in help
       (^G) lists all the available ones.  The default key bindings can be changed via  a  nanorc
       file -- see nanorc(5).

OPTIONS

       -A, --smarthome
              Make the Home key smarter.  When Home is pressed anywhere but at the very beginning
              of non-whitespace characters on a line, the cursor  will  jump  to  that  beginning
              (either forwards or backwards).  If the cursor is already at that position, it will
              jump to the true beginning of the line.

       -B, --backup
              When saving a file, back up the previous version of it, using the current  filename
              suffixed with a tilde (~).

       -C directory, --backupdir=directory
              Make  and  keep not just one backup file, but make and keep a uniquely numbered one
              every time a file is saved -- when backups are enabled (-B).  The uniquely numbered
              files are stored in the specified directory.

       -D, --boldtext
              Use bold text instead of reverse video text.

       -E, --tabstospaces
              Convert typed tabs to spaces.

       -F, --multibuffer
              Read a file into a new buffer by default.

       -G, --locking
              Use vim-style file locking when editing files.

       -H, --historylog
              Save the last hundred search strings and replacement strings and executed commands,
              so they can be easily reused in later sessions.

       -I, --ignorercfiles
              Don't look at the system's nanorc nor at the user's nanorc.

       -K, --rebindkeypad
              Interpret the numeric keypad keys so that they all work properly.  You should  only
              need  to  use  this option if they don't, as mouse support won't work properly with
              this option enabled.

       -L, --nonewlines
              Don't automatically add a newline when a file does not end with one.

       -M, --trimblanks
              Snip trailing whitespace from the wrapped line when automatic hard-wrapping  occurs
              or when text is justified.

       -N, --noconvert
              Disable automatic conversion of files from DOS/Mac format.

       -O, --morespace
              Use the blank line below the title bar as extra editing space.

       -P, --positionlog
              For the 200 most recent files, log the last position of the cursor, and place it at
              that position again upon reopening such a file.

       -Q "regex", --quotestr="regex"
              Set the regular expression for matching the quoting part of a line.  This  is  used
              when  justifying.   The  default  value  is "^([ \t]*([#:>|}]|//))+".  Note that \t
              stands for an actual Tab.

       -R, --restricted
              Restricted mode: don't read or write to any file not specified on the command line.
              This  means: don't read or write history files; don't allow suspending; don't allow
              spell checking; don't allow a file to be appended to, prepended to, or saved  under
              a  different  name  if it already has one; and don't make backup files.  Restricted
              mode can also be activated by invoking nano with any name beginning with 'r'  (e.g.
              "rnano").

       -S, --smooth
              Use smooth scrolling: text will scroll line-by-line, instead of the usual chunk-by-
              chunk behavior.

       -T number, --tabsize=number
              Set the size (width) of a tab to number columns.   The  value  of  number  must  be
              greater than 0.  The default value is 8.

       -U, --quickblank
              Do  quick status-bar blanking: status-bar messages will disappear after 1 keystroke
              instead of 25.  Note that option -c (--constantshow) overrides this.

       -V, --version
              Show the current version number and exit.

       -W, --wordbounds
              Detect word boundaries differently by treating punctuation characters as part of  a
              word.

       -X "characters", --wordchars="characters"
              Specify  which  other  characters  (besides the normal alphanumeric ones) should be
              considered as part of a word.  This overrides option -W (--wordbounds).

       -Y name, --syntax=name
              Specify the name of the syntax highlighting to use from among the ones  defined  in
              the nanorc files.

       -Z, --zap
              Let  an unmodified Backspace or Delete erase the marked region (instead of a single
              character, and without affecting the cutbuffer).

       -a, --atblanks
              When doing soft line wrapping, wrap lines at whitespace instead of  always  at  the
              edge of the screen.

       -c, --constantshow
              Constantly  show  the  cursor position on the status bar.  Note that this overrides
              option -U (--quickblank).

       -d, --rebinddelete
              Interpret the Delete key  differently  so  that  both  Backspace  and  Delete  work
              properly.  You should only need to use this option if Backspace acts like Delete on
              your system.

       -g, --showcursor
              Make the cursor visible in the file browser (putting it on  the  highlighted  item)
              and in the help viewer.  Useful for braille users and people with poor vision.

       -h, --help
              Show a summary of the available command-line options and exit.

       -i, --autoindent
              Automatically  indent a newly created line to the same number of tabs and/or spaces
              as the previous line (or as the next line if the previous line is the beginning  of
              a paragraph).

       -k, --cutfromcursor
              Make  the  'Cut Text' command (normally ^K) cut from the current cursor position to
              the end of the line, instead of cutting the entire line.

       -l, --linenumbers
              Display line numbers to the left of the text area.

       -m, --mouse
              Enable mouse support, if available for your system.  When enabled, mouse clicks can
              be  used  to  place  the  cursor,  set  the mark (with a double click), and execute
              shortcuts.  The mouse will work in the X Window System, and on the console when gpm
              is  running.  Text can still be selected through dragging by holding down the Shift
              key.

       -n, --noread
              Treat any name given on the command line as a new file.  This allows nano to  write
              to  named pipes: it will start with a blank buffer, and will write to the pipe when
              the user saves the "file".  This way nano can be used as an editor  in  combination
              with for instance gpg without having to write sensitive data to disk first.

       -o directory, --operatingdir=directory
              Set the operating directory.  This makes nano set up something similar to a chroot.

       -p, --preserve
              Preserve  the  XON  and  XOFF  sequences  (^Q and ^S) so they will be caught by the
              terminal.

       -q, --quiet
              Obsolete option.  Recognized but ignored.

       -r number, --fill=number
              Hard-wrap lines at column number.  If this value is 0 or less, wrapping will  occur
              at  the  width  of  the screen less number columns, allowing the wrap point to vary
              along with the width of the screen if the screen is resized.  The default value  is
              -8.  This option conflicts with -w (--nowrap) -- the last one given takes effect.

       -s program, --speller=program
              Use this alternative spell checker command.

       -t, --tempfile
              Save a changed buffer without prompting (when exiting with ^X).

       -u, --unix
              Save  a  file by default in Unix format.  This overrides nano's default behavior of
              saving a file in the format that it had.  (This option has no effect when you  also
              use --noconvert.)

       -v, --view
              Just view the file and disallow editing: read-only mode.  This mode allows the user
              to open also other files for viewing, unless --restricted is given too.

       -w, --nowrap
              Disable the hard-wrapping of long lines.  This option conflicts with -r (--fill) --
              the last one given takes effect.

       -x, --nohelp
              Don't show the two help lines at the bottom of the screen.

       -y, --afterends
              Make Ctrl+Right stop at word ends instead of beginnings.

       -z, --suspend
              Enable the suspend ability.

       -$, --softwrap
              Enable 'soft wrapping'.  This will make nano attempt to display the entire contents
              of any line, even if it is longer than the screen  width,  by  continuing  it  over
              multiple  screen lines.  Since '$' normally refers to a variable in the Unix shell,
              you should specify this option last when using other options (e.g. 'nano -wS$')  or
              pass it separately (e.g. 'nano -wS -$').

       -b, -e, -f, -j
              Ignored, for compatibility with Pico.

TOGGLES

       Several  of  the above options can be switched on and off also while nano is running.  For
       example, M-L toggles the hard-wrapping of  long  lines,  M-$  toggles  soft-wrapping,  M-#
       toggles line numbers, M-M toggles the mouse, M-I auto-indentation, and M-X the help lines.
       See at the end of the ^G help text for a complete list.

INITIALIZATION FILE

       nano will read two configuration files: first the system's nanorc (if it exists), and then
       the  user's  nanorc  (if  it  exists), either ~/.nanorc or $XDG_CONFIG_HOME/nano/nanorc or
       ~/.config/nano/nanorc, whichever is encountered first.  See nanorc(5) for more information
       on the possible contents of those files.

NOTES

       If no alternative spell checker command is specified on the command line nor in one of the
       nanorc files, nano will check the SPELL environment variable for one.

       In some cases nano will try to dump the buffer into an emergency file.  This  will  happen
       mainly  if  nano  receives  a  SIGHUP or SIGTERM or runs out of memory.  It will write the
       buffer into a file named nano.save if the buffer didn't have a name already, or will add a
       ".save"  suffix  to  the  current  filename.   If an emergency file with that name already
       exists in the current directory, it will add ".save" plus a number (e.g. ".save.1") to the
       current filename in order to make it unique.  In multibuffer mode, nano will write all the
       open buffers to their respective emergency files.

BUGS

       Justifications (^J) are  not  yet  covered  by  the  general  undo  system.   So  after  a
       justification  that  is  not  immediately undone, earlier edits cannot be undone any more.
       The workaround is, of course, to exit without saving.

       The recording and playback of keyboard macros works correctly only on a terminal emulator,
       not  on  a Linux console (VT), because the latter does not by default distinguish modified
       from unmodified arrow keys.

       Please report any other bugs that you encounter via:
       https://savannah.gnu.org/bugs/?group=nano.

       When nano crashes, it will save any modified buffers to emergency .save files.  If you are
       able  to  reproduce  the  crash  and  you  want to get a backtrace, define the environment
       variable NANO_NOCATCH.
