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


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


       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.


       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.

       Since nano-2.7.0, text can also be selected by holding Shift and moving
       the  cursor  with  the  arrow  keys.  Holding down the Alt key too will
       increase the stride.

       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).


       -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

       -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

       -L, --nonewlines
              Don't add newlines to the ends of files.

       -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.  (The old form of this option, --poslog, is deprecated.)

       -Q "characters", --quotestr="characters"
              Set  the  quoting  string  for  justifying.   The   default   is
              "^([ \t]*[#:>\|}])+"  if  extended regular expression support is
              available, or "> " otherwise.  Note that \t stands for a Tab.

       -R, --restricted
              Restricted mode: don't read or write to any file  not  specified
              on  the  command  line;  don't read any nanorc files nor history
              files; don't allow suspending nor 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 use  backup  files.   This
              restricted  mode  is  also  accessible 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.

       -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.  Useful for braille users.

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

       -i, --autoindent
              Indent  new  lines  to  the previous line's indentation.  Useful
              when editing source code.

       -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.

       -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.

       -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.


       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.


       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.


       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 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.


       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 is a
       deficient terminal.
