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.

       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 the
       .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
              Log search and replace strings to ~/.nano/search_history, so they can be  retrieved
              in later sessions.

       -I, --ignorercfiles
              Don't look at the system's nanorc nor at ~/.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 add newlines to the ends of files.

       -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
              Do  not  report  errors  in  the  nanorc  files  nor ask them to be acknowledged by
              pressing Enter at startup.

       -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.

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  initialization  files in the following order: the system's nanorc (if it
       exists), and then the user's ~/.nanorc (if it exists).   Please  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) and reindentations (M-{ and M-}) are not yet covered  by  the  general
       undo  system.   So  after  a  justification  that  is not immediately undone, or after any
       reindentation, earlier edits cannot be undone any more.  The workaround is, of course,  to
       exit without saving.

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