^G Help Text

The nano editor is designed to emulate the functionality and ease-of-use of the UW Pico text editor. There are four main sections of the editor. The top line shows the program version, the current filename being edited, and whether or not the file has been modified. Next is the main editor window showing the file being edited. The status line is the third line from the bottom and shows important messages. The bottom two lines show the most commonly used shortcuts in the editor.

The notation for shortcuts is as follows: Control-key sequences are notated with a caret (^) symbol and can be entered either by using the Control (Ctrl) key or pressing the Escape (Esc) key twice. Escape-key sequences are notated with the Meta (M-) symbol and can be entered using either the Esc, Alt, or Meta key depending on your keyboard setup. Also, pressing Esc twice and then typing a three-digit decimal number from 000 to 255 will enter the character with the corresponding value. The following keystrokes are available in the main editor window. Alternative keys are shown in parentheses:

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

SYNOPSIS
       nano [OPTIONS] [[+LINE,COLUMN] FILE]...

DESCRIPTION
       This manual page briefly documents the nano command.

       nano  is  a  small,  free  and friendly  editor  which  aims to replace Pico, the default editor 
       included in the non-free Pine package.  Rather than just copying Pico's look and feel, nano also
       implements some missing (or disabled by default) features  in Pico, such as "search and replace" 
       and "go to line and column number".

OPTIONS
       +LINE,COLUMN
              Places cursor at line number LINE and column number COLUMN (at least one of which must be
              specified) on startup, instead of the default of line 1, column 1.

       -?     Same as -h (--help).

       -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 to the current filename suffixed 
              with a ~.

       -C dir (--backupdir=dir)
              Set the directory where nano puts unique backup files if file backups are enabled.

       -D (--boldtext)
              Use bold text instead of reverse video text.

       -E (--tabstospaces)
              Convert typed tabs to spaces.

       -F (--multibuffer)
              Enable multiple file buffers, if available.

       -H (--historylog)
              Log search and replace strings to ~/.nano_history, so they can be retrieved in later  
              sessions, if nanorc support is available.

       -I (--ignorercfiles)
              Don't look at SYSCONFDIR/nanorc or ~/.nanorc, if nanorc support is available.

       -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 titlebar as extra editing space.

       -Q str (--quotestr=str)
              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; read
              any nanorc files; allow suspending; allow a file to be appended to, prepended to, or saved 
              under a different name if it already has one; or use backup files or spell checking.  Also
              accessible by invoking nano with any name  beginning with 'r' (e.g. "rnano").

       -S (--smooth)
              Enable smooth scrolling. Text will scroll line-by-line, instead of the usual chunk-by-chunk
              behavior.

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

       -U (--quickblank)
              Do  quick  statusbar blanking.  Statusbar messages will disappear after 1 keystroke instead
              of 25.  Note that -c overrides this.

       -V (--version)
              Show the current version number and exit.

       -W (--wordbounds)
              Detect word boundaries more accurately by treating punctuation characters as part of a word.

       -Y str (--syntax=str)
              Specify a specific syntax highlighting from the nanorc to use, if available.

       -c (--const)
              Constantly show the cursor position.  Note that this overrides -U.

       -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.

       -h (--help)
              Show a summary of command line options and exit.

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

       -k (--cut)
              Enable cut from cursor to end of line.

       -l (--nofollow)
              If  the  file  being  edited is a symbolic link, replace the link with a new file instead of 
              following it.  Good for editing files in /tmp, perhaps?

       -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 short-cuts. The mouse 
              will work in the X Window System, and on the console when gpm is running.

       -o dir (--operatingdir=dir)
              Set operating directory.  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.

       -r cols (--fill=cols)
              Wrap  lines  at column cols. If this value is 0 or less, wrapping will occur at the width of
              the  screen  less  cols columns, allowing the wrap point to vary along with the width of the 
              screen if the screen is resized.  The default value is -8.

       -s prog (--speller=prog)
              Enable alternative spell checker command.

       -t (--tempfile)
              Always save changed buffer without prompting.  Same as Pico's -t option.
                    -o dir (--operatingdir=dir)
              Set operating directory.  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.

       -r cols (--fill=cols)
              Wrap  lines at  column cols. If this value is 0 or less, wrapping will occur at the width of
              the screen  less  cols columns, allowing the wrap  point to vary along with the width of the 
              screen if the screen is resized.  The default value is -8.

       -s prog (--speller=prog)
              Enable alternative spell checker command.

       -t (--tempfile)
              Always save changed buffer without prompting.  Same as Pico's -t option.

       -v (--view)
              View file (read only) mode.

       -w (--nowrap)
              Disable wrapping of long lines.

       -x (--nohelp)
              Disable help screen at bottom of editor.

       -z (--suspend)
              Enable suspend ability.

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

INITIALIZATION FILE

       nano will read initialization files in the following order: SYSCONFDIR/nanorc, then ~/.nanorc. Please 
       see nanorc(5) and the example file nanorc.sample, both of which  should be provided with nano.

NOTES
       If no alternative spell checker command is specified on the command line or 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.
