NANO(1)

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

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

DESCRIPTION
nano is a small, free and friendly editor which aims to replace Pico, the default editor included in the non-free Pine package. On top of 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 the cursor on line number line and at column number column (at least one of which must be specified) on startup, instead of the default line 1, column 1.

-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 tilde (~).

-C directory, --backupdir=directory
    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 support for them has been compiled in).

-G, --locking
    Enable 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 titlebar as extra editing space.

-P, --poslog
    Log and later read back the location of the cursor and place it there again.

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

-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 the available command-line options and exit.

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

-k, --cut
    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, --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 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 -- the last one given takes effect.

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

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

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

-w, --nowrap
    Disable the hard-wrapping of long lines. This option conflicts with -r -- 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$') or pass it separately (e.g. 'nano -wS -$').

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

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.
