nano - Nano’s ANOther editor, an enhanced free Pico clone
nano [+LINE] [options] [file]
This manual page documents briefly 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 number".
+LINE Places cursor at LINE on startup.
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 back-
wards). If the cursor is already at that position, it will jump
to the true beginning of the line.
When saving a file, back up the previous version of it to the
current filename suffixed with a ~.
-E dir (--backupdir=dir)
Set the directory where nano puts the backup files if file back-
ups are enabled.
Enable multiple file buffers, if available.
Log search and replace strings to ~/.nano_history so they may be
stored for later editing, if nanorc support is configured.
Don’t look at SYSCONFDIR/nanorc or ~/.nanorc, if nanorc support
Disable automatic conversion of files from DOS/Mac format.
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 regular expression support is available,
or "> " otherwise.
Enable regular expression matching for search strings, as well
as \n subexpression replacement for replace strings, if avail-
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.
Show the current version number and author.
-Y str (--syntax=str)
Specify a specific syntax highlighting from the nanorc to use,
Restricted mode: Don’t read or write to any file not specified
on the command line, read any nanorc files, allow suspending, or
allow a file to be appended to, prepended to, or saved under a
different name if it already has one. Also accessible by invok-
ing nano with any name beginning with ’r’ (e.g. "rnano").
Constantly show the cursor position.
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.
Display a summary of command line options.
Indent new lines to the previous line’s indentation. Useful
when editing source code.
Enable cut from cursor to end of line with ^K.
If the file being edited is a symbolic link, replace the link
with a new file, do not follow it. Good for editing files in
Enable mouse support (if available for your system).
-o dir (--operatingdir=dir)
Set operating directory. Makes nano set up something similar to
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. By default, this is the width of the
screen, less eight. If this value is negative, wrapping will
occur at cols columns from the right of the screen, allowing the
wrap point to vary along with the screen width if resized.
-s prog (--speller=prog)
Enable alternative spell checker command.
Always save changed buffer without prompting. Same as Pico -t
View file (read only) mode.
Disable wrapping of long lines.
Disable help screen at bottom of editor.
Enable suspend ability.
-a, -b, -e, -f, -g, -j
Ignored, for compatibility with Pico.
nano will read initialization files in the following order:
SYSCONFDIR/nanorc, then ~/.nanorc. Please see nanorc(5) and the exam-
ple file nanorc.sample which should be provided with nano.
If no alternative spell checker command is specified on the command
line or in one of the nanorc files, nano will check the SPELL environ-
ment variable for one.
nano will try to dump the buffer into an emergency file in some cases.
Mainly, this will happen if nano receives a SIGHUP or SIGTERM or runs
out of memory, when 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, ".save" and a number
(e.g. ".save.1") will be suffixed to the current filename in order to
make it unique. In multibuffer mode, nano will write all the open
buffers to the respective emergency files.
