NAME
nano - Nano's ANOther text editor, inspired by Pico
SYNOPSIS
nano [options] [[+line[,column
nano [options] [[+[
DESCRIPTION
nano is a small and friendly text editor. It copies the look and feel
of Pico, but is free software, and implements a few 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.
Negative numbers count from the end of the file or line.
The cursor can be put on the first or last occurrence of a specific
string by specifying that string after +/ or +? before the filename.
The string can be made case sensitive and/or caused to be interpreted
as a regular expression by inserting c and/or r after the + sign.
These search modes can be explicitly disabled by using the uppercase
variant of those letters: C and/or R. When the string contains
spaces, it needs to be enclosed in quotes. To give an example: to
open a file at the first occurrence of the word "Foo", you would do:
nano +c/Foo file
As a special case: if instead of a filename a dash (-) is given, nano
will read data from standard input.
NOTICES
Since version 9.0, all lines are scrolled horizontally together (when
the cursor approaches the edge), by just the amount needed, instead of
scrolling only the current line by a large step. If you prefer the
old behavior, you can use --solo on the command line or set
solosidescroll in your nanorc.
Also since version 9.0, keystrokes M-< and M-> have been reassigned to
the scrollleft and scrollright functions. If you want those
keystrokes to do what they did before version 9.0, add these two lines
at the end of your nanorc file:
bind M-< prevbuf main
bind M-> nextbuf main

Since version 8.0, to be newcomer friendly, ^F starts a forward
search, ^B starts a backward search, M-F searches the next occurrence
forward, and M-B searches the next occurrence backward. If you want
those keystrokes to do what they did before version 8.0, add the
following four lines at the end of your nanorc file:
bind ^F forward main
bind ^B back main
bind M-F formatter main
bind M-B linter main
EDITING
Entering text and moving around in a file are 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 put all deleted lines together in the cutbuffer. Any
cursor movement or executing any other command causes the next ^K to
overwrite the cutbuffer. A ^U pastes the current contents of the
cutbuffer at the current cursor position.
When a more precise piece of text needs to be cut or copied, you can
mark its start with ^6, move the cursor to its end (the marked text is
highlighted), and then use ^K to cut it, or M-6 to copy it to the
cutbuffer. You can also save the marked text to a file with ^O, or
spell check it with ^T^T.
On some terminals, text can be selected also by holding down Shift
while using the arrow keys. Holding down the Ctrl or Alt key too
increases the stride. Any cursor movement without Shift being held
cancels such a selection.
Any valid Unicode code point can be inserted into the buffer by typing
M-V followed by the hexadecimal digits of the code point (concluded
with <Space> or <Enter> when it are fewer than six digits). A literal
control code (except ^J) can be inserted by typing M-V followed by the
pertinent keystroke.
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 [em] 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 jumps to that beginning (either forwards or backwards).
- 2 - Formatted: June 24, 2026
NANO(1) GNU nano 9.1 NANO(1)
June 2026
If the cursor is already at that position, it jumps 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 ([ti]).
-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 [em] when
backups are enabled (-B). The uniquely numbered files are stored
in the specified directory.
-D, --boldtext
For the interface, use bold instead of reverse video. This can
be overridden for specific elements by setting the options
titlecolor, statuscolor, promptcolor, minicolor, keycolor,
numbercolor, and/or selectedcolor in your nanorc file. See
nanorc(5).
-E, --tabstospaces
Convert each typed tab to spaces [em] to the number of spaces
that a tab at that position would take up. (Note: pasted tabs
are not converted.)
-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
sessions.
-I, --ignorercfiles
Don't look at the system's nanorc nor at the user's nanorc.
-J number, --guidestripe=number
Draw a vertical stripe at the given column, to help judge the
width of the text. (The color of the stripe can be changed with
set stripecolor in your nanorc file.)
-K, --rawsequences
Interpret escape sequences directly, instead of asking ncurses to
translate them. (If you need this option to get some keys to
work properly, it means that the terminfo terminal description
that is used does not fully match the actual behavior of your
terminal. This can happen when you ssh into a BSD machine, for
example.) Using this option disables nano's mouse support.
- 3 - Formatted: June 24, 2026

-L, --nonewlines
Don't automatically add a newline when a text does not end with
one. (This can cause you to save non-POSIX text 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 format.
-O, --bookstyle
When justifying, treat any line that starts with whitespace as
the beginning of a paragraph (unless auto-indenting is on).
-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. Also save and restore the positions of any anchors.
-Q regex,--quotestr=
Set the regular expression for matching the quoting part of a
line. The default value is "^([ \t]*([!#%:;>|}]|//))+". (Note
that \t stands for an actual Tab.) This makes it possible to
rejustify blocks of quoted text when composing email, and to
rewrap blocks of line comments when writing source code.
-R, --restricted
Read and write only the file (or files) specified on the command
line. This means: don't read or write the history files; don't
allow suspending; don't allow spell checking; don't allow
executing any command in the shell; don't allow the current
buffer to be saved under a different name; don't allow appending
or prepending to any file; and don't make backup files.
As an exception, before the specified file or files, the nanorc
files are read, to allow customization. If customization should
not be allowed, use option -I (--ignorercfiles) as well.
When no file is specified on the command line, restricted mode
allows you to save the contents that you type into the new buffer
under any name, except that existing files may not be
overwritten. If the places where this new file may be created
should be limited, then use option -o (--operatingdir) as well.
Restricted mode can also be activated by invoking nano with a
name beginning with 'r' (for example: rnano).
-S, --softwrap
Display over multiple screen rows lines that exceed the screen's
width. (You can make this soft-wrapping occur at whitespace
- 4 - Formatted: June 24, 2026
NANO(1) GNU nano 9.1 NANO(1)
June 2026
instead of rudely at the screen's edge, by using also ---
atblanks.)
-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
Make status-bar messages disappear after 1 keystroke instead of
after 20. Note that option -c (--constantshow) overrides this.
When option --minibar or --zero is in effect, --quickblank makes
a message disappear after 0.8 seconds instead of after the
default 1.5 seconds.
-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=
Specify which other characters (besides the normal alphanumeric
ones) should be considered as part of a word. When using this
option, you probably want to omit -W (--wordbounds).
-Y name, --syntax=name
Specify the name of the syntax highlighting to use from among the
ones defined in the nanorc files.
-Z, --zap
Let an unmodified Backspace or Delete erase the marked region
(instead of a single character, and without affecting the
cutbuffer).
-a, --atblanks
When doing soft line wrapping, wrap lines at whitespace instead
of always at the edge of the screen.
-b, --breaklonglines
Automatically hard-wrap the current line when it becomes
overlong, that is: when it becomes wider than the value given
with -r (--fill). The default value for -r is the terminal's
width minus eight. (This option is the opposite of -w (--nowrap)
[em] the last one given takes effect.)
-c, --constantshow
Constantly report the cursor position on the status bar. Note
that this overrides option -U (--quickblank).

-d, --rebinddelete
Interpret the Delete and Backspace keys differently so that both
Backspace and Delete work properly. You should only use this
option when on your system either Backspace acts like Delete or
Delete acts like Backspace.
-e, --emptyline
Do not use the line below the title bar, leaving it entirely
blank.
-f file, --rcfile=file
Read only this file for setting nano's options, instead of
reading both the system-wide and the user's nanorc files.
-g, --showcursor
Make the cursor visible in the file browser (putting it on the
highlighted item) and in the help viewer. Useful for braille
users and people with poor vision.
-h, --help
Show a summary of the available command-line options and exit.
-i, --autoindent
Automatically indent a newly created line to the same number of
tabs and/or spaces as the previous line (or as the next line if
the previous line is the beginning of a paragraph).
-j, --jumpyscrolling
Scroll the buffer contents per half-screen instead of per line.
-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. (Any line
with an anchor additionally gets a mark in the margin.)
-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
works 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 starts with a blank
buffer, and writes to the pipe when the user saves the
- 6 - Formatted: June 24, 2026
NANO(1) GNU nano 9.1 NANO(1)
June 2026
[lq]file[rq]. 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
Change to the given directory, and allow reading and writing
files only in this directory and its subdirectories.
-p, --preserve
Preserve the XOFF and XON sequences (^S and ^Q) so that they are
caught by the terminal (stopping and resuming the output). Note
that option -/ (--modernbindings) overrides this.
-q, --indicator
Display a [lq]scrollbar[rq] on the righthand side of the edit
window. It shows the position of the viewport in the buffer and
how much of the buffer is covered by the viewport.
-r number, --fill=number
Set the target width for justifying and automatic hard-wrapping
at this number of columns. If the value is 0 or less, wrapping
occurs at the width of the screen minus 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.
-s "program [argument ...]", --speller="program [argument ...]"
Use this command to perform spell checking and correcting,
instead of using the built-in corrector that calls hunspell(1) or
spell(1).
-t, --saveonexit
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. This
mode allows the user to open also other files for viewing, unless
--restricted is given too.
-w, --nowrap
Do not automatically hard-wrap the current line when it becomes
overlong. This is the default. (This option is the opposite of
-b (--breaklonglines) [em] the last one given takes effect.)
-x, --nohelp
Don't show the two help lines at the bottom of the screen.
- 7 - Formatted: June 24, 2026

-y, --afterends
Make Ctrl+Right and Ctrl+Delete stop at word ends instead of
beginnings.
-z, --listsyntaxes
List the names of the available syntaxes and exit.
-!, --magic
When neither the file's name nor its first line give a clue, try
using libmagic to determine the applicable syntax.
-@, --colonparsing
When a filename given on the command line ends in a colon plus
digits and this filename does not exist, then snip the colon plus
digits and understand the digits as a line number. If the
trimmed filename does not exist either, then repeat the process
and understand the obtained two numbers as line and column
number. But if the doubly trimmed filename does not exist
either, then forget the trimming and accept the original filename
as is. To disable this colon parsing for some file, use +1 or
similar before the relevant filename.
-%, --stateflags
Use the top-right corner of the screen for showing some state
flags: I when auto-indenting, M when the mark is on, L when
hard-wrapping (breaking long lines), R when recording a macro,
and S when soft-wrapping. When the buffer is modified, a star
(*) is shown after the filename in the center of the title bar.
-_, --minibar
Suppress the title bar and instead show information about the
current buffer at the bottom of the screen, in the space for the
status bar. In this [lq]mini bar[rq] the filename is shown on
the left, followed by an asterisk if the buffer has been
modified. On the right are displayed the current line and column
number, the code of the character under the cursor (in Unicode
format: U+xxxx), the same flags as are shown by --stateflags, and
a percentage that expresses how far the cursor is into the file
(linewise). When a file is loaded or saved, and also when
switching between buffers, the number of lines in the buffer is
displayed after the filename. This number is cleared upon the
next keystroke, or replaced with an [i/n] counter when multiple
buffers are open. The line plus column numbers and the character
code are displayed only when --constantshow is used, and can be
toggled on and off with M-C. The state flags are displayed only
when --stateflags is used.
-0, --zero
Hide all elements of the interface (title bar, status bar, and
help lines) and use all rows of the terminal for showing the
contents of the buffer. The status bar appears only when there
- 8 - Formatted: June 24, 2026
NANO(1) GNU nano 9.1 NANO(1)
June 2026
is a significant message, and disappears after 1.5 seconds or
upon the next keystroke. With M-Z the title bar plus status bar
can be toggled. With M-X the help lines.
-1, --solosidescroll
When the cursor approaches the right edge of the edit window,
scroll only the current line sideways by a large amount, instead
of scrolling all visible lines sideways by just the amount needed
to keep the cursor in view. This latter whole-window smooth
sideways scrolling is the new default behavior. The single-line
jerky sideways scrolling enabled by this option was the old
behavior [em] the only behavior that nano knew.
-/, --modernbindings
Use key bindings similar to the ones that most modern programs
use: ^X cuts, ^C copies, ^V pastes, ^Z undoes, ^Y redoes, ^F
searches forward, ^G searches next, ^S saves, ^O opens a file, ^Q
quits, and (when the terminal permits) ^H shows help.
Furthermore, ^A sets the mark, ^B searches backward, ^D searches
previous, ^R makes replacements, ^P shows the position, ^T goes
to a line, ^W writes out a file, and ^E executes a command. Note
that this option overrides option -p (--preserve).
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-S toggles soft-wrapping, M-N 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.
The M-X toggle is special: it works in all menus except the help
viewer and the linter. All other toggles work in the main menu only.

0 The editor finished normally.
1 An invalid option or option argument was given.
2 The last open buffer was discarded (with ^O^Q or ^X^Q).
NOTES
Suspension is enabled by default, reachable via ^T^Z. (If you want a
plain ^Z to suspend nano, add bind ^Z suspend main to your nanorc.)
At a Yes-No prompt, ^Y can be used for "Yes", ^N for "No", and ^A for
"All". (And when exiting, ^Q can be used for "Quit with error".)
These unlisted bindings work in any locale.
When you want to copy marked text from nano to the system's clipboard,
see one of the examples in the nanorc(5) man page.
If no alternative spell checker command is specified on the command
line nor in one of the nanorc files, nano checks the SPELL environment
variable for one.
In some cases nano tries to dump the buffer into an emergency file.
This happens mainly if nano receives a SIGHUP or SIGTERM or runs out
of memory. It writes the buffer into a file named nano.save if the
buffer didn't have a name already, or adds a ".save" suffix to the
current filename. If an emergency file with that name already exists
in the current directory, it adds ".save" plus a number (for example:
".save.1") to the current filename in order to make it unique. In
multibuffer mode, nano writes all open buffers to their respective
emergency files.
If you have any question about how to use nano in some specific
situation, you can ask on help-nano@gnu.org.
BUGS
The recording and playback of keyboard macros works correctly only on
a terminal emulator, not on a Linux console (VT), because the latter
does not by default distinguish modified from unmodified arrow keys.
Please report any other bugs that you encounter via:
https://savannah.gnu.org/bugs/?group=nano.
When nano crashes, it saves any modified buffers to emergency .save
files. If you are able to reproduce the crash and you want to get a
backtrace, define the environment variable NANO_NOCATCH.
