.SH NAME
|
|
nano \- Nano's ANOther editor, an enhanced free Pico clone
|
|
|
|
.SH SYNOPSIS
|
|
.B nano

|
.I [OPTIONS]\ [[\+LINE,COLUMN]\ FILE]...
|
|

|
|
|
|
.SH DESCRIPTION
|
|
This manual page briefly documents the \fBnano\fP command.
|
|
.PP
|
|
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
|
|
.\" \fI<whatever>\fP escape sequences to invoke bold face and italics,
|
|
.\" respectively.
|
|
\fBnano\fP 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, \fBnano\fP also implements some
|
|
missing (or disabled by default) features in Pico, such as "search and
|
|
replace" and "go to line and column number".
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \+\fILINE\fP,\fICOLUMN\fP
|
|
Places cursor at line number \fILINE\fP and column number \fICOLUMN\fP
|
|
(at least one of which must be specified) on startup, instead of the
|
|
default of line 1, column 1.
|
|
.TP
|
|
.B \-?
|
|
Same as \fB-h (\-\-help)\fP.
|
|
.TP
|
|
.B \-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.
|
|
.TP
|
|
.B \-B (\-\-backup)
|
|
When saving a file, back up the previous version of it to the current
|
|
filename suffixed with a ~.
|
|
.TP
|
|
.B \-C \fIdir\fP (\-\-backupdir=\fIdir\fP)
|
|
Set the directory where \fBnano\fP puts unique backup files if file
|
|
backups are enabled.

Enable multiple file buffers, if available.
|
|
.TP
|
|
.B \-H (\-\-historylog)

retrieved in later sessions, if nanorc support is available.
|
|
.TP
|
|
.B \-I (\-\-ignorercfiles)
|
|
Don't look at \fISYSCONFDIR/nanorc\fP or \fI~/.nanorc\fP, if nanorc
|
|
support is available.
|
|
.TP
|
|
.B \-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.
|
|
.TP
|
|
.B \-L (\-\-nonewlines)
|
|
Don't add newlines to the ends of files.
|
|

|
|
.TP
|
|

|
|
Set the quoting string for justifying. The default is
|
|
"\fI^([\ \\t]*[#:>\\|}])+\fP" if extended regular expression support is
|
|
available, or "\fI>\ \fP" otherwise. Note that \fI\\t\fP stands for a
|
|
Tab.
|
|
.TP
|
|
.B \-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 \fBnano\fP with any name beginning with 'r' (e.g. "rnano").
|
|
.TP
|
|
.B \-S (\-\-smooth)

|
Enable smooth scrolling. Text will scroll line-by-line, instead of the

|
|
.B \-Y \fIstr\fP (\-\-syntax=\fIstr\fP)
|
|
Specify a specific syntax highlighting from the \fInanorc\fP to use, if
|
|
available.
|
|
.TP
|
|
.B \-c (\-\-const)
|
|
Constantly show the cursor position. Note that this overrides \fB-U\fP.
|
|
.TP
|
|
.B \-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.
|
|
.TP
|
|
.B \-h (\-\-help)
|
|
Show a summary of command line options and exit.
|
|
.TP
|

|
|
.TP
|
|
.B \-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
|
|
\fI/tmp\fP, perhaps?
|
|
.TP
|
|
.B \-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.
|
|
.TP
|
|
.B \-o \fIdir\fP (\-\-operatingdir=\fIdir\fP)
|
|
Set operating directory. Makes \fBnano\fP set up something similar to a
|
|
chroot.
|
|
.TP
|
|
.B \-p (\-\-preserve)
|
|
Preserve the XON and XOFF sequences (^Q and ^S) so they will be caught
|
|
by the terminal.
|
|
.TP
|
|
.B \-r \fIcols\fP (\-\-fill=\fIcols\fP)
|
|
Wrap lines at column \fIcols\fP. If this value is 0 or less, wrapping
|
|
will occur at the width of the screen less \fIcols\fP columns, allowing
|
|
the wrap point to vary along with the width of the screen if the screen
|
|
is resized. The default value is -8.
|
|
.TP
|
|
.B \-s \fIprog\fP (\-\-speller=\fIprog\fP)
|
|
Enable alternative spell checker command.
|
|
.TP
|

|
|
option.
|
|
.TP
|
|
.B \-v (\-\-view)
|
|
View file (read only) mode.
|
|
.TP
|
|
.B \-w (\-\-nowrap)
|
|

|
|
.TP
|
|
.B \-x (\-\-nohelp)
|
|
Disable help screen at bottom of editor.
|
|
.TP
|
|
.B \-z (\-\-suspend)
|
|
Enable suspend ability.
|
|
.TP
|
|
.B \-a, \-b, \-e, \-f, \-g, \-j
|
|
Ignored, for compatibility with Pico.
|
|
|
|
.SH INITIALIZATION FILE
|
|
\fBnano\fP will read initialization files in the following order:
|
|
\fISYSCONFDIR/nanorc\fP, then \fI~/.nanorc\fP. Please see
|
|
\fBnanorc(5)\fP and the example file \fBnanorc.sample\fP, both of which
|
|
should be provided with \fBnano\fP.
|
|
|
|
.SH NOTES
|
|
If no alternative spell checker command is specified on the command
|
|
line or in one of the nanorc files, \fBnano\fP will check the
|
|
\fBSPELL\fP environment variable for one.
|
|
|
|
In some cases \fBnano\fP will try to dump the buffer into an emergency
|
|
file. This will happen mainly if \fBnano\fP receives a SIGHUP or
|
|
SIGTERM or runs out of memory. It will write the buffer into a file
|
|
named \fInano.save\fP 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, \fBnano\fP will write all the open
|
|
buffers to their respective emergency files.
|
|
|
|
