* New option -q, --quiet, rcfile option "quiet" implemented. Skips printing
errors about the rcfile and asking user to press enter. Also, nano should
now only ask for one enter press when there is an error when not using -q.
Based on discussion between Eitan Adler and Mike Frysinger.
* rcfile.c (parse_keybinding) - Significant cleanups and fixes for
detecting and reporting errors in key bindings code.

.SH NAME
|
|
nano \- Nano's ANOther editor, an enhanced free Pico clone
|
|
|
|
.SH SYNOPSIS
|
|
.B nano
|
|
.I [OPTIONS]\ [[\+LINE,COLUMN]\ FILE]...
|
|
.br
|
|
|
|
.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.

|
|
.TP
|
|

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

|
|
.TP
|
|
.B \-Q \fIstr\fP (\-\-quotestr=\fIstr\fP)
|
|
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

.TP
|
|
.B \-T \fIcols\fP (\-\-tabsize=\fIcols\fP)
|
|

|
|
.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 \-q (\-\-quiet)
|
|
Do not report errors in the nanorc file and ask them to
|
|
be acknowledged by pressing enter at startup.
|
|
.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
|
|
.B \-t (\-\-tempfile)
|

|
|
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)

|
|
.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.
|
|
|
|
