.SH NAME
nanorc \- GNU nano's rcfile
.SH DESCRIPTION
This manual page briefly documents GNU \fBnano\fP's rcfile.
.PP
\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".
.PP
The \fInanorc\fP file contains the default settings for \fBnano\fP. It
should not be in DOS or Mac format. During startup, \fBnano\fP will
first read its system-wide settings from \fISYSCONFDIR/nanorc\fP, and
then user-specific settings from \fI~/.nanorc\fP.
The \fInanorc\fP file contains the default settings for \fBnano\fP, a

system-wide settings, from \fBSYSCONFDIR/nanorc\fP, and then the
user-specific settings, from \fB~/.nanorc\fP.
.SH OPTIONS
The configuration file accepts a series of \fBset\fP and \fBunset\fP
commands, which can be used to configure nano on startup without using
the command line options. Additionally, the \fBsyntax\fP, \fBcolor\fP,
and \fBicolor\fP keywords are used to define syntax highlighting rules
for different text patterns. \fBnano\fP will read one command per line.
command-line options. Additionally, there are some commands to define
syntax highlighting and to rebind keys -- see the two separate sections
on those. \fBnano\fP reads one command per line.
Options in \fInanorc\fP files take precedence over nano's defaults, and
command line options override \fInanorc\fP settings. Also, options are
command-line options override \fInanorc\fP settings. Also, options are
unset by default, except for those that take arguments.
Quotes inside string parameters don't have to be escaped with
backslashes. The last double quote in the string will be treated as its
end. For example, for the \fBbrackets\fP option, "\fI"')>]}\fP" will
match \fI"\fP, \fI'\fP, \fI)\fP, \fI>\fP, \fI]\fP, and \fI}\fP.
