.SH NAME

.SH DESCRIPTION
|
|
This manual page documents briefly 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 number".
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \+\fILINE\fP,\fICOLUMN\fP]

|
|
|
|
.SH INITIALIZATION FILE
|
|
\fBnano\fP will read initialization files in the following order:
|
|
.IR SYSCONFDIR/nanorc ,
|
|
then
|
|
.IR ~/.nanorc .
|
|
Please see
|
|
.BR nanorc (5)
|
|
and the example file \fBnanorc.sample\fP 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.
|
|
|
|
\fBnano\fP will try to dump the buffer into an emergency file in some
|
|
cases. Mainly, this will happen if \fBnano\fP receives a SIGHUP or
|
|
SIGTERM or runs out of memory, when it will write the buffer into a file
|
|
named
|
|
.I 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, \fBnano\fP will write all the open buffers to the
|
|
respective emergency files.
