rnano

RNANO(1)						      General Commands Manual							  RNANO(1)

NAME

       rnano - Restricted mode for Nano's ANOther editor, an enhanced free Pico clone

SYNOPSIS

       rnano [OPTIONS] [[+LINE,COLUMN] FILE]...

DESCRIPTION

       This manual page briefly documents the rnano command.

       nano 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, nano also implements some missing (or disabled by  default)  features  in  Pico,  such  as  "search  and
       replace" and "go to line and column number".

       rnano  is  a  restricted  version of nano, which only edits specific files and doesn't allow the user access to the filesystem or a command
       shell.

       In restricted mode, nano will not:

       o read or write to any file not specified on the command line;

       o read any nanorc files;

       o allow suspending;

       o allow a file to be appended to, prepended to, or saved under a different name;

       o use backup files or spell checking.

OPTIONS

       +LINE,COLUMN
	      Places cursor at line number LINE and column number COLUMN (at least one of which must be specified)  on	startup,  instead  of  the
	      default of line 1, column 1.

       -?     Same as -h (--help).

       -h (--help)
	      Show a summary of command line options and exit.

       -V (--version)
	      Show the current version number and exit.

       See the nano(1) manpage for the complete documentation of nano.
