Free command line software for linux

Tk::CmdLine contains process standard X11 command line options and set initial resources.

SYNOPSIS

Tk::CmdLine::SetArguments([@argument]);

my $value = Tk::CmdLine::cget([$option]);

Tk::CmdLine::SetResources((@resource | $resource) [, $priority]);

Tk::CmdLine::LoadResources(
[ -symbol => $symbol ]
[ -file => $fileSpec ]
[ -priority => $priority ]
[ -echo => $fileHandle ] );

Process standard X11 command line options and set initial resources.

The X11R5 man page for X11 says: "Most X programs attempt to use the same names for command line options and arguments. All applications written with the X Toolkit Intrinsics automatically accept the following options: ...". This module processes these command line options for perl/Tk applications using the SetArguments function.

This module can optionally be used to load initial resources explicitly via function SetResources, or from specified files (default: the standard X11 application-specific resource files) via function LoadResources.

Getopt::Long is an extended processing of command line options.

SYNOPSIS

use Getopt::Long;
my $data = "file.dat";
my $length = 24;
my $verbose;
$result = GetOptions ("length=i" => $length, # numeric
"file=s" => $data, # string
"verbose" => $verbose); # flag

The Getopt::Long module implements an extended getopt function called GetOptions(). This function adheres to the POSIX syntax for command line options, with GNU extensions.

In general, this means that options have long names instead of single letters, and are introduced with a double dash "--". Support for bundling of command line options, as was the case with the more traditional single-letter approach, is provided but not enabled by default.

Sys::Manage::Cmd - Systems management command volley.

SYNOPSIS

Command line script

use Sys::Manage::Cmd;
my $s =Sys::Manage::Cmd->new();

# Script associations (see also embedded in source):
$s->{-assoc}->{.ftp}=sub{[ftp,-n,-s:loginfile,!elem!,[0]]};

# Target collections:
$s->{-target}->{all} =[1,2,3,4,5,6];

# Target branches:
$s->{-branch}->{1} =[1,2];
$s->{-branch}->{2} =[3,4];
$s->{-branch}->{3} =[5,6];

# Command-line setup / loop:
$s->set([@ARGV]);

# Command assignments:
#$s->set(-k=>assign, -o=>b, -i=>0, -ping=>1);
#$s->execute(-a=>assignment name, -t=>[targets], -cline=>[command line]);
#...

# Command line execution:
$s->set(-k=>cmd, -o=>b, -i=>0, -ping=>0);
$s->execute([@ARGV]);

PyPar2 is a frontend for the Linux par2 command line, written in Python. PyPar2s GUI uses GTK through the PyGTK library.

The current version does not handle the creation of par2 files, only repairing and verifying are available.

Options.pm is a command-line option-parsing Perl module meant to imitate the syntax of the t.p.usage.Options module from the Twisted Python library.

This module will allow you to specify which options to look for on the command line, and supports both long and short versions of simple flags and parameters. If a required parameter is unspecified, Options.pm will print nicely formatted usage information with the error.

Twitter4R project is a clean Twitter client API in pure Ruby (not command-line client) Will include Twitter add-ons also in Ruby.
The Twitter4R Gem is released under the MIT License.
Enhancements:
- The entire Twitter REST API is now covered.
- This library is more complete and more in the Ruby style of coding than the "Twitter Gem" project.
- The latter seems to provide a convenient command-line tool for very basic Twitter REST API usages.

gimmage is an image viewer that is perfect for command line usage as it accepts directories and image filenames as arguments.

It has an in-application file browser that allows users to select and drag images and directories into the image viewing area in order to have them displayed.
