NAME

cpan - easily interact with CPAN from the command line

SYNOPSIS

        # with arguments and no switches, installs specified modules
        cpan module_name [ module_name ... ]

        # with switches, installs modules with extra behavior
        cpan [-cfimt] module_name [ module_name ... ]

        # without arguments, starts CPAN.pm shell
        cpan

        # without arguments, but some switches
        cpan [-ahrvACDLO]

DESCRIPTION

This script provides a command interface (not a shell) to CPAN. At the moment it uses CPAN.pm to do the work, but it is not a one-shot command runner for CPAN.pm.

Meta Options

These options are mutually exclusive, and the script processes them in this order: [hvCAar]. Once the script finds one, it ignores the others, and then exits after it finishes the task. The script ignores any other command line options.

-a: Creates the CPAN.pm autobundle with CPAN::Shell->autobundle.
-A module [ module ... ]: Shows the primary maintainers for the specified modules
-C module [ module ... ]: Show the "Changes" files for the specified modules
-D module [ module ... ]: Show the module details. This prints one line for each out-of-date module (meaning, modules locally installed but have newer versions on CPAN). Each line has three columns: module name, local version, and CPAN version.
-L author [ author ... ]: List the modules by the specified authors.
-h: Prints a help message.
-O: Show the out-of-date modules.
-r: Recompiles dynamically loaded modules with CPAN::Shell->recompile.
-v: Print the script version and CPAN.pm version.

Module options

These options are mutually exclusive, and the script processes them in alphabetical order. It only processes the first one it finds.

c: Runs a `make clean` in the specified module's directories.
f: Forces the specified action, when it normally would have failed.
i: Installed the specified modules.
m: Makes the specified modules.
t: Runs a `make test` on the specified modules.

Examples

        # print a help message
        cpan -h

        # print the version numbers
        cpan -v

        # create an autobundle
        cpan -a

        # recompile modules
        cpan -r

        # install modules ( sole -i is optional )
        cpan -i Netscape::Booksmarks Business::ISBN

        # force install modules ( must use -i )
        cpan -fi CGI::Minimal URI

If, for some reason, I disappear from the world, one of the other members of the project can shepherd this module appropriately.

CREDITS

Japheth Cleaver added the bits to allow a forced install (-f).

Jim Brandt suggest and provided the initial implementation for the up-to-date and Changes features.

Adam Kennedy pointed out that exit() causes problems on Windows where this script ends up with a .bat extension
