CPAN(1) Perl Programmers Reference Guide CPAN(1)

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 This prints one line for each out-of-date module (meaning, modules locally installed but have newer versions on CPAN).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-O Show the out-of-date modules.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

TO DO BUGS * none noted

SEE ALSO Most behaviour, including environment variables and configuration, comes directly from CPAN.pm.

SOURCE AVAILABILITY This source is part of a SourceForge project which always has the latest sources in CVS, as well as all of the previous releases.

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
