cpan - easily interact with CPAN from the command line
# 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]
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.
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.
Creates the CPAN.pm autobundle with CPAN::Shell->autobundle.
Shows the primary maintainers for the specified modules
Show the Changes files for the specified modules
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 This prints one line for each out-of-date module (meaning, modules locally installed but have newer versions on CPAN).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.
List the modules by the specified authors.
Prints a help message.
Show the out-of-date modules.
Recompiles dynamically loaded modules with CPAN::Shell->recompile.
Print the script version and CPAN.pm version.
These options are mutually exclusive, and the script processes them in alphabetical order. It only processes the first one it finds.
Runs a `make clean` in the specified module's directories.
Forces the specified action, when it normally would have failed.
Installed the specified modules.
Makes the specified modules.
Runs a `make test` on the specified modules.
# 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
* none noted
Most behaviour, including environment variables and configuration, comes directly from CPAN.pm.

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