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 This prints one line for each out-of-date module (meaning, modules locally installed but have newer versions on CPAN).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-O Show the out-of-date modules.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