Devel::Loaded - Post-execution dump of loaded modules
perl -MDevel::Loaded programname 2>/dev/null
The Devel::Loaded module installs an at-exit handler to generate a dump of all the module files used by a Perl program. If used in conjunction with a perl -c, you find those files loaded in at compile time with use. If you are willing to wait until after the program runs, you can get them all.
use
This is compile-time only:
$ perl -MDevel::Loaded perldoc 2>/dev/null /usr/local/devperl/lib/5.00554/Exporter.pm /usr/local/devperl/lib/5.00554/strict.pm /usr/local/devperl/lib/5.00554/vars.pm /usr/local/devperl/lib/5.00554/i686-linux/Config.pm /usr/local/devperl/lib/5.00554/Getopt/Std.pm
This will also catch run-time loads:
#!/usr/bin/perl use Devel::Loaded; ...
The plxload and the pmload programs, which use this technique.
