backup that module list

One of the biggest pains in the ass for me is upgrading perl manually and trying to get all the modules back in. I found this handy dandy post which shows off the following method.

# Backup your current module list
perl -MCPAN -e autobundle
# That will create a file with a name like
# /root/.cpan/Bundle/Snapshot_yyyy_mm_dd_00.pm

perl -MCPAN -e ‘install Bundle::Snapshot_yyyy_mm_dd_00’ | tee \
perl_module_upgrade_results.txt
