  • Do this or its equivalent.

    perldoc -t perllocal \
      | perl -lne 'print $1 if /"Module" (\S+)/'
      | xargs -n 1 cpan
    • Good idea, except for one detail: the module list is not the list from this installation of perl, but of the previous one, that has already been deleted. So it needs to be a multi-step process:
      1. save the module list to a file
      2. reinstall perl
      3. run the rest of your oneliner using that file as its input
