autobundle

autobundle [bundlelist]

• Writes a bundle file containing a list of all modules that are both available from CPAN and currently installed within @INC. The file is written to the Bundle subdirectory of cpan_home with a name that contains the current date and a counter; for example, Snapshot_1998_04_27_00.pm. You can then use that file as input to the install command to install the latest versions of all the modules on your system:
  
  

  perl -MCPAN -e 'install Bundle::Snapshot_1998_04_27_00'
