shstack - Persistent and Easy to Use Stacks Shared Between Shell Sessions

This is an early release. There are bugs. Some of them are purely cosmetic. Some things are actually broken.

shstack lets you push files and directories onto named stacks. The stacks are stored on the file system and can be manipulated and retrieved by other shell sessions.

Known Bugs

• Some Perl warning messages (the ones I saw didn't cause trouble)

backup2.patshead.com
backup1.patshead.com
wonko@zaphod:~$ s push testSource /etc
wonko@zaphod:~$ s push testSource /var/named
wonko@zaphod:~$ s push testSource /home
wonko@zaphod:~$ s for echo rsync %testSource% %testHost%:backups/
rsync /home backup2.patshead.com:backups/
