this is lame, but w/e… i thought somebody might find it useful.
i feel like a bad ass because i just used the ‘man’ command in Bash in a serious way. i thought about just looking for an explanation about how to do this stuff online, but instead i typed ‘man zip’ to figure out how to take 40gb of data and archive / password protect / split into 4.8gb blocks.
the final command was:
$ zip -P myweakpassword -r -s 4800m archive.zip archivedirectory/
… and it’s working as we speak.
w00t. thanks linux gods, for teaching me to fish.
