Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

That doesn't work if there are spaces in the filenames.

This does it in 59 chars, not 113 (spaces are OK, but I don't check for dirs):

for i in *; do mv "$i" $(sha1sum "$i" | cut -d\ -f1); done
Comment by flatcap 382 weeks and 1 day ago

This is a bit simpler if you're just doing files in the current working directory.

for i in *;do mv "$i" $(sha1sum "$i" | cut -d" " -f1);done
Comment by eightmillion 382 weeks ago

Actually, my version needs a directory check:

for i in *;do [ -f "$i" ] && mv "$i" $(sha1sum "$i"|cut -d" " -f1);done
Comment by eightmillion 382 weeks ago

60 chars, but more beautiful:

eval $(sha1sum * | sed 's/^\(\w*\)\s*\(.*\)/mv "\2" "\1";/')
Comment by flatcap 382 weeks ago

Hmm, your sed expression is flawed. It breaks on files with leading spaces (unlikely, I know). Change the middle from "\s*" to " " (space space).

Comment by flatcap 382 weeks ago

Thanks all, I'm new to sed, so the regex looks awkward.

Some of them do not work if you have a file called:

'12" record'
