What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

Universal configuration monitoring and system of record for IT.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

can't see myself ever using this one ;)

but you get a *star* for effort!

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 275 weeks 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 275 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 275 weeks ago

60 chars, but more beautiful:

eval $(sha1sum * | sed 's/^\(\w*\)\s*\(.*\)/mv "\2" "\1";/')
Comment by flatcap 275 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 275 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'
