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/

You can sign-in using OpenID credentials, or register a traditional username and password.

First-time OpenID users will be automatically assigned a username which can be changed after signing in.


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.

User: depesz
Functions: rename

As long as you have perl based rename. You can check:

=$ rename --help

Unknown option: help

Usage: rename [-v] [-n] [-f] perlexpr [filenames]

That's the good one.

sed -i 's/ /-/g' *

Know a better way?

I meant to say filename I wasn't paying enough attention. Thank you for pointing this out :)

Comment by RaymondCrandall 227 weeks and 3 days ago

in the link I provided I made it clear what my intentions were, but I guess I should have proof read.

Comment by RaymondCrandall 227 weeks and 3 days ago

You could use (without tr)

for f in * ; do mv "$f" "${f// /-}" ; done

Note that it doesn't remove any other special character.

Cool! Is there a name for ${...} notation? I would like to read more about it.

Comment by RaymondCrandall 227 weeks and 2 days ago
