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

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?

If you can do better, submit your command here.

What others think

in a file != in a filename

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

Comment by RaymondCrandall 347 weeks and 6 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 347 weeks and 6 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 347 weeks and 5 days ago

^Try "parameter expansion".
