Functions

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

Batch file suffix renaming

Terminal - Batch file suffix renaming
rename -n "s/-.*//" *

Batch file suffix renaming

of course, replace the "-" after / by the character you wish. a dot must by protected by a backslash, as it is a regexp. it's the same result as the command proposed. but if there is more than a dash in the name, only the part before the first dash is kept... so that's not an "extension renaming" command.

Alternatives

There is 1 alternative - vote for the best!

Terminal - Alternatives
for i in *; do j=`echo $i | cut -d "-" -f1`; j=$j; mv $i $j; done

Functions: cut mv

Renames files eliminating suffix, in this case everything after "-" is cutted. Just change "-" with the character you need.

mmv "*-*.mp3" "#1.mp3"

-1

replace the "-" by the character you wish. If you have multiple extentions, like jpef, jpg and JPG you could use

mmv "*-*.*" "#1.#3"

Know a better way?

If you can do better, submit your command here.

What others think

The 'rename' command used by pepin is Larry Wall's Perl script of that name. It is not the 'rename' command that is part of the 'util-linux-ng' package. On my own systems, I have renamed Larry's script to 'sren', just to be clear on the distinction. The Linux package command seems to me to be of limited value.
