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

Note the g for global in the perl expression; without it, only the first occurrence in the name would be replaced.

hah. comment fail.

Using the null char to delimit files is generally preferable, and using xargs is more efficient because it causes less execs on large trees. You can use -n with xargs to specify how many parameters you want to pass:

find . \( -type f -o - type d \) -print0 |xargs -0 rename 's/\s+/_/g'

oh, and FWIW, this is a google interview question (or was at one time), where you're asked to explain how you'd do a bulk rename of files with spaces in them because a vendor provided a bunch of image files for a catalog with hideous file names.

Comment by hso 396 weeks and 6 days ago

No need for the -name "*", find will recursively list all files by default.

Also, the suggestion for xargs is a good one, but also not needed with find's '+' operator.

find . -exec rename 's/\s+/_/g' {} +

The rename command didn't work as expected from me. I found out I have a different version of the rename command in my distro, Arch Linux. I needed the Debian version of rename, prename in Arch.
