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

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

User: KlfJoat
Functions: find rename

Everyone wants to take spaces out of filenames. Forget that. I want to put them back in. We've got tools and filesystems that support spaces, they look better, so I'm going to use them.

Because of how find works I find I need to run this multiple times, if it's renaming subdirs. But it can be re-run without issues.

I got this version of the command from a comment in this underscore-generating command. http://www.commandlinefu.com/commands/view/760/find-recursively-from-current-directory-down-files-and-directories-whose-names-contain-single-or-multiple-whitespaces-and-replace-each-such-occurrence-with-a-single-underscore. All I did was change the regex.

sed -i "s/\s*/ /g;s/\s*$//" input_file
sed -i "s/\(\x09\{1,\}\)\|\( \{1,\}\)/ /g;s/\(\x09\{1,\}$\)\|\( \{1,\}$\)//g" brisati.txt

Functions: sed

This command does the following:

- converts any sequence of multiple spaces/tabs to one space only

- completely removes any space(s)/tab(s) at the end of each line

(If spaces and tabs are mixed in a sequence i.e. [tab][tab][space][tab], you have to execute this command twice!)

find . -type f -name \*.php | while IFS="" read i; do expand -t4 "$i" > "$i-"; mv "$i-" "$i"; done

User: flatcap
Functions: expand find mv read

Recursively find php files and replace tab characters with spaces.


"\*.php" -- replace this with the files you wish to find

"expand" -- replace tabs with spaces (use "unexpand" to replace spaces with tabs)

"-t4" -- tabs represent 4 spaces

Note: The IFS="" in the middle is to prevent 'read' from eating leading/trailing whitespace in filenames.

find $DIR -name *.php -exec vim -u NONE -c 'set ft=php' -c 'set shiftwidth=4' -c 'set tabstop=4' -c 'set noexpandtab!' -c 'set noet' -c 'retab!' -c 'bufdo! "execute normal gg=G"' -c wq {} \;

Functions: find vim

The sample command searches for PHP files replacing tabs with spaces.

-u NONE # don't use vimrc

Instead of


one may pass

retab! 4

for instance.

rsync [options] -- * target

User: l0b0
Functions: rsync

Using the double dash before the source and target makes the command work fine with weird filenames.

ls -Q * | xargs -p rm
2010-01-27 02:46:49
User: temp_reg
Functions: ls xargs

ls -Q will show the filenames in quotes. xargs -p rm will print all the filenames piped from ls -Q and ask for confirmation before deleting the files.

without the -Q switch, if we have spaces in names, then the files won't be deleted.
