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

The 'rename' command with the first argument as "'s/\.//'" and the second argument as "" will remove the specified extension from the filenames.

Get the longest match of file extension (Ex. For 'foo.tar.gz', you get '.tar.gz' instead of '.gz')

find /some/path -type f | gawk -F/ '{print $NF}' | gawk -F. '/\./{print $NF}' | sort | uniq -c | sort -rn

If you have GNU findutils, you can get only the file name with

find /some/path -type f -printf '%f\n'

instead of

find /some/path -type f | gawk -F/ '{print $NF}'

For those files in current folder that would be shown in `ls *ext`, for some extension ext, move/rename that file removing the .ext suffix from the file name.

It uses Bash's parameter substitution, as seen in

(for analog use in prefix, see http://tldp.org/LDP/abs/html/parameter-substitution.html#PSOREX2 )

filext () { echo ${1##*.}; }

Change "sort -f" to "sort" and "uniq -ic" to "uniq -c" to make it case sensitive.

find . -type f ! -name "*.foo" -name "*.bar" -delete

This command is recursive and will delete in all directories in ".". It will find and delete all files not specified with ! -name "pattern". In this case it's file extensions. -type f means it will only find files and not directories. Finally the -delete flag ask find to delete what it matches. You can test the command by running it first without delete and it will list the files it will delete when you run it.
