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

Remove all files previously extracted from a tar(.gz) file.

Terminal - Remove all files previously extracted from a tar(.gz) file.

Functions: rm tar xargs
Remove all files previously extracted from a tar(.gz) file.


There are 5 alternatives - vote for the best!

Terminal - Alternatives
tar -tf <file.tar.gz> | parallel rm

Functions: tar

xargs deals badly with special characters (such as space, ' and "). To see the problem try this:

touch important_file

touch 'not important_file'

ls not* | xargs rm

Parallel https://savannah.nongnu.org/projects/parallel/ does not have this problem.

for i in $(tar -tf <file.tar.gz>); do rm $i; done;

Functions: rm tar

Remove annoying improperly packaged files that untar into the incorrect directory.

Example, When you untar and it extracts hundreds of files into the current directory.... bleh.

Know a better way?

If you can do better, submit your command here.

What others think

None of these alternatives is perfect. If one of the tar's directories has other files (like /usr/share/man), the 'rm -r' from alternative 1 will end up erasing the whole directory. And alternative 2 just does not remove directories.

My take:

tar tf <file.tar.gz> | sort -r | while read file; do if [ -d "$file" ]; then rmdir "$file"; else rm -f "$file"; fi; done

--> This command will spit a few error messages if there are already files on some directories, etc., but it will work OK and safe and will erase files and directories in the right order (files first, respective directories afterwards).

many times people use * to build their archives which cause me some time stamp way to do this ... why not interrogate the archive ... Usually *nix users behave and put stuff in a folder then tar it up ... but most of the time when I see * archive it's .zip file ... this this inspired me to come up with this one:

unzip -lt foo.zip | grep testing | awk '{print $2}' | xargs rm -r

use pipe | while read a; instead of xargs. it happened to me to have too many entry to finish the buffer using xargs
