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

Delete all files found in directory A from directory B

Terminal - Delete all files found in directory A from directory B
for file in <directory A>/*; do rm <directory B>/`basename $file`; done

Functions: file rm
Delete all files found in directory A from directory B

This command is useful if you accidentally untar or unzip an archive in a directory and you want to automatically remove the files. Just untar the files again in a subdirectory and then run the above command e.g.

for file in ~/Desktop/temp/*; do rm ~/Desktop/`basename $file`; done


There are 3 alternatives - vote for the best!

What others think

cd ~/Desktop/temp find * -type f -exec rm ~/Desktop/temp/{} \;

@SlimG I think you meant the cd to be 'cd ~/Desktop' so in one line it would be:

find directoryA -type f -exec rm directoryB/{} \;

@jamiebullock many times you can replace a bash for loop that does a single action on some set of files with a single find command. Find lets you be very specific about the files you are searching for way beyond common shell "globbing" such as ls *.png, and then specify actions to be taken on each matching file, such as deletion, or running an arbitrary command with each match as the argument. See 'man find' for more.

tar tzf archive.tar.gz | xargs rm
Comment by log0 420 weeks and 2 days ago

@SlimG @bwoodacre Yes i'm also a big fan of find, but I periodically forget to use it! I agree it's cleaner than the for loop.

@log0 That's *very* nice

Comment by jamiebullock 420 weeks and 1 day ago

@log0 bet me to it but

ls dirA | xargs -I file rm dirB/file
