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

Move large numbers of files

Terminal - Move large numbers of files
for f in *; do mv $f <target_path>; done;

Move large numbers of files

In my job I often have to deal with moving 100,000 files or more. A mv won't do it because there are too many. This will move everything in the current directory to the target path.


There is 1 alternative - vote for the best!

What others think

That will be _very_ slow. I suggest you:

find -maxdepth 1 | xargs mv --target=destdir

find -maxdepth 1

matches '.' ... so you'll get

mv: cannot move `.' to `/home/rpolli/.local/.': Device or resource busy

find -maxdepth 1 -mindepth 1 | xargs mv --target=destdir

Comment by pixelbeat 415 weeks and 1 day ago

Or use:

find /dir/with/largefiles -type f -name "*.gz" -exec mv {} /targetdir \;

Comment by cow 415 weeks ago

wtf. Why not

mv * <target_path>

It does exactly what it is supposed to do.

Ok sorry for my last message. I didn't read the description carefully ("A mv won't do it because there are too many.")

However mv only works perfectly well with 200 000 files under debian and cygwin.

Which system are you using ? Is the problem related to the size of the file ?

It sounds strange to my that gnu mv would actually need a patch.

After a bit of investigation:

gnu mv can handle the max size of a signed int.

However the number of arguments that can be given to a command is limited by ARG_MAX:


There's no such limitation since linux 2.6.23
