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.

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 320 weeks and 2 days ago

Or use:

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

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
