How can I move files with xargs on Linux?

Question

I am trying this and it's not working:

ls file_* | xargs mv {} temp/

Any ideas?

Answer 1

On OS X:

ls file_* | xargs -J {} mv {} temp/

On Linux:

ls file_* | xargs -i {} mv {} temp/

Answer 2

Use -t "specify target directoty" at mv, it should work moving files* to destination directory /temp

ex:- #ls -l file* | xargs mv -t /temp

Answer 3

find . -name "file_*" -maxdepth 0 -exec mv {} temp/ \;

find is better than ls where there might be more files than the number of program arguments allowed by your shell.

Answer 4

As suggested by @user1953864: {-i, -J} specify a token that will be replaced with the incoming arguments.

For example ls:

something.java  exampleModel.java  NewsQueryImpl.java  readme someDirectory/

Then to move all java files into the someDirectory folder with xargs would be as follows:

On Linux

ls *.java | xargs -i mv {} someDirectory/

On MacOS

ls *.java | xargs -J mv {} someDirectory

Answer 5

Another solution might be:

 for f in file_* ; do
   mv $f temp/$f
 done

The disadvantage is that it forks a new mv process for each file.
