One small addition: Having the shell expand the wildcards can lead to a command line that is too long. Then you get something like: bash: parallel: Argument list too long So the bullet proof and guaranteed safe way (with no exceptions) is to do: printf '%s\0' *.log | parallel -0 do_stuff This deals correctly with: * File names containing newline (\n) * More file names than fit on the command line https://www.gnu.org/software/parallel/man.html#EXAMPLE:-Inserting-multiple-arguments /Ole
