I'm just adding this more complex example to highlight how mmv is affected, not just by the number of files it is operating on directly, but by the number of files in the current directory.
# BEGIN SCRIPT mkdir -p mmv-bug.d/mmv-bug.d cd mmv-bug.d/mmv-bug.d find -maxdepth 1 | grep -c . seq 1 2 | sed 's/.*/A-Random-File-&.touch/' | xargs touch mmv -n "*touch" "#1touche" seq -w 1 10 | sed 's/.*/Empty-Dir-&.d/' | xargs mkdir find -maxdepth 1 | grep -c . mmv -n "*touch" "#1touche" cd .. find | grep -c . seq 1 2 | sed 's/.*/A-Random-File-&.touch/' | xargs touch mmv -n "*touch" "#1touche" # END SCRIPT Running this should produce the following output: 1 A-Random-File-1.touch -> A-Random-File-1.touche A-Random-File-2.touch -> A-Random-File-2.touche 13 realloc(): invalid pointer Aborted 14 A-Random-File-1.touch -> A-Random-File-1.touche A-Random-File-2.touch -> A-Random-File-2.touche -- Sent via Swisscows.email. My mails are safe. And yours?
