[PATCH] commands: rm: add -f option to ignore nonexistent files

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



rm supports multiple arguments, but will stop at the first nonexistent
file and print an error message that can't be silenced. Mimic other
implementations and implement -f for silently ignoring nonexistent files.
