>Synopsis: rm -rf "" # prints error message but should be silent
>Category: system
>Environment:
System : OpenBSD 5.9
Details : OpenBSD 5.9 (GENERIC.MP) #1888: Fri Feb 26 01:20:19 MST
2016
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
The command:
rm -rf ""
prints to STDERR:
rm: No such file or directory
but it should print nothing because of the -f flag.
Note that the command:
rm -rf nonexistant
does not print anything to STDERR.
This only happens with the empty arg "".
I compiled /usr/src/bin/rm from CURRENT and tested it, and it exhibits
the same issue.
>How-To-Repeat:
Run the command:
rm -rf ""
>Fix:
