Dear coreutils maintainers,
I am attaching a modified version of /usr/bin/groups which allows to suppress
errors resulting from the occurrence of artificial GIDs which are used
for authentification purposes. These errors cause difficulties e. g. in Tcl
scripts using groups via exec.
May I ask for inclusion in the standard distribution tree?
The basis used was the 5.2.1 coreutils release as used in Novell's SLES9
distribution.
Best regards
