groups: command not found [closed]

Question

I'm getting the following error after logging in:

Last login: Thu May 30 15:25:49 2013 from 
-bash: groups: command not found

xxx@Dogbert:~$ /usr/bin/groups
-bash: /usr/bin/groups: Permission denied

xxx@Dogbert:~# su -

root@Dogbert:~# ls -la /usr/bin/groups 

-rwxr-xr-x 1 root root 26180 Mai 28 22:21 /usr/bin/groups

Any ideas?

Answer 1

1 easy possibility (before further infos from you):

• At the point where your login script(s) uses "groups" (without saying "/usr/bin/groups"), the current $PATH doesn't yet contain /usr/bin ?
