I just gave the OP a command that works. I hadn't expected it to kick off a discussion, nor to have to justify it. But: axis!david 08:55:22 ~ $ grep -e '^adm' -e '^unlock' /etc/group adm:x:4:david unlock:x:1010: axis!david 08:55:47 ~ $ grep -e '^adm' -e '^unlock' /etc/group adm:x:4:david,unlock unlock:x:1010: axis!david 08:56:40 ~ $ axis 08:51:11 ~# addgroup unlock adm Adding user `unlock' to group `adm' ... Adding user unlock to group adm Done. axis 08:56:28 ~# Or, if you prefer it in a time sequence: axis!david 08:55:22 ~ $ grep -e '^adm' -e '^unlock' /etc/group adm:x:4:david unlock:x:1010: axis!david 08:55:47 ~ $ grep -e '^adm' -e '^unlock' /etc/group axis 08:51:11 ~# addgroup unlock adm Adding user `unlock' to group `adm' ... Adding user unlock to group adm Done. axis 08:56:28 ~# axis!david 08:55:47 ~ $ grep -e '^adm' -e '^unlock' /etc/group adm:x:4:david,unlock unlock:x:1010: axis!david 08:56:40 ~ $ Buried in there is "addgroup unlock adm", where adm is the well-known group, and unlock is the user whose sole function is to lock and unlock /home partitions on my systems. Cheers, David.
