Full Discussion: members in a group
Operating Systems Linux members in a group Post 302311753 by sewdan on Wednesday 29th of April 2009 12:33:09 PM

To explain my previous post,
groups user
will display the groups of a single user.

Using the awk command from the last posting will run groups for each user found in the /etc/passwd file.
-F: uses : as the field separator,
%1 is the first field in the file,
`` runs the output from the awk command
2>nul hides the err output from the command
