problem to remove user from group, in fedora core 3
Thanks for your mail... problem here i am facing is i couldn't find a command using which i can remove user form a group.
In SUSE 9.2 we have the command "groupmod -R user group", but in redhar we have the groupmod only for remaning the groupname of a particular grpid.
But in redhat for adding user to a group we can use the command "usermod -G group user".. smae will also work in SUSE 9.2.....
is there any command in redhat/fedora core 3 which can remove user from a group from command line ....
but It will be problem when i want to remove a user which is a member of about 300 groups ... then i have to concat the list of groups which i don't want to change and pass it to usermod -G ... which is like more memory consuming at the time executing th command when we pass the usermod -G "grp list" user to a system() fn.....
i was looking if there is any other command in FC3 like groupmod -R which is available in SUSE Linux fro removing a user from a group..... also a command in FC3 for adding user to group like groupmod -A in SUSE

The only easy way is using a text editor to edit the /etc/passwd file. Open the file, search for the username and then delete the group from that line. Every user has his own line, i believ it something like username:UID:GID:groups:shell:home_directory.
Maybe I'm mistaken, but isn't there, where you can edit each user. Or can you only edit the users initial group...
If you want to do this by editing a file, you should edit /etc/group, not /etc/password. At the end of each group definition, there is a list of members of that group. Simply remove the username from the group.
