add an exixsting user to an existing group

add an exixsting user to an existing group

[kaushal]

hi all,
	Is there a command to add an existing user to an existing group?This
will be a supplementary group for the user.He still has his main group
unchanged.I want a command instead of manually  editing the /etc/group
file.

thanks in advance.
bye.

"usermod -G xgroupy xusery" for supplementary group(s) or
"usermaod -g 4711 xusery" for a new primary group.

Have a lot of fun...

You can set the list of supplementary groups using usermod, e.g.:

	usermod -G group1,group2 user

AFAIK, there isn't a standard command to add or remove specific groups
while leaving the rest unchanged.

How about gpasswd?
gpasswd (1)          - administer the /etc/group file

"gpasswd -a user group" adds user to a supp group, "-d" removes.

OK, that seems about right.

For some reason, if you pick any one of the manual pages from the
shadow package, and follow enough of the "SEE ALSO" cross-references,
you'll eventually come across all of the other manual pages. Except
the one for gpasswd, which isn't referenced from any of them.
