allow or not script

hi guys

I am working on a menu...
and the menu has some options like check status for services (gmonitor group) or stop - start - restart those same services (gadmin group)

as you see there are 2 main groups gmonitor for monitoring and gadmin for restart - stop - start services

so checking command groups

Code:

#groups root

root : root bin daemon sys adm disk wheel ivmgr httpd gadmin



#groups cgonza

cgonza : cgonza testing gmonitor

basically I want to read the output from groups command and atfer that

if group gadmin is found allow the user to restart services and if gmonitor group is found deny access to restart services

the point is I don't know how to get that groupvar

Code:

if [ "$groupvar" == "gadmin" ]

        then

        restart services options

      else

        echo "... you are not allowed to ..."

thanks a lot

You don't need the string, using the exit value like:

Code:

groups 2>/dev/null|grep -q gmonitor; case "$?" in 

0) restart services options;; 

*) echo "... you are not allowed to ...";; 

# et cetera

should do, or if you still want to "if then" try:

Code:

if [ "${groupvar}" = "${groupvar//gadmin/}" ]; then

 echo "... you are not allowed to ..."

else

 restart services options

# et cetera
