users and groups /etc/group parsing
Hi,
I have two little issues:
1) there is possible in sh to create a function who return a boolean value?
2)i have to verify if an user belongs to a group and i think it is needed to create a function which take two parameter and return a boolean value. in fact i have to parse /etc/group file and try to find out if my user (user taken from param1) belongs to group (group taken from param2). Any ideas? Thanks
Regards,
catalin

The command groups prints on standard output the groups to which you or the optionally specified user belong. Each user belongs to a group
specified in /etc/passwd and possibly to other groups as specified in /etc/group. Note that /etc/passwd specifies the numerical ID (gid)
of the group. The groups command converts gid to the group name in the output.
EXAMPLES
The output takes the following form:
example% groups tester01 tester02
tester01 : staff
tester02 : staff
example%
FILES
/etc/passwd
/etc/group
