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

NAME
groups - print group membership of user SYNOPSIS
groups [user]... DESCRIPTION
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 ATTRIBUTES
