there is possible in sh to create a function who return a boolean value?
You can use true or false commands:

Code:
[root@atlas /]# true
[root@atlas /]# echo $?
0
[root@atlas /]# false
[root@atlas /]# echo $?
1
[root@atlas /]#

Or use your own function:

Code:
function f(){
exit 0
}

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
Maybe something like this?

Code:
[root@atlas /]# groups root | grep -q wheel
[root@atlas /]# echo $?
0
[root@atlas /]# groups root | grep -q asdf
[root@atlas /]# echo $?
1
[root@atlas /]#
