Don, they are sorted
Code:
-k1,1 -k4,4

.

T1 and T2 values can be among the set of 6 : aa,gg,tt,cc,dd,ii

Important to note that the groups with T1 and T2 values equal and groups with either/both T1 and T2 being absent must be ignored,please consider that as a preprocessing filter if you will.

Thanks for helping !

groups

groups(1)							   User Commands							 groups(1)

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
