Hi I just want again to ask for help on what command to use to vlookup f1 group name in "/etc/group" matching f3 of it to "/etc/passwd" f4. I do need to display group name in the output of /etc/passwd without using awk or NR==FNR command. thank you

group
GROUP(5) BSD File Formats Manual GROUP(5)NAME
group -- format of the group permissions file
DESCRIPTION
The file </etc/group> consists of newline separated ASCII records, one per group, containing four colon ':' separated fields. These fields
are as follows:
group Name of the group.
passwd Group's encrypted password.
gid The group's decimal ID.
member Group members.
The group field is the group name used for granting file access to users who are members of the group. The gid field is the number associ-
ated with the group name. They should both be unique across the system (and often across a group of systems) since they control file access.
The passwd field is an optional encrypted password. This field is rarely used and an asterisk is normally placed in it rather than leaving
it blank. The member field contains the names of users granted the privileges of group. The member names are separated by commas without
spaces or newlines. A user is automatically in a group if that group was specified in their /etc/passwd entry and does not need to be added
to that group in the /etc/group file.
INTERACTION WITH DIRECTORY SERVICES
Processes generally find group records using one of the getgrent(3) family of functions. On Mac OS X, these functions interact with the
DirectoryService(8) daemon, which reads the /etc/group file as well as searching other directory information services to determine groups and
group membership.
FILES

The passwd(1) command does not change the group passwords.

A group file format appeared in Version 6 AT&T UNIX.
