Script explanation:
(#!/bin/bash): #! is a conventional marker that tells the system which interpreter should be used to execute the script.
/bin/bash means the script is executed using the default Bash shell.
Here, a for loop is needed to iterate over the found GIDs (group IDs) for processing.
(awk -F':' '{print $3}' /etc/group):
awk is used to split and process text.
-F specifies the field separator.
":" indicates that the colon is used as the delimiter.
{print $3} prints the third field (the group ID).
