First off, there are several syntactical problems in your script:
I don't know what this is supposed to do, but most probably it won't do it, whatever "it" is.
Second, i don't know which system you are working on. If it is some Linux or Linuxoid system you can simply get all the primary groups of all the users by reading field 4 in the file /etc/passwd. If you need the groups name just refer to /etc/group for a name-GID relation. See the code-snippet below:
The reason why your code might have failed is not clear. One possibility is that you counted users more than one times: suppose user ONE has groups A, B, C, D, user B has groups "A, C, D". Per your algorithm you would find user account B three times and count it for three distinct users. To avoid this you will have to make your list with users unique by filtering out all the doubles, probably by filtering the fnal list through "sort -u" or something such.
When users login, they are directed to menu (aix script). The menu enables the user to choose an environment to work in. Each environment has a different group id. When a user chooses a menu option, I want to change his primary group to that specific environment's group id. Is this at all possible... (3 Replies)
Is there a command or better combination of cmds that will give me the list of Unix users in a particular Unix group whether their primary group is that group in question (information stored in /etc/passwd) or they are in a secondary group (information stored in /etc/group).

Requirements:

2) Login into each server and check whether perticular... (1 Reply)
Hi,
I have a file with usernames, and the comment section, e.g :
Data removed by request of sanchitadutta91, 20 May 2020
I need to add these users into a server. Is it possible to use a script to create the users, together with the comment ?

lslogins
LSLOGINS(1) User Commands LSLOGINS(1)NAME
lslogins - display information about known users in the system
SYNOPSIS
lslogins [options] [-s|-u[=UID]] [-g groups] [-l logins]
DESCRIPTION
Examine the wtmp and btmp logs, /etc/shadow (if necessary) and /etc/passwd and output the desired data.
The default action is to list info about all the users in the system.
OPTIONS
Mandatory arguments to long options are mandatory for short options too.
-a, --acc-expiration
Display data about the date of last password change and the account expiration date (see shadow(5) for more info). (Requires root
privileges.)
--btmp-file path
Alternate path for btmp.
-c, --colon-separate
Separate info about each user with a colon instead of a newline.
-e, --export
Output data in the format of NAME=VALUE.
-f, --failed
Display data about the users' last failed login attempts.
-G, --supp-groups
Show information about supplementary groups.
-g, --groups=groups
Only show data of users belonging to groups. More than one group may be specified; the list has to be comma-separated.
Note that relation between user and group may be invisible for primary group if the user is not explicitly specify as group member
(e.g. in /etc/group). If the command lslogins scans for groups than it uses groups database only, and user database with primary GID
is not used at all.
-h, --help
Display help information and exit.
-L, --last
Display data containing information about the users' last login sessions.
-l, --logins=logins
Only show data of users with a login specified in logins (user names or user IDS). More than one login may be specified; the list
has to be comma-separated.
-n, --newline
Display each piece of information on a separate line.
--noheadings
Do not print a header line.
--notruncate
Don't truncate output.
-o, --output list
Specify which output columns to print. Use --help to get a list of all supported columns.
-p, --pwd
Display information related to login by password (see also -afL).
-r, --raw
Raw output (no columnation).
-s, --system-accs
Show system accounts. These are by default all accounts with a UID below 1000 (non-inclusive), with the exception of either nobody
or nfsnobody (UID 65534). This hardcoded default maybe overwritten by parameters SYS_UID_MIN and SYS_UID_MAX in the file
/etc/login.defs.
--time-format type
Display dates in short, full or iso format. The default is short, this time format is designed to be space efficient and human
readable.
-u, --user-accs
Show user accounts. These are by default all accounts with UID above 1000 (inclusive), with the exception of either nobody or nfs-
nobody (UID 65534). This hardcoded default maybe overwritten by parameters UID_MIN and UID_MAX in the file /etc/login.defs.
-V, --version
Display version information and exit.
--wtmp-file path
Alternate path for wtmp.
-Z, --context
Display the users' security context.
-z, --print0
Delimit user entries with a nul character, instead of a newline.
NOTES
The default UID thresholds are read from /etc/login.defs.
EXIT STATUS
0 if OK,
1 if incorrect arguments specified,
2 if a serious error occurs (e.g. a corrupt log).
