I am facing a problem with my script.
I have to found the primary group of users .
So first I selected all the groups and users register from a specific user : ONE
Then I am making a file with all groups attached to the user : ONE
Then I am making a file with all users from each group of that user : ONE Then for each user I have to found his primary group
Ex : Groups of USER ONE
GRP1 ::111 :ONE,TWO,THRE
GRP2 ::2848 :SIX ;ONE,SEVEN
and so one
Here is the script that i have writen :
My problem is the number of users listed is by far beyond of the userlist.
I've got 151 users but at the end the list contain 298 entries .... I can't find what is wrong.
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).

Maybe with groups cmd ? (first group name in line, is the primary group)
thx for help. (2 Replies)
Hi Experts,
I am new to scripting. We have around 400 Linux servers in our environment. I want to add a new user to a perticular group on all the servers using SSH.
Requirements:
1) Need to take the server names from a text file.
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 ?
From the commandline to add one user, the... (2 Replies)

unbuffer
UNBUFFER(1) General Commands Manual UNBUFFER(1)NAME
unbuffer - unbuffer output
SYNOPSIS
unbuffer program [ args ]
INTRODUCTION
unbuffer disables the output buffering that occurs when program output is redirected from non-interactive programs. For example, suppose
you are watching the output from a fifo by running it through od and then more.
od -c /tmp/fifo | more
You will not see anything until a full page of output has been produced.
You can disable this automatic buffering as follows:
unbuffer od -c /tmp/fifo | more
Normally, unbuffer does not read from stdin. This simplifies use of unbuffer in some situations. To use unbuffer in a pipeline, use the
-p flag. Example:
process1 | unbuffer -p process2 | process3
CAVEATS
unbuffer -p may appear to work incorrectly if a process feeding input to unbuffer exits. Consider:
process1 | unbuffer -p process2 | process3
If process1 exits, process2 may not yet have finished. It is impossible for unbuffer to know long to wait for process2 and process2 may
not ever finish, for example, if it is a filter. For expediency, unbuffer simply exits when it encounters an EOF from either its input or
process2.
In order to have a version of unbuffer that worked in all situations, an oracle would be necessary. If you want an application-specific
solution, workarounds or hand-coded Expect may be more suitable. For example, the following example shows how to allow grep to finish pro-
cessing when the cat before it finishes first. Using cat to feed grep would never require unbuffer in real life. It is merely a place-
holder for some imaginary process that may or may not finish. Similarly, the final cat at the end of the pipeline is also a placeholder
for another process.
$ cat /tmp/abcdef.log | grep abc | cat
abcdef
xxxabc defxxx
$ cat /tmp/abcdef.log | unbuffer grep abc | cat
$ (cat /tmp/abcdef.log ; sleep 1) | unbuffer grep abc | cat
abcdef
xxxabc defxxx
$
BUGS
The man page is longer than the program.
