it seems the above APIDS variable was created only to gather IPs. and then it is fed to the real command in the AllProcs variable.
can this be shortened into one command and also in an efficient way?
So it looks to me that you are trying to list all the processes with the PID or PPID of "${gpid}"
Consider this:
This will list the PIDs of all processes whose PPID is the gpid. If you have it,
will do the same but give them in a comma-delimited list. So perhaps this?
If you don't have pgrep then you have to turn the output of my earlier ps command into a comma-delimited list and use that.
I am sending a kill comand to kill a process inside a SH script but I don`t want the user to notice it so I donīt want the message "1222 killed" to appear.
I`ve tried to redirect the standard output to /dev/null 2>&1 and also tried to use "nohup" but none of them was succesfull.

Sometimes we need a single instance of a script to run at a time. Meaning, the script itself should detects whether any instances of himself are still running and act accordingly.
When multiple instances of one script running, it’s easy to cause problems. I’ve ever seen that about 350 instances... (4 Replies)

pkill
PKILL(1) BSD General Commands Manual PKILL(1)NAME
pkill -- find or signal processes by name
SYNOPSIS
pgrep [-filnvx] [-d delim] [-G gid] [-g pgrp] [-P ppid] [-s sid] [-t tty] [-U uid] [-u euid] pattern ...
pkill [-signal] [-filnvx] [-G gid] [-g pgrp] [-P ppid] [-s sid] [-t tty] [-U uid] [-u euid] pattern ...
prenice [-l] priority pattern ...
DESCRIPTION
The pgrep command searches the process table on the running system and prints the process IDs of all processes that match the criteria given
on the command line.
The pkill command searches the process table on the running system and signals all processes that match the criteria given on the command
line.
The prenice command searches the process table on the running system and sets the priority of all processes that match the criteria given on
the command line.
The following options are available for pkill and pgrep:
-d delim Specify a delimiter to be printed between each process ID. The default is a newline. This option can only be used with the pgrep
command.
-f Match against full argument lists. The default is to match against process names.
-G gid Restrict matches to processes with a real group ID in the comma-separated list gid.
-g pgrp Restrict matches to processes with a process group ID in the comma-separated list pgrp. The value zero is taken to mean the
process group ID of the running pgrep or pkill command.
-i Ignore case distinctions in both the process table and the supplied pattern.
-l Long output. Print the process name in addition to the process ID for each matching process. If used in conjunction with -f,
print the process ID and the full argument list for each matching process.
-n Match only the most recently created process, if any.
-P ppid Restrict matches to processes with a parent process ID in the comma-separated list ppid.
-s sid Restrict matches to processes with a session ID in the comma-separated list sid. The value zero is taken to mean the session ID of
the running pgrep or pkill command.
-t tty Restrict matches to processes associated with a terminal in the comma-separated list tty. Terminal names may be specified as a
fully qualified path, in the form 'ttyXX', or 'pts/N', (where XX is any pair of letters, and N is a number), or the shortened forms
'XX' or 'N'. A single dash ('-') matches processes not associated with a terminal.
-U uid Restrict matches to processes with a real user ID in the comma-separated list uid.
-u euid Restrict matches to processes with an effective user ID in the comma-separated list euid.
-v Reverse the sense of the matching; display processes that do not match the given criteria.
-x Require an exact match of the process name, or argument list if -f is given. The default is to match any substring.
-signal A non-negative decimal number or symbolic signal name specifying the signal to be sent instead of the default TERM. This option is
valid only when given as the first argument to pkill.
The -l flag is also availale for prenice.
Note that a running pgrep or pkill process will never consider itself or system processes (kernel threads) as a potential match.
EXIT STATUS
pgrep, pkill, and prenice return one of the following values upon exit:
0 One or more processes were matched.
1 No processes were matched.
2 Invalid options were specified on the command line.
3 An internal error occurred.

pkill and pgrep first appeared in NetBSD 1.6. They are modelled after utilities of the same name that appeared in Sun Solaris 7.
prenice was introduced in NetBSD 6.0.
