My real program is working correctly.
These script are just shown to explain the question.
The code by itself is not important.
My real problem is the coding line
If the last part of a pipe return no error and if a previous part of a pipe return one error (say 123)
1°) What is the value of $RETURN_CODE 0 or 123
2°) Is the return code set to 0 ( if not, I have a problem somewhere in my code)
how to get the error code (123) for the global result which must be considered as failing.
I apologize if I have already posted this query. I scanned back quite a few pages but could not find such a query.
If my perl code contains "exit(33)" how can I get that value in bash for use in a "if" statement.
Thanks,

schedctl
SCHEDCTL(8) BSD System Manager's Manual SCHEDCTL(8)NAME
schedctl -- control scheduling of processes and threads
SYNOPSIS
schedctl [-A cpus] [-C class] [-P pri] [-t lid] -p pid | command
DESCRIPTION
The schedctl command can be used to control the scheduling of processes and threads. It also returns information about the current schedul-
ing parameters of the process or thread. Only the super-user may change the scheduling parameters. schedctl can also be used to start a new
command using the specified parameters.
Available options:
-A cpus Set of the processors on which process or thread should run, that is, affinity. Processors are defined as numbers (starting from
zero) and separated by commas. A value of -1 is used to unset the affinity.
-C class Scheduling class (policy), one of:
SCHED_OTHER Time-sharing (TS) scheduling policy. The default policy in NetBSD.
SCHED_FIFO First in, first out (FIFO) scheduling policy.
SCHED_RR Round-robin scheduling policy.
-P pri Priority for the process or thread. Value should be in the range from SCHED_PRI_MIN (0) to SCHED_PRI_MAX (63). Setting of prior-
ity for the process or thread running at SCHED_OTHER policy is not allowed.
-p pid The target process which will be affected. If the process has more than one thread, all of them will be affected.
If -p is not given, a command to execute must be given on the command line.
-t lid Thread in the specified process. If specified, only this thread in the process will be affected. May only be specified if -p is
also given.
EXAMPLES
Show scheduling information about the process whose ID is ``123'':
# schedctl -p 123
Set the affinity to CPU 0 and CPU 1, policy to SCHED_RR, and priority to 63 for thread whose ID is ``1'' in process whose ID is ``123'':
# schedctl -p 123 -t 1 -A 0,1 -C SCHED_RR -P 63
Run the top(1) command with real-time priority:
# schedctl -C SCHED_FIFO top

The schedctl command first appeared in NetBSD 5.0.
