# nu user=xxx os=unix pgroup=xxxxx
i used below line to get the pgroup name.
--> PGRP=$(echo "$@" |cut -f2 -d'=')

posix_spawnattr_setpgroup
POSIX_SPAWNATTR_GETPGROUP(3) BSD Library Functions Manual POSIX_SPAWNATTR_GETPGROUP(3)
NAME
posix_spawnattr_getpgroup, posix_spawnattr_setpgroup -- get and set the spawn-pgroup attribute of a spawn attributes object
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <spawn.h>
int
posix_spawnattr_getpgroup(const posix_spawnattr_t *restrict attr, pid_t *restrict pgroup);
int
posix_spawnattr_setpgroup(posix_spawnattr_t *attr, pid_t pgroup);
DESCRIPTION
The posix_spawnattr_getpgroup() function obtains the value of the spawn-pgroup attribute from the attributes object referenced by attr.
The posix_spawnattr_setpgroup() function sets the spawn-pgroup attribute in an initialized attributes object referenced by attr.
The spawn-pgroup attribute represents the process group to be joined by the new process image in a spawn operation (if POSIX_SPAWN_SETPGROUP
is set in the spawn-flags attribute). The default value of this attribute is zero.
RETURN VALUES
The posix_spawnattr_getpgroup() and posix_spawnattr_setpgroup() functions return zero.
SEE ALSO
posix_spawn(3), posix_spawnattr_destroy(3), posix_spawnattr_init(3), posix_spawnp(3)
STANDARDS
The posix_spawnattr_getpgroup() and posix_spawnattr_setpgroup() functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
The posix_spawnattr_getpgroup() and posix_spawnattr_setpgroup() functions first appeared in FreeBSD 8.0 and imported for NetBSD 6.
