Please post the command you typed and the output your received followed by the expected output after filtering or processing. We can gather from your posts that your are monitoring print queues in some detail but need to know what information you need from AIX to perform your role.

ksh - can use read with pipe:

lpstat | grep "^abxxxxb1 " | read queue dev status somefields

[ "$queue" = "" ] && print "no status for abxxxxb1" >&2 && exit 1

[ "$status" != "DOWN" ] && print "abxxxxb1 ok" && exit 0

print "abxxxxb1 is down"

General sh version to use read:

read queue dev status somefields <<EOF
$(lpstat | grep "^abxxxxb1 " )
EOF
