Frank,
Here's a Linux-centric approach to check that a user ID exists and is
logged off. It assumes the vmcp module is loaded:
# ./checkuser.sh foo
Error: foo does not exist
# ./checkuser.sh sysmaint
# echo $?
0
# ./checkuser.sh linux191
Error: linux191 is logged on
Here's the code:
# cat checkuser.sh
#!/bin/sh
#+--------------------------------------------------------------------------+
function CPcmd()
# Run a CP command and invoke it via the vmcp module/command
# Arg1-n: the command to issue
# Return: the command's return code
#+--------------------------------------------------------------------------+
{
if [ "$verbose" = 2 ]; then // echo extra output
echo "Invoking CP command: $@"
fi
# parse output to get return code: awk -F# splits line at '#' with rc at
end
output=$(vmcp $@ 2>&1)
if [ ${#output} != 0 -a "$verbose" != 0 ]; then # echo the output
echo "$output"
fi
retVal=0
retVal=$(echo $output | grep "Error: non-zero CP" | awk -F# '{print
$2}')
return $retVal
}
#+--------------------------------------------------------------------------+
function checkID()
# Verify user ID exists and is logged off
# Arg 1: user ID to check
#+--------------------------------------------------------------------------+
{
userID=$1
verbose=0
CPcmd QUERY $userID
rc=$?
case $rc in
0) # user ID is logged on or disconnected
echo "Error: $userID is logged on"
return 1
;;
3) # user ID does not exist
echo "Error: $userID does not exist"
return 2
;;
45) # user ID is logged off - this is correct
;;
*) # unexpected
echo "Error: unexpected rc from CP QUERY $userID - $rc"
return 3
esac
verbose=1
return 0
} # checkID()
# main()
checkID $1
exit $?
Hope this helps.
