[SOLVED] How to get parent pid from script?

Issue

./tesh.sh 192.168.1.10 elastic01

# this is script
ip=$1
node=$2

pid=`ps -ef | grep $node | grep -v "grep" | awk '{print \$2}'`

echo $pid

run this script output:
2234 (I want to get)
2313
3241

Solution

If you want just the top entry, use

awk 'NR==1 { print $2 }'

Process only the first line with NR==1 and print only the second space delimited field.
