Thread: How to do Complex Variables

hey guys,

im novice scripting gental.

okay script:

#!/bin/bash

echo "what process need?"
read process
input="ps aux |grep $process | grep -v grep | awk '{print $2}'"
kill $input

now input giving me issues when runs line $process doesnt picked up. can suggest better way of doing this?

kind regards,
fenlig

you need use command substitution. in script $input string inside double quotes. instead of

code:

input="ps aux |grep $process | grep -v grep | awk '{print $2}'"

you need

code:

input=$(ps aux |grep $process | grep -v grep | awk '{print $2}')

see here http://mywiki.wooledge.org/bashguide/specialcharacters

quote variables , use lower case variables.
