Question

I need to read some values from a file with awk and then need to use the values that I read in bash.For example the structure of file will be

NICE = -13

LATENCY= 100

WMEM= 4 

I need to read the values -13, 100 and 4 from the file with awk and then use them in bash. The structure of script will be;

#!/bin/bash

awk'{}'

and then use the values here in script

Answer 1

If your input is in data.txt then try running the following command inside your script:

values=`cat data.txt | awk -F '=' '{print $2}' | xargs`

values variable will then contain: -13 100 4
