How can i read specific line and specific field using Bash?

Question

I have this file and i want to only get the value of testme= So that i can do another action. But this throws lots of lines and actually cant yet make it work.

1. test.sh

#!/bin/bash
for i in $(cat /var/tmp/test.ini); do
  # just one output i need: value1
  grep testme= $i 
done

2. /var/tmp/test.ini

; comments
testme=value1
; comments
testtwo=value2

Answer 1

How about

#!/bin/bash

grep 'testme=' /var/tmp/test.ini | awk -F= '{ print  $2 }'

or alternatively just using bash

#!/bin/bash

regex='testme=(.*)'

for i in $(cat /var/tmp/test.ini);
do
    if [[ $i =~ $regex ]];
    then
        echo ${BASH_REMATCH[1]}
    fi
done
