Hi Ravinder,

Thanks for your prompt response.

This code is removing duplicate lines.
Code:
echo "$result_text" | awk '{sub(/[[:space:]]+$/,"");} !A[$0]++'

If I assign the result to a variable it's not working.


Code:
result_text1=$(echo "$result_text" | awk '{sub(/[[:space:]]+$/,"");} !A[$0]++')

echo $result_text1

Please help me.

Thanks in advance.
