Consider adding a counter, bump it up on every line, and print the counter with every line. Also note fixes to set log_file, update to read command. log_file=”/home/user/log.txt” line_no=0 while read -r line do line_no=$((line_no+1)) printf “%d. %s\n” $line_no “$line” done < “$log_file” One alternative to consider is to call the nl utility, which performs … Read more
