How to read a file line by line with Bash

Sometimes you want to do actions per line instead of the complete file at once.

Here is an example that you can use to read the file line by line.

#!/bin/bash
run_cmd_file() {
    while read line
    do
        chr=${line:0:1}
        case $chr in 
            "#" )  # ignore commented lines
                ;;      
            *   )   
                echo line[$line]"
                ;;      
        esac    
    done < $2
}
 
run_cmd_file filename

When you’re my age, you know that the end is in sight. How do you handle it? You live for the moment. The past is gone and the future isn’t here yet. And you ain’t gonna change it, no matter what you think. And so the most obvious thing to do is right now.
