lineNumber is global variable because its in the begin section. For each line lineNumber is incremented by 1. then I just made a simple printf statement printing the line count and the entire line. If you save the filename as myscript you can execute the program like this. Remember you must my shell scripts executable chmod 755 myscript

Code:

#!/bin/bash

./myscript /etc/passwd

If you want to save the output just simply do this.

./myscript /etc/passwd > numberOutput.txt

awk '

BEGIN{

    lineNumber=0;

}

{ 

    lineNumber++;

    printf("%d. %s\n",lineNumber, $0);          

}

' "$1"

Of course you can use cat in BASH to do the exact same thing. Each line is tabbed at the beginning though.

Code:

cat -n /etc/passwd

This is almost the same as in C++.
It is interesting how it outputs it in a file !
