Question

I’m not experienced with shell scripting. I made this:

#!/bin/bash

function hac() {
    echo "test: $1"
    javac $1.java && java $1
}

hac SquareDriver

So I have SquareDriver.class in the working directory and this works when I call
./scriptname.sh

However, I would like to make it so I could just call hac filename on the command line and it would execute the function from within this file.

How can I do this?

Answer 1

Put the function definition in your ~/.bashrc. This will make hac available in all your terminal sessions.
