linux - Prevent * to be expanded in the bash script

Linux bash script:

#!/bin/bash

function Print()
{
    echo $1
}

var="*"
Print $var

Execution results:

[email protected]:~/tmp$ ./sample-script 
sample-script

* is expanded to the list of files, which is actually script itself. How can I prevent this and see actual variable value? In general case, var can be more complicated than *, for example: home/alex/mydir/*.

you need to escape your variables, too:

Print "$var"

And in your function:

echo "$1"
