Shell: Functions

In this tutorial I will show you how to work with functions.

Define Function

You return 0 for success and 1 for failure

function test()
{
    return 0
}

Call function with no arguments

test

Call function with arguments

val1='test'
val2='test2'
test $val1 $val2

Call function with arguments that have spaces in the value

val1='test'
val2='test2 test23'
test "${val1}" "${val2}"
