Syntax: Functions and Function Calls

Defining a Function

function <function-name> { <statements> }
function <function-name> ( <argument-list> ) { <statements> }

The function statement associates an optional argument‑list and a set of statements with function‑name.

The argument-list specifies one or more arguments. These arguments are local to the function's statement block, and are accessed as a variable.

Function Examples

function helloworld {
  print 'hello world';
}

function hello (arg) {
  # remember to use double quotes
  print "hello ${arg}";
}

Calling a Function

A function with no arguments is simply called by using the function name.

helloworld;

A function with arguments is passed a list as the argument parameters.

hello [ 'to you' ];

set a [ 'to them' ];
hello ${a};
