Syntax
[function] function-name() { ... }
The "function" keyword is optional.
Arguments
The function does not declare its arguments in the signature. They are available in the function's body as $1, $2, etc.
Return Values
A bash function does not return a value, it only allows to set an exit status, which is a numerical value. 0 indicates success and a non-zero value indicates failure. The exit status is declared with the "return" keyword:
function f() { ... return 0 }
