name
() {
commands
; }
Define
name
as a function. Syntax can be written on
one line or across many. Since the Bourne shell has no
aliasing capability, simple functions can serve as aliases.
The Korn shell provides the
function
command, an alternate
form that works the same way.
$
count () {
>
ls | wc -l
>
}
When issued at the command line,
count
will now display the
number of files in the current directory.
