bash Quick Reference

Name

name()

Synopsis

name () { commands; }

Define name as a function. POSIX syntax. The function definition can be written on one line or across many. You may also provide the function keyword, an alternate form that works similarly. See the earlier section Functions.

Example

$ count (  ) {
>     ls | wc -l
> }

When issued at the command line, count now displays the number of files in the current directory.
