Deferred Commands

You can defer the execution of a command or group of commands until the end of the program or function. Useful for clean up commands.

The defer keyword marks the given command, group or sub-shell to be deferred until the end of the program or function.

Format:

defer command

For example:

defer echo foo
echo bar

Will output:

bar
foo

You are not limited to simple commands, you're free to use groups and sub-shells as well:

Defer a group:

defer {
	echo foo
	echo bar
}

echo baz

Defer a sub-shell:

defer (
	echo foo
	echo bar
)

echo baz
