Usage

This is a general state manager for Bash scripts. To use it, you must define the following in a separate script and then source the statemgr file:

name_

A string variable with the name of your manager.

function save_state_()

A function that saves the current state/profile to a file. The function will receive the output path as its first and only argument.

function load_state_()

A function that loads a given state/profile from a file. The function will receive the same path used to create the file as its first and only argument.

Example

The following will manage desktop background images set with feh.

#!/bin/bash

name_=feh

function save_state_()
{
  cp ~/.fehbg "$1"
}

function load_state_()
{
  sh "$1"
}
