jplitza / zbell.zsh

Last active February 4, 2017 20:47 — forked from oknowton/zbell.zsh

	#!/usr/bin/env zsh

	# This script prints a bell character when a command finishes
	# if it has been running for longer than $zbell_duration seconds.
	# If there are programs that you know run long that you don't
	# want to bell after, then add them to $zbell_ignore.
	#
	# This script uses only zsh builtins so its fast, there's no needless
	# forking, and its only dependency is zsh and its standard modules

Created January 7, 2015 14:36
