#!/bin/bash | |

# Watch current directory (recursively) for file changes, and execute | |
# a command when a file or directory is created, modified or deleted. | |
# | |
# Written by: Senko Rasic <senko.rasic@dobarkod.hr> | |
# | |
# Requires Linux, bash and inotifywait (from inotify-tools package). | |
# | |
# To avoid executing the command multiple times when a sequence of | |
# events happen, the script waits one second after the change - if | |
# more changes happen, the timeout is extended by a second again. | |
# | |
# Installation: | |
# chmod a+rx onchange.sh | |
# sudo cp onchange.sh /usr/local/bin | |
# | |
# Example use - rsync local changes to the remote server: | |
# | |
# onchange.sh rsync -avt . host:/remote/dir | |
# | |
# Released to Public Domain. Use it as you like. | |
