There are times you run a command in cronjob in a specific interval. Let's say you run that command every hour.

If your command copies a huge file, or you are doing a heavy task that may take longer than 1 hour sometimes, then you need run-one
command in your arsenal.

run-one: run just one instance at a time of some command and unique set of arguments (useful for cronjobs, eg)


Sample run-one command:

run-one rsync -azP $HOME $USER@example.com:/srv/backup
