| # This script is used to control Transmission jobs based on available disk space. | |
| # | |
| # This should be run as a cronjob (every minute) on the server/computer running Transmission | |
| # | |
| # If you use a download manager tell it to add jobs as PAUSED | |
| # | |
| # - If disk is nearly full (limit) then stop all jobs | |
| # | |
| # - Gets list of running jobs | |
| # --- Checks if there is enough space to complete all runnning jobs | |
| # --- Stops one or more jobs if there is not enough space to complete | |
| # - Gets list of stopped jobs | |
| # --- Check size of job and starts it if there is enough space to complete the job | |
