SSDcronTRIM is an intelligent cronjob which, depending on the usage of your Solid State Disk(s), automatically decides how often the SSD(s) should be trimmed. The more data you have on your SSD(s) the more often they will be trimmed.

It is intended as a fire and forget app which, once installed, does everything fully automated. In fact it is so clever, you should be able to install it on any linux system without using the package manager of your distribution. Just open this script with your favorite text editor, add the partition(s) which should be trimmed (as a space separated list into the variable SSD_MOUNT_POINTS) and then execute SSDcronTRIM without any option.

Beside the needed cron job(s) it also creates a man page on the fly. Both, the cron job(s) and manual page installation does not interfere with your existing distribution. And if you want to get rid of this script just start it with the deinstall option and it will remove any cron job(s) and the man page.
