 - Force the removal of a pool with `./pool.sh remove-force <poolname>` all running processes will be killed and the pool will be deleted
 - Additional properties can be attach to processes with `./pool.sh setp <poolname> <procid> <propname> <propvalue>` Defaults properties are `<cmd>`,`<procpid>`,`<startat>`.
 - Properties can be retrieve with `./pool.sh getp <poolname> <procid> <propname>`
-- Finally, all the processes output file can be retrieve with `./pool.sh ls <poolname>`
+- Available pools can be retrieve with `./pool.sh ls`
+- All the processes output file can be retrieve with `./pool.sh ls-output <poolname>`
 
 **Finale quote:** No checks are performed on the pool.sh arguments. Be sure to use the right ones. Defaults configuration requires access to the `/tmp` directory.
