When using the Forge interface, you can always view the Latest Deployment Log. What I'm trying to reach, is the complete list of past deployment logs. Is that possible? The log files' location also works as I have SSH access to the actual server.
Found the answer in Laracasts Forum
The logs reside in ~/.forge directory. You have to look for ~/.forge/provision-* files. For each provision you'll find a .sh and a .output file. As the names suggest, first one includes the commands that were run and the second one includes the output of all those commands.
