Original GitHub issue: https://github.com/GameServerManagers/LinuxGSM/issues/296

We're using your script (great job), and it was logging things fine on Debian. For whatever reason, the L4D2 servers weren't stable there so we migrated to Ubuntu 14.x. Ever since that, the console logs are empty. We're not sure what we did that could cause that, but no matter what logging variables we change and adding / removing -debug from the command line, the files are always created but always 0 bytes. tmux is installed also. Do you have any insight?

SOLVED
Upgraded tmux to 1.9a and the log files contain data again.

ISSUE:
/home/l4d2-1/functions/fn_start: line 72: fn_check_logs: command not found

Do we need to care about this?

I manually downloaded fn_check_logs and added it to the functions directory, however, this error message persists:

If you get any bugs like that always delete the functions dir. This will make sure you have the latest version :-).

Nope not yet. Haven't been at my laptop today. Will take 2 mins when I get a chance :-). The bug doesn't break anything though so no need to worry.

I did it manually in our copies. I'm new to GitHub and don't know how to contribute, else I'd do it here for all.

fn_check_logs(){
functionfile="${FUNCNAME}"
fn_runfunction
}

Go to whatever file you want to edit in the main list and there's an edit button to automatically clone the repo and once you're done editing your copy you can send us a merge request
