How to used exit codes in code
An exit code is generated when you specify a logfile message e.g fn_script_log_fatal. When you want the script to exit you must use core_exit.sh rather than just the exit command. core_exit.sh will then handle the exit and specify the last know exit code. So if the more recent command was fn_script_log_fatalthen the exit code will be 1
Examples
fn_script_log_fatal "RCON password is not set"
core_exit.sh
This will exit with code 1
fn_script_log_error "RCON password is not set"
core_exit.sh
This will exit with code 2
fn_script_log_error "SteamCMD is missing"
LinuxGSM installs SteamCMD
fn_script_log_pass "SteamCMD has been installed"
core_exit.sh
This will exit with code 0
