Linux: need to run gmod on wine but cant find exe for it

So, i just got a OS called Jolicloud (google it), and it runs on Linux. What is the .exe that gmod uses because i need to put it in wine to start gmod.

Garry’s Mod uses hl2.exe

Steamapps\USER\garrysmod\hl2.exe

Bear in mind that hl2.exe won’t run without Steam.

you have to start it trough Steam
