Where is the Git-Lab executable on the server?

The system that I work on is essentially a content management system that allows user configurable URLs to access webpages generated from user entered content.

This is a bit of a clash with the configurable GitLab access URL, since anything I set up for GitLab access in its config file would be interpreted by the system as one of its user configurable URLs.

Because of this, I will have to code in an exception for a GitLab access URL, but I will need to know where to direct the code to run GitLab… Where is the GitLab executable installed on the server? (I already did the install.)
