Unable to run a file on disk

So lately I have been working on a website and I got most of my website done but now I'm adding commands that a admin can use while on website it's like a command prompt on a website or console anyways I have this one command : website/beta what this suppose to do is run the latest beta version of the website but the problem is when I type the command it says no file found, so what my problem is im trying to get a file to run on the clients computer that is on the server and when i do it says no file found.. and im guessing i need some sort of pkt sending system from the server to the client to run the file i want to work.. which i believe would be something like this inzernet.GET(ip,file) but when i try to run the program it says a nil value.. so i just need a boost so that i can send the file from the server to the client. any ideas?

Two options; either copy the file from the server to the client, or have the client tell the server to run the file.

I'm afraid I can't comment on the best option without a whole lot more context. I'm assuming the latter option is best, as it sounds like you're going for something along the lines of Telnet/SSH?

I believe ssh but I've found out that it's nothing to do with me it's the internet that needs have that setup but if I was going to have the client run a file from the server there would have to be a variable in the index to run the file I believe
