How do I run .sh files in Terminal?

I'm trying to install Craftbukkit on my Ubuntu 12.04 server. However, I'm having issues with step seven, which instructs me to run ./

If I run it as a normal user, then I get a permissions error. If I run it using sudo, then I get sudo: ./ command not found.

What am I doing wrong?

It was already executable. – SomeKittens Jun 19 '12 at 18:21

According to the wiki page of bukkit.

[...] type sh to execute the script you wrote before. Your server will start and keep running until you stop it (or until it crashes).

Thanks, this helped me find the issue (Java wasn't installed. Duh....) – SomeKittens Jun 19 '12 at 18:20
Passing an explicit shell instead of letting the system infer the right script form the shebang might lead to errors. It*s just a matter of luck that it worked here. – user unknown Jun 19 '12 at 19:10
@userunknown: Well these are the contents of #!/bin/sh screen java -Xms1024M -Xmx1024M -jar craftbukkit.jar – pl1nk Jun 19 '12 at 19:44
I told you, that it might be a matter of luck, if it works. Why don't you use sudo ./ – user unknown Jun 19 '12 at 20:55
@userunknown You have to chmod +x ./ first, in this situation.. – Eliah Kagan Jun 19 '12 at 21:05
