Error message after installing Sublime Text 3

Question

I found on a website that I can install sublime 3 on Fedora 20 using the following command: curl -L http://git.io/3Wr2CQ | sh After running the command I can't open Sublime. I get the following error: /usr/local/bin/subl: line 2: [: ==: unary operator expected

Please see below a copy from the terminal:

Change ${1} into "${1}" so it evaluates to an empty string in shell when no parameter is given.

Also check the location of sublime_text. I had to change path from /usr/local/sublime-text-3/sublime_text to /usr/local/sublime-text-3/sublime_text_3/sublime_text.
