where is the path of Ruby executable file and the gem.bat in linux?

Question

I need to set a path Variable on PHPStorm for the ruby executable file and the gem.bat.

I am using a virtual machine that has installed CentOS, and I just ran

$ sudo yum install ruby

Now I need to find the path, but I have no idea where ruby was installed under which directory

Answer 1

Use which or type command:

$ which ruby

or

$ type ruby

It will show you the path of the executable if the directory contains the executable is listed in PATH.
