which and find not working to locate ruby.exe path

Question

From the home directory
which ruby.exe & find ruby.exe return "no such file or directory" However, I'm able to execute .rb programs in rubymine.

Answer 1

Try this instead:

which ruby 

If you would also like to be told when certain commands are shell builtins, you can use this:

type ruby

In Unix like operating systems the filename suffixes which traditionally denote executable files on DOS and Windows such as .exe, .com, and .bat do not apply! Instead, file permissions bits are used to denote which files are executable.
