Making a Ruby Script Executable

Comment

#Suppose we have the file greeter.rb. To make the file executable, we run 

ruby greeter.rb

# One can also make the above file executable by just typing 'greeter' but
#one has to put the below command at the top of the file

	#!/usr/bin/env ruby
    
#Second, we need to make our script executable, which requires changing the file permissions.
#Bascially, files have three types of permissions. They can be read, written, and executed.
#To check permision of a file,On the command line, navigate to the directory holding the greeter.rb

	ls -l greeter.rb

#To add execute permissions, run the following command
	
	chmod 755 greeter.rb
	mkdir -p /usr/local/bin/
