Practice to build your Command-Line Utility

Specify which languge to excute your script by adding first line as follows

   #!/usr/bin/env ruby

Put your script in usr/local/bin and make sure it is executable(chmod +x my_script)(This is already set in the path, you can check by doing an echo $PATH)

Create a folder in your home directory called bin. (For your personal scripts)

• cd ~ (Takes you to your home directory)
• mkdir bin (create a bin folder)
• vim .bash_profile (to set path environment variable)
• export PATH="$HOME/bin:$PATH" (Press i then add this line and then do esc and type :wq)

Now you can just type the name of your script and run it from anywhere you want.
