-
Locate the path to the interpreter for the language you are writing in with the
which
command.which node which python which bash which ruby
-
Add that path as an interpreter directive (using
#!
) on the first line of your script. For example ifwhich node
returned/usr/local/bin/node
, the first line of your script should be:#! /usr/local/bin/node
-
Write your script to do what you want.
-
Give your script execute permissions for your user with
chmod +x <path_to_your_script>
. For example if your script is calledmyScript.js
and is located in your current directory:chmod u+x myScript.js
-
Move your script to one of the directories in the path. You can discover which directories are in your path by typing
echo $PATH
into the command line, which will print a colon seperated list of each of the directories in your path. A common directory in the path for scripts you've written is/usr/local/bin/
. You will probably need to usesudo
to be able to move your file into that directory. If the script you've written has a file extension in its name, and/or some case, like camel case you'd rather modify, be sure to remove the extension and change the name of the script as you wish. Continuing with the example script calledmyScript.js
:sudo mv myScript.js /usr/local/bin/my_script
-
Use your script you're done. Tab completion will now work when you want to run your script, and
which my_script
will disclose its location. If you need to make edits just open the file in its new location and go to town.
