How to turn your scripts into commands in Linux and Mac command lines / terminals

First create a bin folder in under your user.

To see where we are we use pwd and to see where is our user folder we can use echo $HOME

and then switch to your userfolder (if you just opened the console you should be there already). The command cd with no parameters bring you to the home folder, otherwise you can use cd $HOME

The folder does not have to be named “bin”, it can be named whatever you want. I name my folders for scripts “bin” as the systems usually use a folder named “bin” for executables.

This articles talks about the creation of thumbnails on the fly, somebody requests it, it is then created, served, and removed.
