The Linux script command has been around for ages and provides a simple but useful service. It lets you record command line activity – both input and output.

The script command will run your .bashrc start-up file when you start your command recording. It will save the commands you enter along with the output generated by them.

You could even embed an executable file in a script — even another script — and then execute that script which might unpack another script. It boggles the mind.
