Why Command Line?

1. If documentation is "recorded steps for a human to execute",
   then command line is "recorded steps for a computer to execute".

2. Good balance between:

   • Steps that a human can read and write relatively quickly.
   • Steps that a computer can understand.

3. The script is software, so once it is written, it can be re-run by re-entering the commands.

   Tends to be faster than guiding a person through a graphical user interface.

4. Different steps of a process can be chained together relatively quickly.

   step_1 |
   step_2 |
   step_3
   
   echo qqwwww  |
   tr 'qw' 'ha' |
   rev
   

5. This is a transferable skill – this can be used:

   • in different products
   • in different teams
   • in different workplaces
