15. CRC FLOSS DAB tools usage
● "In the beginning... was the command line"
○ CLI (man, help, advantages)
○ Pipes
○ Basic scripting
● CRC-OpenMokast
● CRC-DabMod
● CRC-Dwap
● CRC-DabMux

16. In the beginning, was the command line
$ make love
make: *** No rule to make love. Stop.
$ whatis sex
sex: nothing appropriate
$ %blow
%blow: no such job
$ man woman
No manual entry for woman

17. Pipes are fun!

18. Script essential
#!/bin/bash
{your commands here}
{multi-line
command}
{command to run in background &}

19. Script permissions
$ chmod u+x {script name}
