Terminals and You

Neill R.

Why Terminals?

Single Responsibility Principle

  • Do one thing
  • Do it well
$ ls
Documents Downloads Pictures Videos

Look like a hacker

History

  • Thompson Shell (1971)
    • Data redirection
    • Interaction-only
  • Bourne Shell (sh) (1977)
    • Scripts
    • Variables
    • if/for/case
  • Bourne Again Shell (bash) (1989)
    • Free!
    • Tab completion

But what do I do?

Basic Commands

  • ls
  • cd
  • mkdir/rmdir
  • cp
  • rm
  • mv
  • more/less
  • man

Redirection

  • >, >>
  • <, <<, <<<
  • |

The Last Ingredient:

Creativity

(Insanity)

tr -cs A-Za-z '\n' |
tr A-Z a-z |
sort |
uniq -c |
sort -n |
tail

Not too shabby.

Shortcuts

Efficiency is worth it
