The terminal is there to do your bidding.
It does exactly what you tell it,
you just need to find out how to tell it exactly
what you want it to do.
That's just a great adventure of learning.
Most commands are pithy abbreviations:
mv move
cp copy
ls list(files)
cd change directory
rm remove
with some historical artifacts embedded in.
tar tape archive
grep global regular expression print
(which you can read some historical context to understand)
where a file (or stream) is usually the thing being operated on.
Be brave.
It would be sad if you came all this way to freedom,
and gave up before you realized your real power.
Free yourself then free others.
