If your target is *understanding* linux, then I'd disagree with the
first paragraph.

Learning computer languages is like learning foreign ones: aged 15 I
could read Xenophon in Greek but writing sentences was a struggle.
To understand linux, you'll need to understand C, shells, several
scripting languages, and specialist tools (coccigrep's a new one to
me), but you don't have to be able to write in them.

OTOH to do sysadmin you need to be able to write basic shell programs
and in a scripting language. I say *basic* shell: if it requires bash
arrays or more than two lines of , say, awk, then I switch the whole
thing into python.

Jolly good idea.

Cheers,
David.
