On the topic of things you didn't know the shell did: I found out about sequences recently and love them:

$ echo {0..19}

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

$ echo {00..19}

00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19

Looks like it also works with single letters.

$echo {A..D}

A B C D

Hmm, I'd always used the "seq" command for that...

$ echo `seq 0 19`

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

Perl is very much like this too.

$ perl -le 'print join(" ", "00".."20")' 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20

wow, genius!

(the second doesn't work on older versions of bash, like macos)
