Chapter 17 to 19
Jim: Here's what I use regularly ; I have wgerecur as an alias for this :
wget --page-requisites --convert-links --recursive --no-parent

Played with locate, and some of finds options; xargs - interesting...
18
Played with gzip/gunzip/zless/zcat and bzip2/bunzip2; used tar with various options - some of the books examples have lots of options and piping, some of which I'd like more practice with/ be able to understand better. Used some ssh and tar for tricky file transportation from csmarlboro.org. Also zip/unzip (only good for interfacing with 'Legacy' systems).
Backed up my source code to csmarlboro.org with rsync.

grep and regex's - '^weee[ee!][^p]..$'
Very useful for crossward puzzles, as the book points out: grep -i '^[a-c].t.[rs]$' /usr/share/dict/words
