Hallo hyde!

 hd> Thank you for that suggestion. I have seen that site in passing.

It can be overwhelming at first but as always practice makes perfect.  Also
just reading the individual packages in "Chapter 6" can be an excellent source
of what is provided by each package which will assist in further investigation
and knowledge.  For example,
http://www.linuxfromscratch.org/lfs/view/development/chapter06/coreutils.html,
lists under "6.54.2. Contents of Coreutils" the installed programs as well as a
short descrption which can be very revealing.  I use many of these programs in
the bash script that actually is creating this reply.

 hd> I found a number of free FOSS ebooks and they have tons of information.

Excellent.

 hd> I discovered TMUX last night and am really enjoying it.

I have it here as well.  It is definetly something worthwhile keeping close and
if it helps to further learning of commandline and/or shell scripting then
bonus.  :-)

Het leven is goed,
Maurice
