Hey DT, thanks for this great, inspiring video. I came across -chem- - a groff preprocessor for producing chemical structure diagrams. Most ppl might not be very interested but as a high school teacher in chemistry and physics I will have a closer look. The syntax of the chemfig-latex-package is quite idiosyncratic (not to say annoying...), so perhaps there is a easier way to do it this minimalistic way. Again: great idea! Let me add an interesting way of handling keyboard answers to shell-scripts. In my book on shell-scripting by the German authors Kania and Wolf they present a great way to press a single key WITHOUT pressing return afterwards.
They put terminal in a raw mode first and then using dd!! Like this:
char = ' '
stty raw -echo
while [ -$char- !=-q- ]
do
char =$(dd bs =1 count =1 2>/dev/null)
done
stty -raw echo
Interesting way of 1.) setting tty to a raw mode and 2.) copying stdin to sdr(err)out with dd.
Nice weeekend everybody!

absolutely great video ... serves its purpose well but at the same time it is not a video which just tells you steps without explaining why those steps ... and in the process teaches smattering of scripting ... absolutely great ... if ever there is hall of fame for linux instructional videos this should be in that ... and already high quality comments are here which is a bonus ... thanks for video and comment writers

Hey there I am a big fan. I was just wondering what is your tool of choice for making notes. I am finding writing notes more and more important in my day to day work. I have seen mention of inkdrop app and Joplin. Is there any you would recommend. I don't mind paying if it's a good service

Thank you Derek, that was a very cool vid, I tried to solve the problems
along the way by pausing the vid and finding solutions by myself, that
was very educational :)
For the random:
man -k . - awk '-print $1-' - shuf -n 1
work too :)

Curious, im getting this with termite
(termite:263210): GLib-WARNING --: 11:05:53.078: GChildWatchSource: Exit status of a child process was requested but ECHILD was received by waitpid(). See the documentation of g_child_watch_source_new() for possible causes

Thank you, Derek. Although I don't remember much about their details now I read man pages for the first two years or so that I began with Linux. And everytime I use a new program I at least scan the man page.

I have raspbian lite on a pi-zero-w and I wondered how to get X window capability for stuff like dmenu? I don't want to install the full desktop as that kind of defeats the object hereof learning Linux

Just use bash command substitution together with sed's substitution with grouping: man $(find /usr/share/man/man1 -type f -shuf -n 1-sed 's+.-/\(.-\)\.1[-.]-\.gz$+\1+')

When you use sed with .gz, the . is a special character that means anything, which could mess up with stuff like libgzip (if that exists), which would become liip.

That's very nice. Yet again, I can't use it via putty (error -cannot open display-) . Cannot switch to full-on linux. But I could not live without a close Linux box.
