This is something I've been thinking of for a looong long time: Creating a course covering my favourite linux commandline productivity techniques!
The background is that during my year at UPPMAX super computing center, where we were workikng all days in the terminal, I started looking for the perfect set of easy to implement techniques, that could save me the most time and unneccessary strains in the wrists etc, without getting me drowned in complicated setups that would not work on all computers etc. So, I started thinking about gathering all these lessons in a course.
Not until this summer, when I discovered the awesome udemy platform, did I get it done though (and many months later, after I got the last bits finished, it got published)!
Guess if I was happy about the very first review I got, was a full five star! :), reading "Excellent course. I especially like the coverage of 'screen' and 'terminator'. Ben"):
Anyways, find below a special 50% off coupon just for you my blog readers (with life-time access to the course). Hope you will enjoy the course as well:

Hope you will enjoy the course as much as I enjoyed creating it! :)
Somebody told me they always use US keyboard for coding, and that it really makes a difference. I typically don't care too much about such, but when I started getting a slight pain in my wrists the other day, after many days of intense bash-/vim-/screening, I decided to make a try ... and my hands and wrists are forever grateful!
Finally it starts to make sense why somebody would choose a weird character such as " for switching between windows in screen! (something you do very repeateadly sometimes), but having it just one step to the right of the natural position of your right pinkie, makes more sense than the awful crippled left-hand grip to get [shift]- on the swedish keyboard.
Coders in general will save some sanity by avoid the crippled right hand-grip with AltGr+[numkey] to get to
The rest is maybe a little more specific to heavy bash/vim/screen usage. I'll outline a few that I noticed below:
:, for the ubiquitous
:win vim (for saving( is very comfy placed under your right pinkie (with shift).
$sign is much comfier (for selecting to end of line in vim), avoiding another crippled AltGr-grip.
/, for searching in vim, is really nicely placed one step down and right from the right pinkie.
"is nicely placed just one step to the right of the pinkie-placement.
~, even though requiring a slightly crippled left-hand grip even in US, at least prints out directly, as opposed to the required space to force it to print, in SE.
I'm sure there are many more, but these should be enough to make it worth to try it out a little if you're spending a lot of time in bash/vim/screen. In short: Only now I can see how anyone can really love working with these vim commands!
Only thing remaining is to find a nice place to map the åäö:s.
So far, I have added these two aliases to my
~/.bash_aliases, though, for quick switching between Swedish and US:
alias kbse='setxkbmap se' alias kbus='setxkbmap us'
[samuel ~]$ cat ~/.inputrc
set editing-mode emacs
For formatting a 3-digit integer (that is, 2 leading zeros for 1-9):
printf %03d $i
... where $i is the number in question.
sed -n '[1st line no],[last line no]p' [infile] > [outfile]
