The thread at https://github.com/theZiz/aha/issues/20 suggested a case-insensitive regex through sed but the exact suggestion failed for a few reasons I will explain below.
First the bash alias (requires both aha and perl):

The goal of this book is to document known and unknown methods of doing various tasks using only built-in bash features. Using the snippets from this bible can help remove unneeded dependencies from scripts and in most cases make them faster. I came across these tips and discovered a few while developing neofetch, pxltrm and other smaller projects.
The snippets below are linted using shellcheck and tests have been written where applicable. Want to contribute? Read the CONTRIBUTING.md. It outlines how the unit tests work and what is required when adding snippets to the bible.
See something incorrectly described, buggy or outright wrong? Open an issue or send a pull request. If the bible is missing something, open an issue and a solution will be found.
Sort of tanslated from the first “via” (note that “mit Alles und Scharf” is hard to translate; it’s somewhere between “everything but the kitchen sink, but done right” and “right on the money”):
Bash Prompt Overkill: https://github.com/nojhan/liquidprompt is a Bash “Prompt doing it all right”-extension, which doesn’t care how much any feature costs as we have cores, gigabytes and SSD.
Liquid Prompt automagically recognises context and enables a plethora of features in the prompt when needed based on that context.
It’s like pixie dust for your prompt.
You can configure everything, but you don’t have to: the out of the box experience is already like pixie dust for your prompt.
It works on OS X too and is part of homebrew:
$ brew install liquidprompt
==> Using the sandbox
==> Downloading https://github.com/nojhan/liquidprompt/archive/v_1.11.tar.gz
==> Downloading from https://codeload.github.com/nojhan/liquidprompt/tar.gz/v_1.11
######################################################################## 100.0%
==> Caveats
Add the following lines to your bash or zsh config (e.g. ~/.bash_profile):
if [ -f /usr/local/share/liquidprompt ]; then
. /usr/local/share/liquidprompt
fi
If you'd like to reconfigure options, you may do so in ~/.liquidpromptrc.
A sample file you may copy and modify has been installed to
/usr/local/share/liquidpromptrc-dist
Don't modify the PROMPT_COMMAND variable elsewhere in your shell config;
that will break things.

Reason? Want to show the output of this as the last boot sequence line:
hostname ip route
echo
ip address | grep -w 'UP\|flags\|inet\|inet6'
echo more detailed info through "ip address" and "ip route"
cat /etc/resolv.conf | grep nameserver
Hosting Grumpydev Imageflair locally ended with two issues left: an empty image and my wish to include more complete StackExchange bits like the current StackExchange flair does.
I thought fixing the empty image would take a rainy day. It actually took a few rainy hours.
The drawback of having fetchmsttfonts is that the original Microsoft versions of these fonts are downloaded from corefonts.sourceforge.net each time the fetchmsttfonts package is updated, potentially overwriting newer versions of the fonts in that directory. If you don’t want that, use the trick at (not yet archived at the WayBack machine) font handling – install fetchmsttfonts, copy fonts, rpm -e fethmsttfonts, copy fonts back.
Having the fonts installed, I thought the only thing I needed to fix were the multiple references in config.php from that pointed to Arial.TTF. I took the poor man’s approach and just did this being in the directory of config.php:
cp /usr/share/fonts/truetype/arial.ttf Arial.TTF
Filled Imageflair
That didn’t work either: still no text showed.
So I decided to run imageFlair.php from the command line after setting $imageflair_debug = true; in config.php which then resulted in all sorts of warnings like
PHP Warning: imagettftext(): Could not find/open font
After reading I decided to build a small php-gd.tester.php script containing phpinfo(); and gd_info showing these portions for PHP GD (non-relevant bits stripped):

A friend of mine made the mistake to capture some CDs using WMA files and throwing away the CDs. His old Nokia could play them, but not his new iOS and Android devices.
One of the things after moving most of my things from copy.com to Google Drive was the direct (public) download URLs that copy.com provides. DropBox has them as well, but Google Drive lacks them in the UI.
There is a URL format that does allow for direct download though:
While Google aims for Drive to be a competent Dropbox competitor, there’s one small but key feature that isn’t easy: sharing direct download links. Fortunately, you can create your own.
Since I’m a command-line person, I’ve opted for a sed conversion that wasn’t in the above list. I choose sed because it allows you to convert either a line or a complete file at one time.
There are a few indispensable resources to get my regex expressions right:
Where bash aliases have no parameters (i.e. the arguments are put after the end of the expansion), functions have parameters. So if you want to pass all function parameters to a command inside a function, you have to use “$@” to pass all parameters.
This fragment fixes https://drive.google.com/open?id=FILE_ID printing each fix on one line using the p for printing command in sed:
sed -n 's@https://drive.google.com/open?id=@https://drive.google.com/uc?export=download\&id=@p' "$@"
The second fragment fixes https://drive.google.com/file/d/FILE_ID/edit?usp=sharing and https://drive.google.com/file/d/FILE_ID/view again printing each fix:
sed -n 's@https://drive.google.com/file/d/\([^.]*\)/.*@https://drive.google.com/uc?export=download\&id=\1@p' "$@"
Some more remarks:
The FILE_ID is obtained from a capturing group during the match using \([^.]*\) and using the value in the replace with \1 as reference.
There is backslash escaping of the parentheses because that’s the sed way.
I’ve used a non-greedy \(.*?\) capturing group (sed can’t do that) but \([^.]*\)/ which matches any non-slash inside the capturing group until the first slash outside that group.
The final part is combing both replacement into one sed command:
sed 's@https://drive.google.com/open?id=@https://drive.google.com/uc?export=download\&id=@;s@https://drive.google.com/file/d/\([^.]*\)/.*@https://drive.google.com/uc?export=download\&id=\1@' "$@"
Final remarks:
I removed both the –n (not printing anything) and the p (print only matches) which means everything is printed: non matching lines without replacement and matching lines with replacement.
