This was some quick research on something that I found interesting. Was trying to solve a problem, but this might be overkill. It is intersting though!

Mermaid - Mermaid is a Diagramming tool for everyone.
It does flowcharts, class diagrams, sequence, state, entity, gantt, and others that seem to be pretty useful.
It seems that there are some VSCode plugins that support this. Markdown Preview Mermain Support is one such. There are others for creating PDF files …
It takes git status lines and converts it to a string with no line feeds, and then adds it to the clipboard for easy copying.
This has been a issue with using git when you don't want to have to do a git add . command. Grid …
Various ways to create a PDF from Markdown
The following sections assume that you want to use a script (or within a script) to do the conversion. There are probably other tools out there that can be used at the command-line for doing that as well.
So, if you need …
How to "print" to a string in rich
On an issue that I submitted to the repo, asking if there was a similar interface in rich as what textwrap gives (specifically, the subsequent_indent value), I was told about tables and table.grids, which worked, but I still would like to …

locate is a good alternative to using find
As noted in the finding the Tools/scripts subdirectory in stackoverflow:
This command
$ locate "Tools/scripts/diff.py"

How to get directory listing with human readable file sizes
Usually, it doesn't matter too much, but it's nice to have the sizes shown rather than the bytes.
alias lh='ll -h'
Now, should have two decent directory listings: ll and lh.
There are times, where I want to see what my setting is and others, I need to be able to set to what I want, after it's been reset for me.
I've noticed that for whatever reason, there are times where getting git from grid, resets my …
Pretty useful to have and know and I always find something, use it, and then forget where I used it (and how) but only remember that I did it. Sigh.
Here are several useful links:
How do I make python programs behave like proper unix tools? - I like ixtmixllix's approach …
It has some good stuff. I ran across it as I was looking at viewjrnl, a different viewer for jrnl (it doesn't work like it should, or I'd be writing about it instead). Anyway, the main tool it used was jq.
jq is like sed for JSON data …
Seems interesting and could be useful, as it can map/change keys for my keyboard, and it's open source, which is nice -- Karabiner-Elements. I'll give it a try.
And, it has a Karabiner-MultitouchExtension tool that looks really interesting!

Here is an article that explains some about both Pipenv and Poetry Package Managers. Good reading and some pluses and minuses. This article does give some advice …
I don't always need this, but at times, it is quite useful - view files in zip.
One command I was unaware of and one I had forgotten: zipinfo Archive.zip and unzip -l Archive.zip. Both should do the trick.
An interesting way to look at and fix a problem. Bash - when did I run that command?
I might try to use something like that for a different problem, but the solution might be just as valid.
Found a cool way to do a script (by Sparhawk in StackExchange) so that if you use sudo more than once or if a command requires you to enter your password, you should only have to enter it once.

}
alias nicepath=nice_path
I made it an alias as well …
In the Include Files in Bash article, it gives some good examples (i.e. one reason to do this is for data, so it doesn't clutter up your script -- not stated, but I would use it this way).
Basically, it amounts to the following:
