From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I'm a big fan of jq. It's a domain-specific language for manipulating JSON data.
ImageMagick is like ffmpeg but for images.
inotify-tools has command-line utilities that can be used in a Bash script or a Bash one-liner to make arbitrary things "happen" when something "happens" to a file or directory. (Then the file is opened or written to or renamed or whatever.)
I probably should mention rsync. It's like a swiss army knife for copying files from one place to another. And it supports "keeping files syncronized" between two locations.
Of course, there's tons of stuff that you pretty much can't talk about Bash scripting without mentioning. Sed, awk, grep, find, etc.
Also, I totally relate about the terminal giving more dopamine. I kinda just hate going on a point-and-click adventure to do things like image editing or whatever. To the point that I've written a whole-ass domain-specific-language to do what I want rather than use Gimp. (And I'm working on another whole-ass domain-specific-language to do a traditionally-GUI-app sort of task.)
jq
is indispensable.A bunch of GNU tools have added JSON output and it's so good. Like, GNU
column
can take tabular data and convert it into JSON really easily. It's like the perfect text stream.OMG how did I not know this... It just might be time to switch to nushell/elvish.
