Very interesting, the name basically gives the game away.
You give the tool a list of git(hub) repositories and a command (or more advanced script files) and it runs it against them.

You could for example create a file in each one. Or change some variable. Or grep and sed something from one thing to another thing. Or or or.

Honestly not seeing myself using it that often - but the fact it exists is fascinating to me, and the naming is just genius. Though I am a little sad that it seems to only work for Github projects.

Same thing as GRON - turn JSON into stream-friendly (i.e. greppable) destructured text.
Just faster! I suppose. Haven't really tried it myself

GReppablejsON!

Super awesome for de-structuring json responses to then simply work with through grep or other text-only speaking stream tools on the command line.

A JSON Query Language CLI tool. A little like the venerable jq a little not, has different selection (or 'query') syntax.

Basically you pass in JSON to select specific JSON from whatever data.
Feels a little weird to me at first, but might actually be easier for intermediate/advanced use cases then the mind-bending mess jq sometimes turns into for me

(or rather, the constant trial and error with jiq that it turns into)

abduco provides session management i.e. it allows programs to be run independently from its controlling terminal. That is programs can be detached - run in the background - and then later reattached. Together with dvtm it provides a simpler and cleaner alternative to tmux or screen.
(dvtm being a terminal window manager to have multiple tabs or buffers)

However, on its own it can also bring session management to something like wezterm which has amazing window management on its own but no real session management. Very neat and 'unix-y'

Efficient Duplicate File Finder with extensive cli interface

File duplicate finder with a simple GUI. Has a cli frontend as well.

Cute little terminal TUI browser for gopher, gemini, finger (and your local files).

Runs on basically everything and uses some vim-like keys. Can also be made to work the the web but.. do you really want to?

A tool doing basically the same job of gnu parallels but with really nice cli interface - simple quoting, reading inputs from file, providing timeouts, retries, multi-line commands, continue flag. Really nice!

a simple named pipe management utility.

Really nice utility which creates ad-hoc named pipes for you which you can then use later. The Readme explains it well.
Can honestly have so many uses, it's staggering but I think it is one of those programs you forget about until you really really need it.

Sync worklogs between multiple time trackers, invoicing, and bookkeeping software.

Can synchronize for example timewarrior, toggl and clockify which seems pretty nice! Not used it myself since I completely moved to timewarrior.

Wonderfully useful program to show output of terminal commands in screenshots. Not super customizable but the default output looks good enough.

Can be useful for showing people how to accomplish something, blog entries, and especially for READMEs of command line programs.

TSV data wrangling utilities from the command line.
Written in D language.

Watch YouTube from the comfort of your terminal. (Well, technically opens an mpv/mplayer instance to display the actual video).

Can also do only audio so you stream audio through your terminal in the background.

Works without any api keys and can search individual content, playlists, create local playlists, downloads videos and more.
Really nice piece of software!

A fantastic e-book reader for the terminal.

Supports common ebook formats like epub, mobi, awzs.

Can currently not show images in-line (would be a nice project for e.g. kitty image protocol), but can open them in your external image software.

Commandline ChatGPT interaction program, using golang. Has few quality of life features (but a pre-determined role to generate and execute shell commands [DANGER DANGER] or to generate code for you).
Has basic interactive mode.

Does NOT require OpenAI API keys, uses API from a different server. (For now, no key required).

Commandline ChatGPT interaction program, using python. Has a few quality of life features like conversation continuing, and token cost estimation.

Requires OpenAI API key to function.

Has quite a few quality of life features like pre-determined roles (in yaml format), conversation saving, repl mode and more.

A shell script to interact with ChatGTP or DALL-E through CLI. Requires openai api key.
Built solely with (bash) shellscript, so no other interpreters required (python, node, ..)
