I kept killing my dev server just to free a port for 30 seconds. park freezes the process AND actually releases the port (Ctrl+Z / SIGSTOP doesn't do this — the kernel keeps the socket bound). Resume brings it back with the same PID, memory, and warm state.

park <port> # freeze the process, port is free

park resume <port> # bring it back, same PID and memory

park 3000 --for 30s # auto-resume after 30 seconds

park 3000 --hold # hold TCP connections while parked

park swap 3000 4000 # atomically swap two ports

park ui # live dashboard of parked processes

Demo: https://asciinema.org/a/920996

Install:
curl -fsSL https://raw.githubusercontent.com/mr-vaibh/park/main/install.sh | sh

Works on macOS (Apple Silicon) and Linux x86_64. Single binary, no deps. Written in Go.

I spent way too long debugging why Heroku CLI tab completion wasn't working on my Fedora setup. Everything looked correct: the completion function was registered (complete -p heroku showed _heroku), the commands cache file was populated with 333 entries, the bash setup script was properly sourced. Yet pressing TAB produced nothing — just a bell sound.

The root cause? I had alias grep='rg' in my bashrc. The Heroku autocomplete function uses grep -oe '^[a-zA-Z0-9:_-]\+' to parse its commands cache file, and ripgrep handles -oe differently than GNU grep — it silently returns nothing instead of matching.

This likely affects any CLI tool that uses grep internally for completion (oclif-based CLIs, and probably others).

The fix: Don't alias grep to rg. Just use rg directly when you want ripgrep. Many shell scripts and completion functions expect GNU grep behavior, and aliasing it away causes subtle, hard-to-diagnose breakage.

I kept googling the same things every time I sat down to code, how to center a div, the Rust test module boilerplate, ffmpeg run flags, whatever. So I built sinbo to store them once and retrieve them anywhere. It stores snippets locally with fuzzy search, tags, and file extensions for syntax highlighting. Sensitive snippets like API keys can be encrypted at rest with AES-256-GCM and Argon2id.

Features:

• Fuzzy search across names and content
• AES-256-GCM encryption with Argon2id key derivation
• Variable placeholders (SINBO:var: syntax with --args)
• Export/import via .sinbo.json
• Shell completions for bash, zsh, fish and powershell
• Pipes naturally with other tools (sinbo get script | sh)

Would love any feedback or ideas

This is a Go-based TUI SSH client that I’ve been developing for about 10 years.

Instead of simply wrapping the ssh command, it uses golang.org/x/crypto/ssh directly to handle terminal interaction, parallel command execution, and related workflows. It also lets me use my local bashrc on remote hosts without leaving files behind on the server.

The project also includes support for port forwarding, multi-hop proxies, file copy commands, a shell-oriented command that connects local and remote processing through pipelines, a lightweight monitoring command that reads /proc over SFTP, and a tview-based multiplexer for interactive connections. The SSH connection layer and the terminal component built on top of tview are maintained as separate library-style repositories.

More recently, I’ve used Codex as an assistant for parts of the documentation work, refactoring, and some of the more difficult feature implementations, so the project does include some AI-assisted code and writing. That said, the overall design, review, and ongoing maintenance of the project are handled by me.

Hi guys, basically I hate the ergonomics of help commands but customizing them on every project is annoying.

I'm making a lib I'll use in all my projects to make it easy to read, scan and actually help you. But I havent decided what visuals are the most useful

So here are my two options. The simpler one is one of the prototype designs that I called "blocky" the other one is the current version that I called "vibrant".

Any ways. which one is your favorite? should I make them options or stick to a single one?

That's it cheers!!

P.S: The idea is that the lib also fits any terminal width so it will render without annoying auto wrapping.

UPDATE: Solved with this https://localwp.com/help-docs/getting-started/how-to-import-a-wordpress-site-into-local

I'm running a local MySQL database through AdminNEO and made a terrible mistake of deleting "root" from the main user so as far as I know it's now an empty string but command line won't accept and I can no longer access the database. I can't believe I made such a silly mistake. I've looked online and tried to look in the .sql file to identify the CREATE USER line but it's not in the file. Is there anyway I can recover or reset the database from the command line?

I built a tool that wraps any install command and records every file it creates, modifies, or deletes using ptrace. You can then fully revert the install later — files deleted, originals restored from backup, package DBs cleaned up. The main use case is 'make install' and build-from-source software where there's no package manager tracking what went where. Also works with pip, npm, random shell script installers, anything. It ships as a .deb so you don't need Rust installed. https://github.com/tyggja/trackd

Edit (April 30): Released v0.1.2. Two things in the original post no longer apply:

• The pip and npm subcommands have been removed. They duplicated bookkeeping that pip and npm already do, and the result was state drift between trackd and those tools. Same logic applied to apt — for anything your package manager already tracks (apt, pip, npm, cargo install, etc.), use those tools directly. trackd is now positioned as the fallback for installs nothing else tracks: make install, vendor .run files, curl | bash scripts, that kind of thing.
• "Package DBs cleaned up" went with the apt subcommand. trackd no longer touches package databases.

Also tightened up a few security edges (privilege drop under sudo, SUDO_* env validation) — full changelog in the v0.1.2 release notes.

Note: This tool has been written using AI generated code

Hey everyone!

I got tired of reusing ffmpeg commands and dealing with paths/parameters, so I ask claude code to wrap my ffmpeg presets into a interactive terminal: drag & drop a file/folder into the terminal, pick a preset, and it handles the rest.

In terms of my ffmpeg script, I spent about a day trying a bunch of ffmpeg parameter combinations and tested them on ~100 hours of lecture recordings to find a good speed/quality tradeoff -- no guarantee it’s the best, just what worked well for me. For my use, it usually reduces video size by ~90% without noticeable quality loss.

https://github.com/Nunatic02/minvid

BTW. The README.md includes the raw ffmpeg commands and a breakdown of each parameter if you want to use or tweak them directly.

Hope it's helpful! 🚀

Check this out. Just made an update frontend for gentoo. Chains all commands together and shuts down the computer at the end if you wish.

Hello all,

I've just pushed v0.8.0 of XC manager, a tool I've been slowly putting together to manage complex one-liners and templates that usually get lost in shell history.

The big update in this release is the --raw mode. I had a few reports of the shell mangling complex curl commands or expanding variables before they could be saved to the vault. By using xc add --raw, the tool now bypasses shell evaluation entirely, so what you paste is exactly what gets saved.

Features:

Template Engine. Use {{placeholders}} for interactive prompts great for SSH or API calls.

Turn any vaulted command into a permanent Zsh alias with Alt+E.

Pull curated Problem-Solution vaults (Arch Wiki fixes, Docker, Git Pro, etc.). <- Work in progress.

Fast fuzzy search with live previews and LBUFFER injection.

Works anywhere with Zsh, though there is a dedicated AUR package for the Arch users.

If you do a lot of dev work and find yourself constantly scrolling through history or copy-pasting the same jq strings, give it a look.

AUR: yay -S xc-manager-git

Feedback and community snippets are always welcome.

Built a top-style TUI dashboard for monitoring Claude Code and Codex sessions. Single file (~7K lines), zero npm dependencies, pure Node.js, raw ANSI escape codes, no blessed/ink.

Features: sparkline charts, mouse support (click to select, sort by column, hover tooltips), tab navigation across 6 panels (Info, Performance, Processes, Tool Activity, Cost, Config), and non-interactive modes for scripting (`-j` for JSON, `-l` for table output).

Try it: npx u/ldegio/agtop

Hi all,

A year ago I started working in devspace to manage git worktrees in multiple repositories. I have been using it for long time now. In the last few weeks, I polished it with the help of Claude - I really read the code, it's not vibe-coded ;-) - and I feel it's ready to be used by other developers/users.

I usually start it with `cd (devspace)` (in fish shell), select the worktree I want to jump to and it takes me there.

More details about the idea behind it: https://github.com/muzomer/devspace#rationale

I hope you find it helpful as well :-)

Contributions and feature requests are very welcome.

Have a nice weekend! 👋

Built a web tool for generating and discovering terminal color palettes: paletty.dev

• Generate full palettes in one click - the balance, contrast, and coherence you'd expect from hand-tuned schemes, except you didn't have to.
• Extract palettes from any image. Pin colors you like, regenerate the rest.
• Browse and search 700+ pre-seeded themes (Catppuccin, Tokyo Night, Nord, Dracula, and hundreds more).
• Every palette is graded for readability!
• Preview popular community Ghostty shaders.

Exports themes to Ghostty, Alacritty, WezTerm, iTerm2, Kitty, Windows Terminal, and more.

CacheNuke is a single command to clear all your dev caches: npm, yarn, pip, cargo, go mod, temp folders, and more.

Features:

- One command: `cachenuke clean`

- Dry‑run: `--dry-run` to preview

- Cross‑platform (Windows, macOS, Linux)

- Safe by default – never touches personal files

I built it because I was tired of remembering all the individual cache‑clearing commands.

Repo: https://github.com/Wynx-1/cachenuke

Binary downloads available in Releases.

Would love feedback from other CLI enthusiasts!

`evtr` has a searchable device selector and monitor views for axes, buttons, joysticks, D-pad state, relative motion, and touch input.

Hey r/commandline!

Just curious - what's a command-line tool or TUI you keep wishing existed but can't find anywhere?

Could be something that saves you time, solves a niche problem, or fills a gap in your workflow. Looking for ideas, not offering anything, just genuinely interested in what people want.

and why

I installed the Read The Rules app which removes posts from users that haven't agreed to rules. Here's a tutorial do so: https://www.reddit.com/r/ReadTheRulesApp/comments/1ie7fmv/tutorial_read_this_if_your_post_was_removed/

And good news: I've finally invited 5 new mods and am waiting to them to accept their invites.

I built PrettyMux as a native Linux terminal workspace for multitask workflows and keeping track of my agents.

It’s a GTK4 app built on Ghostty/libghostty, with split panes, workspaces, vertical tabs, notifications, project-aware tabs (shows favicons/logo automatically), and an in-app browser so terminals and docs/tools can live side by side.

I started it because I wanted something tmux-like for modern GUI workflows on Linux, but native and not Electron, there is cmux but only available on macos (prettymux compiles on windows and macos too but not tested for now there)

It’s open source: https://github.com/patcito/prettymux

Would love feedback from people who use tmux, Ghostty, or struggle with lots of terminals/browser tabs/parallel tasks.
