try
Inspect a command's effects before modifying your live system
Try is a Linux command-line utility that lets users run a command and inspect its effects before deciding whether to commit those changes to the live system. It works by using Linux namespaces through unshare together with overlay-based filesystem techniques so that commands can execute in an isolated view of the system rather than directly modifying the host environment immediately. This makes it useful for experimenting with package installation, system changes, and other shell commands where users want a chance to review the outcome first. The project is careful not to position itself as a full security sandbox, since trusted commands can still make network calls and the tool is presented as a prototype rather than a complete isolation boundary. It supports multiple Linux distributions and can fall back to mergerfs or unionfs in environments where overlayfs on nested mounts does not work as expected. In practice, -

zsh-autosuggestions
Fish-like autosuggestions for zsh
zsh-autosuggestions is a popular Zsh plugin that displays gray, inline suggestions as you type, based on your shell history and other strategies. It feels a lot like “typeahead” for the terminal: the moment your input matches a past command prefix, a suggestion appears and you can accept it with a key (e.g., right arrow or end-of-line). The plugin is lightweight and fast, designed to keep suggestions responsive even on large histories by performing lookups asynchronously when possible. It’s highly configurable: you can change the suggestion strategy, tweak widget bindings, ignore certain patterns, and control when suggestions appear or are cleared. The plugin plays well with other Zsh staples like syntax highlighting and prompt frameworks, and it provides guidance for avoiding conflicts with custom keymaps. -

zsh-syntax-highlighting
Fish shell like syntax highlighting for Zsh
zsh-syntax-highlighting is a lightweight Zsh plugin that adds real-time syntax coloring to your command line as you type. It highlights known commands, options, arguments, paths, strings, and glob patterns so you can catch typos or invalid commands before pressing Enter. Unknown or misspelled commands are styled differently from valid ones, making errors obvious at a glance. The plugin is written in pure Zsh and hooks into the line editor, so it doesn’t require external binaries and works across diverse environments. It’s highly configurable: you can fine-tune individual token styles, disable specific highlighters, or extend it with custom rules to match your workflow. It plays nicely with popular frameworks like Oh My Zsh, zinit, and Antigen, and it’s commonly paired with autosuggestion and prompt plugins for a complete, ergonomic shell setup. Because it focuses on correctness and speed, it remains responsive even on large histories and complex prompts. -
