Terminal & CLI Tools

The set of small tools that compounds into a much better shell experience for ops work.

Terminal multiplexers

• ★ tmux — universal; everywhere; the muscle-memory standard.
• ★ zellij — Rust; modern; pre-configured panes; great defaults. The most-loved newcomer.
• screen — old, ubiquitous; still works.
• byobu — wrapper around screen / tmux with friendly defaults.

Terminal emulators

• ★ Ghostty — fast, modern; growing fast in 2026.
• Alacritty — Rust; fast; minimal.
• kitty — fast; many features.
• WezTerm — Lua-configurable; cross-platform.
• iTerm2 (Mac) — long-running classic.
• Windows Terminal (Microsoft) — finally good.
• Warp — AI-flavored terminal; commercial.

Shell

• bash — default; everywhere.
• ★ zsh + oh-my-zsh / prezto / zinit — many plugins; great defaults.
• fish — friendly; great defaults out of the box; some POSIX deviations.
• nushell — structured-data shell; pipes are typed.

Prompt

• ★ Starship — Rust; fast; cross-shell; the default in 2026.
• Powerlevel10k (zsh) — feature-rich; very fast.
• Oh My Posh — same niche, cross-shell.
• liquidprompt — older, simpler.

Modern replacements for common Unix tools

• ★ ripgrep (rg) — replaces grep; way faster.
• ★ fd — replaces find; sane defaults.
• ★ bat — replaces cat; syntax highlighting + line numbers.
• ★ eza — replaces ls; colors + tree mode.
• dust — replaces du; visual.
• duf — replaces df; tables.
• procs — replaces ps; tree view.
• sd — replaces sed for common cases.
• delta — better git diff viewer.
• xh / httpie — better curl for HTTP.
• jq / yq — JSON / YAML query.
• gron — make JSON grep-able.
• jless — interactive JSON viewer.

Fuzzy / interactive

• ★ fzf — universal fuzzy finder; pipe anything to it. Life-changing.
• skim (sk) — Rust alternative to fzf.
• zoxide — fuzzy cd based on frecency. Replaces cd.
• autojump / z — older zoxide ancestors.

Editors (terminal-side)

• ★ vim / Neovim — universal.
• ★ Helix — modern Kakoune-style modal editor; great defaults.
• nano — the editor your EDITOR defaults to when SSH'd.
• micro — friendlier alternative to nano.

File transfer / copying

• See File Sync — rsync, rclone, croc, magic-wormhole.

Productivity glue

• direnv — auto-load env when you cd into a project.
• mise — runtime version manager; see Dev Environments.
• just — modern command runner; like make for tasks.
• Taskfile — same niche, YAML config.
• lazygit — TUI for git.
• gh — GitHub CLI.
• glab — GitLab CLI.

Patterns to adopt

• ★ Aliases for kubectl, git, docker, ssh. Save thousands of keystrokes.
• fzf history search — Ctrl+R becomes magical with fzf's history widget.
• Starship for a consistent prompt across machines / shells.
• Persistent tmux session per host — reconnect to the same workspace after disconnects.
• mosh + tmux for flaky connections.

Pick this if…

• Default modern shell setup: zsh + Starship + fzf + zoxide + ripgrep + fd + bat + eza.
• Multiplexer: tmux (mature) or zellij (modern).
• Terminal emulator: Ghostty or Alacritty.
• Fast modal editor: Helix.
• Shell-script-like tasks: just or Taskfile.
• TUI git: lazygit.
