Command Line Cheetsheets

!Cheatsheets_README.md

Cheatsheets

for bash, git and various command line utilities

Access the cheatsheets directly in CLI just with one command - no need to go somewhere else and switch context, get the hint where you need it.

Prerequisites

Before using these cheatsheets, ensure you have the following installed:

Required

• Bash/Zsh/compatible shell - Standard on macOS/Linux, available on Windows via WSL or Git Bash
• Git - For git commands in .git_cheat
• GitHub CLI (gh) - For GitHub authentication commands (install from cli.github.com)

Optional (for some commands)

• fzf - Fuzzy finder for interactive file selection (install: brew install fzf on macOS, apt install fzf on Linux)
• tree - Directory tree viewer (brew install tree / apt install tree)
• VS Code - For code command functionality
• Common Lisp / SBCL - For translation functions in .cheatsheet (if you use those features)
• translate-shell - For trans command (install from github.com/soimort/translate-shell)
• Node.js - For node commands in bash cheatsheet
• Python 3 - For HTTP server and other Python commands

Setup Instructions

1. Clone or download the cheatsheet files to ~/Bash/ directory

mkdir -p ~/Bash
# Place .cheatsheet, .bash_cheat, and .git_cheat in ~/Bash/

2. Add aliases to your shell configuration file: macOS (Bash): ~/.bash_profile Linux (Bash): ~/.bashrc macOS/Linux (Zsh): ~/.zshrc Windows (Git Bash): ~/.bash_profile or ~/.bashrc

alias ?='echo "💡 Quick: open \"\$(find . -name \"*.pdf\" | fzf)\" | Full: cheat"'
alias cheat='cat ~/Bash/.cheatsheet'
alias bash_cheat='cat ~/Bash/.bash_cheat'
alias git_cheat='cat ~/Bash/.git_cheat'

3. Reload configuration

source ~/.bash_profile      # Use your own configuration file name
   # or: source ~/.bashrc
   # or: source ~/.zshrc

4. Test the aliases in bash shell:
   cheat - shows a common generic cheatsheet,
   bash_cheat - shows popular bash commands description,
   git_cheat - shows popular git commands description.
   ? - quick helper (requires fzf for file finder)

Notes

• The ? alias requires fzf to be installed for interactive file selection
• Small one-line alias like ? do not require a separate files and can be defined in the shell configuration file
• File paths assume cheatsheets are stored in ~/Bash/ - adjust paths in aliases if you use a different location
• Windows users should use Git Bash or WSL for best compatibility
• Some commands (like open) are macOS-specific; use explorer on Windows or xdg-open on Linux

Term	Description
Terminal	A visual interface or app that gives you access to a shell (e.g., Terminal.app on macOS, GNOME Terminal on Linux, Windows Terminal). Think of it as the "window" or "UI."
Command Line (CLI)	The actual interface you type commands into — the "line" where commands are entered (e.g., Bash, Zsh, CMD, PowerShell)
