ctop shows container metrics similar to top for processes.

Developer AliasesLink to heading

Here are my most important aliases from daily development work:

Git ShortcutsLink to heading

# Git aliases
alias g="git"
alias gp="git push"
alias gf="git fetch"
alias gpu="git pull"
alias gch="git checkout"
alias gfork="open -a fork ."    # Open Fork app (macOS)

General ProductivityLink to heading

# Quick access
alias o="open"                  # Open file/folder (macOS)
alias s="subl"                  # Sublime Text

# Navigation
alias ..="cd .."
alias ...="cd ../.."
alias ....="cd ../../.."

Development EnvironmentsLink to heading

# Python
alias python=/usr/local/bin/python3.6
alias pip=/usr/bin/pip3

Advanced ToolsLink to heading

z - Intelligent NavigationLink to heading

z remembers visited directories and enables fast navigation:

# Installation
git clone https://github.com/agkozak/zsh-z ~/.zsh-plugins/zsh-z
echo 'source ~/.zsh-plugins/zsh-z.plugin.zsh' >> ~/.zshrc

# Usage
z project    # Jump to ~/dev/project
z doc        # Jump to ~/Documents

xcodes - Xcode Version ManagerLink to heading

Yes we all love and hate Xcode at the same time. Managing multiple Xcode versions is painful through the App Store. xcodes makes it simple:

# Installation
brew install xcodesorg/made/xcodes

# List available versions
xcodes list

# Install a specific version
xcodes install 26.3

# Switch active Xcode version
xcodes select 26.3

xcodes is significantly faster than downloading through the App Store and lets you keep multiple versions installed side by side, essential when working on projects with different Xcode requirements. It’s also usefull to install beta versions of Xcode without affecting your stable version.

direnv - Project-Specific EnvironmentsLink to heading

direnv allows you to set environment variables on a per-project basis. When you cd into a directory with an .envrc file, direnv automatically loads the environment variables defined in that file. This is perfect for setting up project-specific configurations without polluting your global environment.

# Installation
brew install direnv

# In ~/.zshrc
eval "$(direnv hook zsh)"

# Usage: .envrc in project folder
echo 'export NODE_ENV=development' > .envrc
direnv allow

ConclusionLink to heading

These tools and aliases transform the terminal from a necessary tool into a productive and enjoyable work environment. The key is to start small and gradually integrate the tools.

My Top 5 Recommendations:Link to heading

1. z - Intelligent navigation
2. eza - Better ls with Git integration
3. bat - cat with syntax highlighting
4. fzf - Fuzzy finding for everything
5. lazydocker - Docker management

🔧 Tip: Start with 2-3 tools and get used to them before adding more. Muscle memory takes time!
