# x env - Environment & Package Manager ## Prerequisites 1. Load x-cmd before use: ```bash . ~/.x-cmd.root/X ``` 2. x-cmd not installed? → [data/install.md](data/install.md) ## Core Concepts - **try**: Temporarily use software in current shell session (only valid for current terminal) - **use**: Permanently install software to user environment (persists after terminal restart) - **untry**: Cancel temporarily tried software in current session - **unuse**: Remove installed software from user environment - **upgrade**: Upgrade installed software versions ## Core Functions - **List available versions**: `x env la <pkg>` - **List installed packages**: `x env ls`, `x env ll` - **Temporary use (try)**: `x env try <pkg>[=<version>]` - **Permanent install (use)**: `x env use <pkg>[=<version>]` - **Remove package**: `x env unuse <pkg>` - **Upgrade package**: `x env upgrade <pkg>` - **Cleanup packages**: `x env gc <pkg>` - **Find command path**: `x env which <cmd>` - **Check dependencies**: `x env depend <pkg>` ## Usage Examples ### Install packages ```bash x env use node # Install default version of node x env use python # Install default version of python x env use go=v1.21.0 # Install specific version x env use node python go # Install multiple packages ``` ### Temporary use (current shell session only) ```bash x env try node # Use default node in current session x env try bun go=v1.17.13 # Use multiple packages with versions x env untry node # Cancel temporary use ``` ### Version management ```bash x env use --upgrade --all # Upgrade all installed packages x env use --upgrade jq yq # Upgrade specific packages x env upgrade node python # Upgrade packages (shorthand) ``` ### List and search ```bash x env la node # List all available node versions x env ls # List packages in use x env ll # List all installed packages x env which node # Show node installation path ``` ### Cleanup ```bash x env gc jq yq # Remove specified packages and orphans ``` ## Common Scenarios - **Install node**: `x env use node` - **Install python**: `x env use python` - **Install go**: `x env use go` - **Install jq**: `x env use jq` - **Install specific version**: `x env use node=v18.12.0` - **Temporary try**: `x env try node` - **Upgrade all**: `x env upgrade --all` - **Find path**: `x env which node` ## Get Help Run `x env --help` for full help documentation.
