The Homebrew package manager may be used on Linux and [Windows Subsystem for Linux (WSL)](https://docs.microsoft.com/en-us/windows/wsl/about). Homebrew was formerly referred to as Linuxbrew when running on Linux or WSL. It can be installed in your home directory, in which case it does not use *sudo*. Homebrew does not use any libraries provided by your host system, except *glibc* and *gcc* if they are new enough. Homebrew can install its own current versions of *glibc* and *gcc* for older distributions of Linux.
[Features](#features), [dependencies](#dependencies) and [installation instructions](#install) are described below. Terminology (e.g. the difference between a Cellar, Tap, Cask and so forth) is [explained in the documentation](Formula-Cookbook.md#homebrew-terminology).
## Features
+ Can install software to your home directory and so does not require *sudo*
+ Install software not packaged by your host distribution
+ Install up-to-date versions of software when your host distribution is old
+ Use the same package manager to manage your macOS, Linux, and Windows systems
## Install
Paste at a terminal prompt:
```sh
sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"
The installation script installs Homebrew to `/home/linuxbrew/.linuxbrew` using *sudo* if possible and in your home directory at `~/.linuxbrew` otherwise. Homebrew does not use *sudo* after installation. Using `/home/linuxbrew/.linuxbrew` allows the use of more binary packages (bottles) than installing in your personal home directory.
Follow the *Next steps* instructions to add Homebrew to your `PATH` and to your bash shell profile script, either `~/.profile` on Debian/Ubuntu or `~/.bash_profile` on CentOS/Fedora/RedHat.
If you're using an older distribution of Linux, installing your first package will also install a recent version of `glibc` and `gcc`. Use `brew doctor` to troubleshoot common issues.
Homebrew can run on 32-bit ARM (Raspberry Pi and others) and 64-bit ARM (AArch64), but no binary packages (bottles) are available. Support for ARM is on a best-effort basis. Pull requests are welcome to improve the experience on ARM platforms.
Homebrew does not currently support 32-bit x86 platforms. It would be possible for Homebrew to work on 32-bit x86 platforms with some effort. An interested and dedicated person could maintain a fork of Homebrew to develop support for 32-bit x86.
