micro is a terminal-based text editor that aims to be easy to use and intuitive, while also taking advantage of the capabilities of modern terminals. It comes as a single, batteries-included, static binary with no dependencies; you can download and use it right now!
As its name indicates, micro aims to be somewhat of a successor to the nano editor by being easy to install and use. It strives to be enjoyable as a full-time editor for people who prefer to work in a terminal, or those who regularly edit files over SSH.
Here is a picture of micro editing its source code.
To see more screenshots of micro, showcasing some of the default color schemes, see here.

Installation
To install micro, you can download a prebuilt binary, or you can build it from source.
If you want more information about ways to install micro, see this wiki page.
Prebuilt binaries
All you need to install micro is one file, the binary itself. It’s as simple as that!
Download the binary from the releases page.
On that page you’ll see the nightly release, which contains binaries for micro which are built every night, and you’ll see all the stable releases with the corresponding binaries.
Running micro -version will give you the version information.
Installation script
There is a script which can install micro for you by downloading the latest prebuilt binary. You can find it at https://getmic.ro.
You can easily install micro by running
curl https://getmic.ro | bash
The script will install the micro binary to the current directory. See its GitHub repository for more information.
Package managers
You can install micro using Homebrew on Mac:
brew install micro
On Linux, you can install micro through snap
snap install micro --classic
On Debian unstable | testing | buster-backports and Ubuntu focal (20.04), micro is available
via apt:
sudo apt install micro
Micro is also available through other package managers on Linux such as AUR, Nix, and package managers for other operating systems:
- Windows: Chocolatey and Scoop
choco install microscoop install micro
- OpenBSD: Available in the ports tree and also available as a binary package
pkd_add -v micro
- Arch Linux, CRUX, Termux for Android
- See details in the wiki page
Building from source
If your operating system does not have a binary release, but does run Go, you can build from source.
Make sure that you have Go version 1.11 or greater and Go modules are enabled.
git clone https://github.com/zyedidia/micro
cd micro
make build
sudo mv micro /usr/local/bin # optional
The binary will be placed in the current directory and can be moved to
anywhere you like (for example /usr/local/bin).
The command make install will install the binary to $GOPATH/bin or $GOBIN.
You can install directly with go get (go get github.com/zyedidia/micro/cmd/micro) but this isn’t
recommended because it doesn’t build micro with version information (necessary for the plugin manager),
and doesn’t disable debug mode.
Fully static binary
By default, the micro binary will dynamically link with core system libraries (this is generally
recommended for security and portability). However, there is a fully static prebuilt binary that
is provided for amd64 as linux-static.tar.gz, and to build a fully static binary from source, run
CGO_ENABLED=0 make build
macOS terminal
If you are using macOS, you should consider using iTerm2 instead of the default terminal (Terminal.app). The iTerm2 terminal has much better mouse support as well as better handling of key events. For best keybinding behavior, choose xterm defaults under Preferences->Profiles->Keys->Load Preset. The newest versions also support true color.
If you still insist on using the default Mac terminal, be sure to set Use Option key as Meta key under
Preferences->Profiles->Keyboard to use option as alt.
Linux clipboard support
On Linux, clipboard support requires:
- On X11, the
xcliporxselcommands (for Ubuntu:sudo apt install xclip) - On Wayland, the
wl-clipboardcommand
If you don’t have these commands, micro will use an internal clipboard for copy and paste, but it won’t work with external applications.
Colors and syntax highlighting
If you open micro and it doesn’t seem like syntax highlighting is working, this is probably because
you are using a terminal which does not support 256 color mode. Try changing the color scheme to simple
by pressing Ctrl+E in micro and typing set colorscheme simple.
If you are using the default Ubuntu terminal, to enable 256 make sure your TERM variable is set
to xterm-256color.
Many of the Windows terminals don’t support more than 16 colors, which means
that micro’s default color scheme won’t look very good. You can either set
the color scheme to simple, or download and configure a better terminal emulator
than the Windows default.
Cygwin, Mingw, Plan9
Cygwin, Mingw, and Plan9 are unfortunately not officially supported. In Cygwin and Mingw, micro will often work when run using
the winpty utility:
winpty micro.exe ...
Micro uses the amazing tcell library, but this means that micro is restricted to the platforms tcell supports. As a result, micro does not support Plan9, and Cygwin (although this may change in the future). Micro also doesn’t support NaCl (which is deprecated anyway).
Usage
Once you have built the editor, start it by running micro path/to/file.txt or micro to open an empty buffer.
micro also supports creating buffers from stdin:
ifconfig | micro
You can move the cursor around with the arrow keys and mouse.
You can also use the mouse to manipulate the text. Simply clicking and dragging will select text. You can also double click to enable word selection, and triple click to enable line selection.
Documentation and Help
micro has a built-in help system which you can access by pressing Ctrl+E and typing help. Additionally, you can
view the help files here:
I also recommend reading the tutorial for a brief introduction to the more powerful configuration features micro offers.
