SSH Button is a free Android application that enables users to send SSH commands to Linux hosts through a button on their Android device. With this app, you can create a new button and add the command you want to send to the Linux device. The app allows you to specify various parameters for each button, including label, command, IP address or hostname, username, password, private key (optional), and SSH port.

One of the best things about SSH Button is that it enables you to execute Linux/Unix commands that return immediately. With this app, you can easily send commands like 'sudo reboot' or 'sudo service httpd restart' with just a tap. The interface is user-friendly and easy to navigate, making it a great tool for both beginners and advanced users.
