Z2Term is a terminal for Android that is also a way to drive Android. It runs Alpine, Ubuntu, Arch and Kali without root, opens a Linux desktop in a tab, and lets the shell reach the phone itself: read a notification, ask you a question in the notification shade, or run a script when the battery, the network or an incoming SMS changes. * Linux distributions without root: z2root is a ptrace-based userspace implementation written for this app and built from source. A real chroot is optionally available on rooted devices. * Terminal emulator: VT100/xterm, 256-colour and true colour, alternate screen, East Asian Width (CJK / emoji) rendered as 2 cells, OSC 4/7/8/10/11/12/52 * 9 built-in themes plus a custom theme editor, and custom font loading * 5,000-line scrollback (configurable 500-50,000) with search * Multi-tab sessions with independent emulators, drag to reorder * Linux GUI: Xvnc + openbox with an RFB client built into the app, with audio and video. "z2gui" starts a desktop, "z2run <app>" launches a GUI program. The same screen also connects to another machine over VNC or RDP. * SSH client and SFTP built in (public-key auth, secrets encrypted by the Android Keystore), port forwarding in both directions that can outlive the tab, plus a built-in sshd that binds to localhost only by default * Android bridge: around 40 "z2-*" helpers call host features from the shell (notifications, clipboard, battery, sensors, torch, intents, alarms, text-to-speech, and wireless adb to the device itself) * It can ask you things: "z2-ask" puts a question in the notification shade and reads your reply into a shell variable * Automation hub: "z2-when" runs scripts on device events (charging, battery level, time or cron, Wi-Fi, connectivity, boot, a share from another app, an incoming SMS, sensors, an arriving notification, a new file), narrowed by filters. Rules are plain text and survive reboots without opening the app. * Resident servers: register any server as a start command and
