To check the running LineageOS version from Termux, you can use standard Android shell commands. Here are the most reliable methods:

---

1. Check Build Prop

Run this command in Termux to extract the LineageOS version from the system properties:

bash
Copy
getprop ro.lineage.version

or

bash
Copy
getprop ro.modversion

This will return the LineageOS version (e.g., 18.1, 20, etc.).

---

2. Check Android Version (Fallback)

If the above doesn't work, you can check the Android version, which often matches the LineageOS base:

bash
Copy
getprop ro.build.version.release

This will show the Android version (e.g., 11, 12, 13), which corresponds to LineageOS 18.1, 19, 20, etc.

---

3. Check Full Build Info

For more details, use:

bash
Copy
getprop ro.build.display.id

This will show something like lineage_<device>-userdebug 11 RQ3A.211001.001 eng.<builder>.20230101.000000 dev-keys, where 11 is the Android version.

---

4. Check LineageOS Updater (if available)

If your device has the LineageOS Updater app, you can also check its logs or run:

bash
Copy
su -c "pm list packages | grep updater"

Then inspect the updater app's version or logs for the OS version.

Note:

• You may need root access (su) for some commands.
• If you don’t have getprop, ensure Termux has access to Android’s shell environment.
