+## Ejemplo
+
+```bash
+android_shell pm list packages
+android_shell --serial emulator-5554 getprop ro.product.model
+android_shell df -h /sdcard
+android_shell ls -la /data/local/tmp
+```
+
+## Notas
+
+Sourcea `adb_wsl.sh` para resolver `adb_pick_serial` (maneja `--serial`, `ADB_SERIAL`, y auto-detect de dispositivo unico) y `adb_s` (wrapper de `adb -s`). El array `ADB_PICK_REST` contiene los args restantes tras consumir `--serial`.
+
+Para comandos con pipes o redirects que bash interpretaria localmente, mejor pasar como string unico: `adb_s "$serial" shell 'cmd | grep foo'`.
