The code you provided is a batch script that includes a loop. It executes a series of commands for each iteration of the loop. Let's break down the code:
```
for /l %%i in (1,1,1000) do (
@echo ********************* the %%i times**********************
@ adb shell reboot
@ ping -n 60 127.0.0.1 >nul
)
```
This code uses a `for /l` loop, which iterates from 1 to 1000 with a step size of 1 (`(1,1,1000)`). For each iteration, the commands within the `do` block are executed.
Inside the loop:
1. `@echo ********************* the %%i times**********************` prints a line that includes the value of `%%i`, where `%%i` represents the current iteration number. The double percent signs (`%%`) are used to escape the single percent sign and represent the variable `%%i`.
2. `@ adb shell reboot` executes the command `adb shell reboot` in the command prompt. This command is typically used to reboot an Android device connected to the computer via ADB (Android Debug Bridge).
3. `@ ping -n 60 127.0.0.1 >nul` pings the loopback address (`127.0.0.1`) 60 times (`-n 60`). The output of the ping command is redirected to the null device (`>nul`), effectively discarding the output.
This code seems to be intended for automating a sequence of tasks that involve rebooting an Android device connected via ADB and waiting for a specific period (60 seconds) between iterations.
Please note that running ADB commands or pinging in a loop can have implications, so make sure to use the script responsibly and in accordance with your specific requirements.
