ADB 上传文件并使用脚本监控上传百分比

article 2024/12/27 12:47:17

有个需求，需要测试 emmc的外部连续写入性能，使用 ADB 上传一个巨大的文件。并且在上传到一定值时进行干预。

因此但是 adb push 命令本身会 block 运行并且不返回进度，因此需要一个额外的监控脚本。

上传脚本：

@echo off
setlocal enabledelayedexpansion

set COUNTER=0
set TARGET_DEVICE=xxx
set ISO_FILE=C:\Users\xxx\Desktop\1.iso
set DEST_PATH=/sdcard/1

:READ
echo Pushing ISO file on round ...
adb -s %TARGET_DEVICE% push %ISO_FILE% %DEST_PATH%
if errorlevel 1 (
    echo Push failed, retrying...
    goto READ
)
echo File pushed successfully.

adb -s %TARGET_DEVICE% shell rm %DEST_PATH%
if errorlevel 1 (
    echo Remove failed, retrying...
    goto READ
)
echo File removed successfully.

set /a COUNTER+=1
echo Number of successful operations: !COUNTER!

:: 等待 5 秒
timeout /t 5 > nul
exit

监控脚本

@echo off
setlocal enabledelayedexpansion

:: 这里设置目标设备、目标路径和源文件路径
set TARGET_DEVICE=xxx
set DEST_PATH=/sdcard/1
set ISO_FILE=C:\Users\xxx\Desktop\1.iso

:: Get the total size of the ISO file
for %%F in ("%ISO_FILE%") do set TOTAL_SIZE=%%~zF

:MONITOR_PROGRESS
:: Check the size of the file on the device
::echo 读取文件大小
adb -s %TARGET_DEVICE% shell ls -l %DEST_PATH% > tempfile.txt

if errorlevel 1 (
    echo Failed to get file size.
    exit /b
)


:: 从 tempfile.txt 中提取文件大小
for /f "tokens=4" %%S in (tempfile.txt) do (
    set TRANSFERRED_SIZE=%%S
)

::set /a 命令仅支持 32 位整数，这意味着它不能处理超过 2147483647 的数值
:: 批处理默认的set /a 变量=算式 的结果要在[-2147483647，2147483647]这个范围，超过了会给异常提示
echo.
:: 计算并显示进度百分比
echo TRANSFERRED_SIZE=!TRANSFERRED_SIZE! TOTAL_SIZE=!TOTAL_SIZE!

:: 如果无法读取转移大小，则输出错误信息
if "!TRANSFERRED_SIZE!"=="" (
    echo Could not read the transferred file size. It may not exist yet.
) else (
	:: 使用 PowerShell 进行比较和计算
    for /f %%i in ('powershell -command "[double]!TRANSFERRED_SIZE! -lt [double]!TOTAL_SIZE!;"') do set "result=%%i"
	echo result=!result!
	
	if "!result!"=="True" (
		for /f "delims=" %%p in ('powershell -command "[math]::Round((%TRANSFERRED_SIZE% -as [double]) / (%TOTAL_SIZE% -as [double]) * 100, 2)"') do set PERCENTAGED=%%p
		echo 传输百分比: !PERCENTAGED!
		:: 睡眠一秒
		timeout /t 1 > nul
		:: 开启下次循环
		goto MONITOR_PROGRESS
    ) else (
        echo Progress: 100%
    )
)


:: Clean up
del tempfile.txt
echo Transfer completed successfully.
pause
