Question

I use the following line in my windows batch

SET MOBILE_PATH=/mnt/sdcard/koinoxrista
SET FILE_BILL="adb shell ls %MOBILE_PATH% ^| find /c "Bill.txt" "

this line adb shell ls %MOBILE_PATH% | find /c "Bill.txt" gives me 1

I want to write an If statement that will do something if FILE_BILL equals 1 and something else if equals 0. How can i do this?

if %FILE_BILL% == 1 (
    echo the file exists
) else (
    echo the file does not exist
)

I always get the message file does not exist

Answer 1

Your question makes it appear that it is only important that Bill.txt exists (or not) in a given location, and not that find /c "Bill.txt" gives 1. If that is true, then when “Bill.txt” is in the output of the adb command, you can simply use %ERRORLEVEL%:

SET MOBILE_PATH=/mnt/sdcard/koinoxrista
adb shell ls %MOBILE_PATH% | find /c "Bill.txt" >NUL
if %ERRORLEVEL% == 0 (
    echo the file exists
) else (
    echo the file does not exist
)

You can save %ERRORLEVEL% to some other variable for later use.
