Question

I need to be able to test and see if a directory exists on the SD card of an Android device and then push a few files to that directory if it does exist.

So far, I have this:

adb %argument% shell if [ -e /sdcard/ ]; then echo "it does exist"; else echo "it does not exist"; fi;

But how can I let my batch script know that the directory exists so that it can continue to push the file to that directory?

Answer 1

Here is what I have done in batch script:

set cmd="adb shell ls | find /c "theFile" "
FOR /F %%K IN (' !cmd! ') DO SET TEST=%%K
if !TEST! GTR 0 (
    echo the file exists
) else (
    echo the file does not exist
)

There could be multiple files that fit the fileName, so I chose to have it test greater than 0.

To test for exact match and using bash in Linux (reference):

FILENAME_RESULT=$(adb shell ls / | tr -d '\015'|grep '^fileName$')

if [ -z "$FILENAME_RESULT" ];
then
        echo "No fileName found."
else
        echo "fileName found."
