Output

[RGeB]

Is there any way in Automate to view or save the results (output) of an adb shell (privileged shell) command like dumpsys power? I have tried commands dumpsys power > test.txt and dumpsys power > download/test.txt and dumpsys power > sdcard/test.txt, but I cannot find any such file.  ADB shell dumpsys power works in Win, and the Automate log shows no errors, so I assume my problem in Automate is on the output side. I cannot find anything relevant on “output” in the Automate documentation or forum.

Assign the Standard output text variable a then use the File write block, e.g.:

1. Flow beginning
2. Shell command privileged: Command line=dumpsys power, Standard output text=stdout
3. File write: File=<click to pick>, Content=stdout

As for piping, as the documentation say, "Currently the command isn’t executed in actual shell, e.g. bash, so built-in commands without stand-alone executables like cd, echo and test may not work, nor may “piping”, e.g. | or >, without wrapping the command in sh -c "command""

Thanks, but this gives a file containing one word: stdout. I must be missing something. Any suggestions?

(Not sure what is meant by:  wrapping the command in sh -c "command""; so I have not tried that.)

In the Content field, click the fx button then type in the variable name. Please read:

To use piping, i.e. > you need to wrap the command line like:

sh -c "dumpsys > test.txt"

Thanks again. Both ways work. 

In case anyone else is dumb like me (I would never have worked it out from the Documentation) the methods are:

Either

1. Flow beginning
2. Shell command privileged:: Input arguments, Command line=dumpsys power; Output variables, Standard output text=stdout
3. File write:: File=<click to pick, eg Download/test.txt > (requires granting write permission); In Content,  click the fx button then type in stdout (don't use " ")

Or

1. Flow beginning
2. Shell command privileged:: Command line=sh -c "dumpsys power >test.txt"

The files may go to different places, but you can find them using a capable file manager (like MiX).
