How to list all the files in android phone by using adb shell?

This command will show also if the file is hidden adb shell ls -laR | grep filename

I might be wrong but "find -name __" works fine for me. (Maybe it's just my phone.) If you just want to list all files, you can try

adb shell ls -R /

You probably need the root permission though.

Edit: As other answers suggest, use ls with grep like this:

adb shell ls -Ral yourDirectory | grep -i yourString

eg.

adb shell ls -Ral / | grep -i myfile

-i is for ignore-case. and / is the root directory.

just to add the full command:

adb shell ls -R | grep filename

this is actually a pretty fast lookup on Android

Open cmd type adb shell then press enter. Type ls to view files list.
