I want to push some files of the same type (
adb push *.img /sdcard/
*.img files to an empty directory, then push the directory (
adb push /tmp/images /storage/sdcard0).
adb will push all files in that directory to your designated location.
/sdcard as a path has been obsolete for quite some time, so please make sure you use a destination that exists and is supported by your device. Most Android 2.x/3.x/4.0 devices use
/mnt/sdcard; Android 4.1 uses
