Standalone binary package for executing commands on an Android device with handy shell and shorthands for most popular commands. Binaries are taken from Android SDK.
Run adbshell.bat and input your commands. You may use shorthands for popular commands. Get the current list of them printed out by executing adbshell.bat /?.
Tip: you can create a Windows shortcut to adbshell.bat name it adb or adbs and place it somewhere in the %PATH%. Thus you'll always have ADB shell at hand with WinKey + R > adb > Enter.
These are usual batch files containing a single line. That line is printed out when you execute adbshell.bat /? so if you use more lines you'll get the shorthands list output quite messed up.
