	Name:   "exec",
	Short:  "Run the provided adb command on all devices and emulators concurrently",
	Long: `
Runs the provided adb command on all devices and emulators concurrently.

For example, the following line:

    madb exec push ./foo.txt /sdcard/foo.txt

copies the ./foo.txt file to /sdcard/foo.txt for all the currently connected devices.

There are a few pre-defined keywords that can be expanded within an argument.

    "{{index}}"  : the index of the current device, starting from 1.
    "{{name}}"   : the nickname of the current device, or the serial number if a nickname is not set.
    "{{serial}}" : the serial number of the current device.

For example, the following line:

    madb exec -n=Alice,Bob push ./{{name}}.txt /sdcard/{{name}}.txt

copies the ./Alice.txt file to the device named Alice, and ./Bob.txt to the device named Bob.
Note that you should type in "{{name}}" as-is, with the opening/closing curly braces, similar to
when you're using a template library such as mustache.
