grepcommand is not installed on your device by default. If you need to use grepcommand in your device, you can cross-compile busyboxthen invoke grepunder busybox.
grep默认情况下，您的设备上未安装命令。如果您需要grep在您的设备中使用命令，您可以交叉编译busybox然后grep在busybox.
However if you are in Linuxor Cygwin, you can pipe the command output and use the grepin PC to get result you want, e.g.
但是，如果您在Linux或 中Cygwin，则可以通过管道grep传输命令输出并使用in PC 来获得您想要的结果，例如
$ adb shell ps |grep google
