Android is undoubtedly a great operating system. A wide variety of devices, an easy-to-use interface, and relatively low device prices make Google’s system the first “smart” operating system. Android is almost complete. It allows you to tap like a maniac to squeeze a bird between two pipes or inhale your daily dose of Android news. This Linux-based OS doesn’t offer many things that GNU has to offer, but luckily the development-fu is strong on XDA. Because of the aftermarket communities, this small operating system can be given some serious Unix power.
Not too long ago, we talked about GNU CoreUtils as an alternative to Busybox. The developer responsible for that tool, XDA Senior Member alireza7991, decided to expand his project a bit and make the source for the most common tools public. Tools like grep, wget or make are compiled with GCC 4.8.1/4.8.2 toolchain and optimized to get the best performance. If you are planning to test them, simply download the package, unzip it, and push it to /system/xbin with ADB or your favorite root-based file explorer.
More information about the project and a complete list of tools can be found in the original thread, so please go there and give it a try._________
