Great examples are already in the thread, but generally speaking the answer should be "no". Smart phones are just slow at typing. In the case of a smart phone, hitting a button is far faster than typing a command. Not to mention our devices aren't really being used for file management, tooling, complex work, etc. So it doesn't even make sense to have a command line unless you're a huge unix fan or if you are doing something quite niche. And in that case, I recommend just connecting via adb.
