The Android Operating System is built on Linux. The Terminal Emulator for Android is an app that is used to access your Android’s Linux command line shell. You may need to root your phone in order to use this program fully and some commands that you want to use may not be available. This app makes it MUCH easier to get to the info not so easily accessible on your mobile device normally.
This emulator is an open source project and thus you can expect it to change and to be updated frequently. Many users of the Terminal Emulator have used it simply to become more familiar with the file structure inside Android’s gut, err circuits. Others have said that when used in conjunction with SuperUser permissions you can change pretty much anything on your android-based phone or tablet if you know how.
Other uses include removing bloatware from factory installed settings. Many believe that this newest release is helping it to overcome a former favorite ConnectBot. Some complaints exist that some important commands don’t work, not even the clipboard but it is my understanding that there are programmers currently working on these bugs to make this the perfect terminal emulator. If you use this app in combination with one called Hacker’s Keyboard you should have easier control of all of its functions. This app is especially ideal for those with an Android tablet that have a bluetooth keyboard to be able to take full advantage of the features. Use of a keyboard would help you eliminate the issue that some have with the text getting stuck in upper case letters that some phones such as the EVO 4G LTE have problems with.
Overall we’d have to say that we do recommend the Android Terminal Emulator for those of you looking for the Linux commandline on your Android device.
