Well, if you are someone who often run few terminal commands, then a new root enabled app called “Quick Terminal” might be handy. As said, the app require root access to your device and once installed, you can quickly execute terminal commands. Quick Terminal comes with pre-loaded commands such as rebooting your device (including rebooting into recovery or boot loader), changing MAC address, signal checking, disable MediaScan on Boot, wipe Dalvik Cache and resetting WiFi. Moreover you can easily customize the quick terminal to your liking. It means you can change it to use most commonly used commands and add your own scripts via the MyScripts panel.
Download Quick Terminal from original thread on XDA.
Note: If you were facing any problem with the device, then remove the QuickTerminal folder in the sdCard and try again.
