Free open-source app Hotwire is a GUI-based terminal with auto completion. Hotwire has most of the functionality of the bash shell tucked into an easy-to-use GUI. Intended to replace the Linux terminal, Hotwire is perfect for Linux beginners. Hotwire is a perfect way for new users to dip a toe into the terminal without diving in head first. Hotwire is a free download for Linux only. Ubuntu users can install Hotwire using:
sudo apt-get install hotwire
*Hotwire isn't in the Ubuntu repository. You have to download the .deb file from getdeb.net and install it manually.
This is also for Windows. See hotwire-shell.org
