Clear terminal using keyboard shortcut

In gnome terminal, you can edit the keyboard shortcuts with Edit -> Reset Shortcuts... You can then map the command "Reset and Clear", which seems to do what you're looking for.

Alternatively, you can limit the scrollback history to a small number (say 0) and Ctrl+L will be closer to what you are looking for.

• CTRL+u clears from cursor to beginning of line

• CTRL+k clears from cursor to end of line

• CTRL+d clears one character to the right of the cursor

• Esc+Backspace clears one word to the left of the cursor

• Esc+d clears one word to the right of the cursor

• Alt+left/right jumps to the beginning of the previous/next word

• Ctr+a jumps to start of line

• Ctr+e jumps to end of line

To clear the entire screen add the following alias to your ~/.bashrc file:

alias cls="echo -ne '\033c'"

Now, in a new terminal typing cls will clear everything including the scroll buffer. It works much faster than reset since it does not reset anything.

In fact reset is only needed when you want to fix a broken terminal, e.g. after running cat on a binary file.

If you are on OSX, then Command (⌘)+k will clear the terminal _{(also works in the chrome devtools console)}.

Ctrl+L redraws the terminal; it doesn't clear it. If you're in a full-screen app like less or vim, the Ctrl-L command is what you use to redraw a corrupted screen. In vim with color syntax highlighting, for example, you can use ctrl_l to update the colors if you scroll a long distance and vim gets confused by matching quotes or brackets or similar.

Just for reference if someone searches and finds this... If you need to clear the scroll-back buffer, either set your buffer to 0 lines or close the window and reopen it. Or "while true; do print; done" and then interrupt with ctrl+c when you've output enough lines to blow the buffer. The scroll buffer is application dependent, so while the given solution works for Gnome terminal, it won't work for really any other terminal device.
