After even one ls command in a shell prompt, the
terminal window you are working in can begin to look crowded. You can
always exit from the terminal window and open a new one, but there is a
quicker and easier way to clear the contents displayed in the terminal.
Try typing the command clear at the shell prompt. The
clear command does just what it implies: it clears the
terminal window.
Sometimes, you may accidentally open a program file or some other
non-text file in a terminal window. Once you close the file, you could
find that the text you are typing does not match the output on the
monitor.
In such cases, type reset to return the terminal
window to its default values.
