"The same can be achieved by tput command,

$ tput clear"

Or you can just use the "clear" command

$ clear

It's also worth mentioning that this doesn't really clear the screen on terminal windows, just scrolls the window by enough lines to make it look cleared. If you scroll back up, you'll still see the old content.

It actually depends on your terminal. clear, which internally does the same as tput clear, outputs the CSI 2 J escape sequence that instructs the terminal to erase the data on the screen. There may or may not be line scrolling depending on terminal capabilities.
