This cool hack uses the terminal capabilities (see ''terminfo(5)'' manual) **smcup** and **rmcup** to save and restore the terminal content.

For sure, you’ve already seen those programs that restore the terminal contents after they did their work (like ''vim'').

<code>
|
|||
|
|
# save, clear screen
|
|||
|
|
tput smcup
|
|||
|
|
clear
|
|||
|
|
|
|||
|
|
# example "application" follows...
|
|||
|
|
read -n1 -p "Press any key to continue..."
|
|||
|
|
# example "application" ends here
|
|||
|
|
|
|||
|
|
# restore
|
|||
|
|
tput rmcup
|
|||
|
|
</code>
