Is there any undo command for clear in Linux?

Question

I accidentally cleared my screen and I need to see my previous output, any way to see output/results of previous commands? I understand that I can see my past commands using history command but I am not looking for that

Most terminal emulators implement clearing by simply scrolling down until the prompt is at the top. — Panki, Dec 20 '19 at 08:06
Are you talking about a terminal emulator? If so, which one? Does Alt+PgUp let you scroll up to the past commands? How did you clear your screen? Did you just run clear? Please [edit] your question and explain what you need in more detail. — terdon, Dec 20 '19 at 09:04
Does this answer your question? How can we undo the clear command in Linux? — GAD3R, Feb 05 '22 at 16:26

You can use !!. This command prints the output of the last command you ran. For example:

me@dev:~$ cat test.txt
This is the test file.

And i cleared my screen.. Then i ran the !! command. And output is here:

me@dev:~$ !!
cat test.txt
This is the test file.

Look here for more..

NOTE: You shouldn't use clear while clean your screen, instead you should use Ctrl+L because terminal remembers clear as the last command.
