No, it won't. It only looks like it's like reopening the terminal, it won't reload your configs and stuff. Instead of writing "clear", you can do ctrl + r to achieve the same thing.

If you instead really want your terminal to be like reopened, do "reset" instead.

Regarding the history command, combining it with grep is when it becomes really useful. Example, all my latest git commands:

history | grep -i "git"

C-r will (usually?) invoke reverse-search-history (http://www.gnu.org/software/bash/manual/html_node/Commands-F...) in bash (and I'm sure some other shells also).

That is absolutely true. I meant super + r.

No, I didn't but that's pretty handy since it doesn't hide the new prompt.

Agreed, and clear won't help if you accidentally cat some binary code and put the terminal into "goofy symbols mode". In that case it's important to remember the reset command, especially if there's something vital running in that terminal and you can't just kill it.

But ctrl-r in bash starts a reverse history search, which is also very useful. It doesn't clear the screen, at least not the way it's configured on my linux machines.
