I just found that the current command line will be cleared when trying to input the "@" sign to the terminal. I checked current alias, but found nothing.
Would you please provide some suggestion about it?

Hi.
Historical aside: the @ symbol was at one time often the choice for (line) kill:
Quote:
You can also erase or kill, an entire line. If a line is so hopelessly messed up that erasing characters is more trouble than starting over, you can type in an at sign (@). This causes everything typed before the @ to be ignored and starts you on a new line (but does not display a new prompt).

Most commonly these days I have seen Control-U (sometimes written as ^U in stty output) used for that feature. Things have come a long way since 1990. These days we can usually edit the line interactively.
As Jim said, you can probably see what this is with stty -a, and possibly use that to fix it as well. There are a lot of confusing symbols and terms in man stty but that's the first place I would look.
Here's a fragment from my system:
Good luck ... cheers, drl
Just for grins set the line kill character to @ and see what happens. Don't forget to reset it to what it was before. Older UNIX's had the line kill character set to @ and the classic text "The UNIX Programming Environment" mentions it too.
