Unix @ symbol does not work

Question

I'm using a HP-UX B.11.31 U and I needed to acess sqlplus but for some reason when I write a @ unix erases the line. So when I try to copy past user/pass@//host:port/SID I get //host:port/SID.

Answer 1

How about putting your argument into quotes 'user/pass@//host:port/SID'?
