in thread what does "$@" mean?

The Perl special variable  $@ holds the reason why  eval failed during compilation or execution. See the discussion of eval in perlfunc. Perl failures may have causes that do not originate in eval, and the reasons (actually, error message strings or numeric codes) for these failures are held in other error variables.
