That's because as soon as you do ":!echo" your shell's builtin "echo"
will be invoked rather
than vim's echo and your shell's echo hasn't got any idea what kind of
an argument: "line('.')"
is and freaks out.

Honggyu, my guess is that you are probably trying to do something that
you probably shouldn't
be trying to do and maybe advised to have a rethink.
IIRC, in vim there is:
:h 10_commandments

considerably worse than incest
or folk dancing."
HTH.
