This
    /usr/share/firefox_0.9.1/mozilla-xremote-client -a firefox "ping ()"
and
    REMOTE="/usr/lib/mozilla/mozilla-xremote-client -a firefox"
    $REMOTE "ping ()"
are identical.

Also, you don't need `...`

'pwd' usually don't take argument.  I don't think there is shell
wrapper for realpath(3).
