The $() construct is command substitution. You often see it as
a pair of backticks ``.
In your case, the "tar c" command is followed by the output from the find
command.

You could do this in at least two ways:
$( find / -name /*.conf | grep -v "*.so.conf" )
$( find / -name /*.conf -not -name *.so.conf)
The former ignores any line endingin in .so.conf; the latter uses native
find functionality.
