Exactly, thanks for sharing. I've added some comments below for some
common gotchas that always get me with bash scripts. Hope it's helpful.

It might be a bit more error-proof to use, since the file argument could
be in the current directory (no '/'):
test -f %{arg} && file="-f" || file=""
> pkg=$(rpm -q $file --qf '%{sourcerpm}\n' $arg|head -1)
If conditionally initializing the value of $file, you might want to
provide a default value above. Perhaps something like the following to
default to the empty '' string if no value is set. If you use the
earlier statement, it will be initialized.
${file:-}

Nice, I didn't realize that a single '%' would do the *shortest* match.
Thanks!

Yeah, exactly. As an extra data point, dmalcolm posted a somewhat
script that opens up a bugzilla web page to assist in filing a bug
against a component. I'm sure that could be adjusted to find the
%{sourcerpm} name using the procedure you outlined.
