Actually, that's what it should do.  When I was creating the program
somebody tested it by running it on a design with no components (just
IEC symbols, IIRC, and graphical elements).  Gattrib segfaulted upon
startup.  I checked into it further, and found that gattrib would 
segfault if you ran it on a non gschem .sch file.  (That is, if you
tried to open an arbitrary file.)  Therefore, I put a check in to
verify that components were found while reading the file, and if not,
then just tell the user & leave.

As to solving your problem, a Perl or Python script are your best
bets.  You could try sed, but my experience with sed is that the
syntax is so tortured that by the time I figure out what command to
issue, I could have already written and run the Perl script.  But I am
not a sed guru.  If you know its syntax and features, you'll be much
quicker at it than I.
