Assuming you're in the top-level directory for the project within your
VOB...

for each in `grep -lR <pattern> .`; do 
cleartool checkout $each;
<sed command> $each;
cleartool checkin $each;
done

Alternatively, you could just hijack all the files and then run through
all the hijacked files and check them out, use the hijacked version as
the new version, and then check back in...
