  I missed that feature...  It sure does.  Does it have a way to add
context lines (like grep -C)?  That is a nice feature of qsubst.  I can't
tell from a single line all the time if I need to replace.  Also, it looks
like cscope doesn't offer a regular expression find and replace like

$ perl -i -p -e 's/from/to/g' *.c *.h

would do.  Neither does qsubst, so I'm not totally satisfied yet.

I think you meant:

$ find . -name "*.c" | xargs cscope

(unless cscope takes files on stdin)
