How to grep on gdb print

Is there a way to grep on the output of print command in gdb? In my case, I am debugging a core dump using gdb and the object I am debugging contains hell lots of elements.

I am finding it difficult to look for a matching attribute i.e:

(gdb) print *this | grep <attribute>
Solution

  • (gdb) print *this | grep

    The "standard" way to achieve this is to use Meta-X gdb in emacs.

    An alternative:

    (gdb) set logging on
(gdb) print *this
(gdb) set logging off
(gdb) shell grep attribute gdb.txt

    The patch mentioned by cnicutar sure looks attractive compared to the above. I am guessing the reason it (or its equivalent) was never submitted is that most GDB maintainers use emacs, and so don't have this problem in the first place.
