How can I define the breakpoint-commands in my gdbinit file

How can I define the breakpoint-commands in my gdbinit file

[Luo Yi]

How can I define the breakpoint-commands in my gdbinit file ?

define b1
b *0x805d3bf
commands
silent
printf "ne, eax = %x\n", $eax
end    <<< ------------
end

the commands need a end instruction which can't appear in the middle
of the gdbinit file.

It should work fine.  Are you using the latest GDB?

Then I was wrong - it must be broken.

There are bugs in nesting canned commands that are finished by `end'.

I have a local patch to solve at least some of the bugs, but I never
got to apply it because I was requested to show the results of the
test suite after applying the patch, and never had time to install
expect and run the suite.

I could try to dig out that patch, if you want to try it.

I already did, almost a year ago:
