Hi,
In the same gdb session, I can use up or down arrow to recall commands.
But once a gdb session is start over, all the history commands are
gone. I'm wondering if it is possible to recall those commands?
Thanks,
Peng

Take a look at the section on saving history in the GDB manual.
Someone else asked me about this last week. I've been thinking about
adjusting it to use ~/.gdb_history instead of ./.gdb_history by default
and then enabling it by default. After all, everyone seems to assume
their shell will save CLI history, why shouldn't we?

I agree with turning history saving on by default, but why change the
location of .gdb_history? That'd be an incompatible change, and I
don't see the justification for such a change. Do you?

I think that making GDB start to write temporary files in $PWD by
default would be extremely annoying. I'd end up with dozens of them
littered around my source directories and other places where they
aren't wanted (and probably get lots of bug reports from confused
Debian users about it). By analogy with bash, I figured $HOME would
be the right default location for history.

Okay, but can we at least make it read ./.gdb_history, if that exists?

I can see why that would be a good idea. Before I make any changes in
this area, I will definitely look into that and see if it's possible.
Or a simpler possibility: we could use .gdb_history as the default if
it exists and $HOME/.gdb_history otherwise.
