Re: No I/O redirection under GDB

I just found that gdb's "run" command doesn't action redirection (e.g. run
</dev/pty2 >/dev/pty2 2>&1, where the shell on /dev/pty2 is doing a long sleep).
Instead, the invoked program gets the redirections as command line arguments.

Looking through the archives, I found documenting this
behaviour. Chris Faylor commented at the time that fixing it was more trouble
than it appeared.

That was 15 years ago - has anything changed since? Anyone up for this or should
I have a go? I *could* simply make my target do the redirection itself, but that
doesn't help anyone else. OTOH if changing gdb really *is* that hard, maybe I
should just change my program anyway.

Any advice welcomed,

I think this is the intended design (see:
).  If you want *gdb's* input and output redirected, I would think you want to invoke
gdb with I/O redirection on the command line, as in:

gdb foo < infile > outfile
