Re: list of gcc files/purpose?

[sidster <patrick at boxsoft dot com>]

Greetings,

Try something like this:

#### Begin
CMDS="
  set width 0
  set height 0
  break main
  run $*
  while 1 
    step
  end
  quit
  "

# Note: no --batch
#
gdb --quiet $PROG<<EOT
$CMDS
EOT

#### End


That should work just fine :-)  (i think).



Enjoy,
