set radix 0xa
sets the base to decimal. On the other hand, set
radix 10 leaves the radix unchanged no matter
what it was.
set output-radix base
Set the default base for numeric display. Supported
choices for base are decimal 8, 10, or 16. base must
itself be specified either unambiguously or using the
current default radix.
show input-radix Display the current default base for numeric input.
show output-radix Display the current default base for numeric display.
17.6 Optional warnings and messages
By default, GDB is silent about its inner workings. If you are running on a slow machine,
you may want to use the set verbose command. This makes GDB tell you when it
does a lengthy internal operation, so you will not think it has crashed.
Currently, the messages controlled by set verbose are those which announce that the
symbol table for a source file is being read; see symbol-file in “Commands to specify
files” (page 125).
set verbose on Enables GDB output of certain informational messages.
set verbose off Disables GDB output of certain informational messages.
show verbose Displays whether set verbose is on or o.
By default, if GDB encounters bugs in the symbol table of an object file, it is silent; but
if you are debugging a compiler, you may nd this information useful (see “Specifying
shared library locations” (page 130)).
set complaints limit Permits GDB to output limit complaints about each
type of unusual symbols before becoming silent about
the problem. Set limit to zero to suppress all
complaints; set it to a large number to prevent
complaints from being suppressed.
show complaints Displays how many symbol complaints GDB is
permitted to produce.
By default, GDB is cautious, and asks the user to confirm on certain commands. For
example, if you try to run a program which is already running:
((gdb)) run
The program being debugged has been started already.
Start it from the beginning? (y or n)
If you are willing to unflinchingly face the consequences of your own commands, you
can disable this feature:
set confirm off Disables confirmation requests.
