(gdb) help source
Read commands from a file named FILE.
Optional -v switch (before the filename) causes each command in
FILE to be echoed as it is executed.
Note that the file ".gdbinit" is read automatically in this way
when GDB is started.
Optional -p switch (before the filename) causes FILE to be evaluated
as Python code.

(gdb) set breakpoint pending on
(gdb) help set breakpoint pending 
Set debugger's behavior regarding pending breakpoints.
If on, an unrecognized breakpoint location will cause gdb to create a
pending breakpoint.  If off, an unrecognized breakpoint location results in
an error.  If auto, an unrecognized breakpoint location results in a
user-query to see if a pending breakpoint should be created.

In some other cases one needs:

(gdb) set confirm off 
(gdb) help set confirm 
Set whether to confirm potentially dangerous operations.
