-break-commands @var{number} [ @var{command1} ... @var{commandN} ]

@end smallexample

|
||||
Specifies the CLI commands that should be executed when breakpoint
|
||||
@var{number} is hit. The parameters @var{command1} to @var{commandN}
|
||||
are the commands. If no command is specified, any previously-set
|
||||
commands are cleared. @xref{Break Commands}. Typical use of this
|
||||
functionality is tracing a program, that is, printing of values of
|
||||
some variables whenever breakpoint is hit and then continuing.
|
||||
|
