gdb: Logging Output

 
 2.4 Logging Output
 ==================
 
 You may want to save the output of GDB commands to a file.  There are
 several commands to control GDB's logging.
 
 'set logging on'
      Enable logging.
 'set logging off'
      Disable logging.
 'set logging file FILE'
      Change the name of the current logfile.  The default logfile is
      'gdb.txt'.
 'set logging overwrite [on|off]'
      By default, GDB will append to the logfile.  Set 'overwrite' if you
      want 'set logging on' to overwrite the logfile instead.
 'set logging redirect [on|off]'
      By default, GDB output will go to both the terminal and the
      logfile.  Set 'redirect' if you want output to go only to the log
      file.
 'show logging'
      Show the current values of the logging settings.
