### 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.
