Enter the CTRL-D or the :q command to exit from strdb.
Enter the CTRL-L command to refresh the screen.
Enter the :l command to start and stop logging to a file. strdb will log
commands and their output to a file. Enter the :l command specifying a file
name and the o option to open the log file and start logging. Then you can
enter strdb commands and see the output on the terminal. strdb saves a
record of the commands and output in the logging file. Once logging is
enabled, use CTRL-K to dump the current screen contents to the log file.
This allows the user to selectively log debug data and actions taken. You can
close the log file and stop logging by entering the :l command, the file name,
and the c option. An example is shown below.
:l strdb.log o
