Jack Wallen introduces you to a Linux command that can automatically execute a program repeatedly, so you can easily monitor the output for troubleshooting.

To use the command you would just type dir and press enter and you will see a listing of the current files in the directory you are in, including information about their file sizes, date and time ...

If you have a command that outputs a lot of data to the terminal, you might want to send that output to a file for easier (or later) viewing or sharing. Jack Wallen shows you how.
