ITT 255 Command Directory Log Template
Overview:
The purpose of this document is to compile a list of the commands that you have learned and
used each week in the course. This command directory will assist you in completing activities, such as your final project, in later weeks of the course. Each week, you will submit this document updated with the new commands you have learned. Prompt:
It is recommended that you log every new command here when you learn it in your reading or labs/lessons. You should also log the date you learned the command and where in the learning resources you found it (so that you can find it again later).
Complete this template by filling in the blank cells in the table.
