I am looking for a terminal command that not only list all of the installed applications but, also has a breif discription of each one
apt list --installed --verbose
To list installed packages and a brief description,
Run:
aptitude search '~i'
This displays nicely if you set your terminal size to 24 X 132
Did you look at the results of dpkg -l ?
It's results can be routed to a file if necessary/useful; though as you gave no OS & release details my quick test was on my release*
guiverc@d960-ubu2:/de2900/lubuntu_64$ dpkg -l >blah
guiverc@d960-ubu2:/de2900/lubuntu_64$ view blah

You can get a list of all commands on the system with man pages using
man -s 1,6,8 -k .
Section 1 is user commands, section 6 is games, section 8 is admin commands.
