Here are some interesting Linux terminal commands that you probably
didn't know about.
history
This command will give you a history of the last commands have been. On
my system it shows the last 2000 commands typed into the terminal.
history x
This will show the last x number of commands typed into the terminal.
history | grep command
With this command, you can search for something like 'ping', by using:
history | grep ping
history | awk 'BEGIN {FS="[ \t]+|\\|"} {print $3}' | sort | uniq -c | sort –n
This command will give you a sorted list of frequent commands with the number of times each one has been used.

There are also a bunch of fun programs that can be obtained through the different repositories. Here is a short list of ones that I've found:
sl
We can all admit to incorrectly typing the 'ls' command in the terminal.
It's reminiscent of our DOS days, and typing idr instead of dir. Well,
the 'sl' program will show an animated ascii steam train chugging across
the screen.
fortune
I think anyone who has ever used Linux knows about this one. Just type in ./fortune, in the terminal, and it will give you your fortune.
cowsay
Cowsay is another one that most people know about already. I like to combine fortune and cowsay with the 'fortune | cowsay' to get a fun fortune.

boxes (apt install boxes)
This is another fun one. It will take whatever text you give it, and put it into a text box from the terminal. Just use the pipe to redirect it, such
as: 'cat greeting.txt | boxes -d diamonds -a c'

figlet (apt install figlet)
This is one that's been around for awhile as well. It will take any text
you send it, and print it to the screen in a banner type font. Here's an example:
echo "Hello world" | figlet
_ _ _ _ _ _
| | | | ___| | | ___ __ _____ _ __| | __| |
| |_ |/ _ \ | |/ _ \ \ \ /\ / / _ \| '__| |/ _` |

|_ |_\___|__|\___/ \_/\_/ \___/|_ |_\__,_|
cmatrix (apt install cmatrix)
This one will turn your computer monitor into one of the monitors from the movie Matrix. You will see the green letters falling from the top. There
are even options to change the color, speed, etc. This can even be set up
as you screensaver.
The last one I'll tell you about, was probably very popluar back when movies such as Mission Impossible first came out. This one will make your screen
look as though you are a Hollywood hacker. One word of caution with this
one. Turn your speakers down. There is delayed audio that is very loud!
This one is called hollywood. (apt install hollywood)
