Run the date command in such a way that the output from that command produces the current day, month, date, and year. Have that read into another command line, resulting in text that appears like the following (your date, of course, will be different): Today is Thursday, December 10, 2015.

~> echo "Today is $(date +'%A, %B %d, %Y')" >>tempFile.txt
~> cat tempFile.txt 
Today is Thursday, November 08, 2018 

Using variables, find out what your hostname, username, shell, and home directories are currently set to.

bash
~> echo $SHELL
/bin/bash
~> echo $HOSTNAME
wisamdev57
~> echo $USER
