In vim create the file uon.sh. For the second and third comment lines insert your name and date. The lines that contain #... are comments to the program, Replace the ??? with your comments explaining what happens in that line of the program. Submit the program with your name using the following command:

wmorales@syccuxfs01:~> cat uon.sh

#!/bin/bash # Your Name # Date #uon.sh: this program will ???????? until who | grep "$1" > /dev/null #?????????? do sleep 30 #?????????? done echo "$1 is logged on." exit 0

After replacing the question marks with your explanation, test it. Make a copy named uon.sh.txt, convert it to DOS format using the command unix2dos, transfer it to your computer using psftp or filezilla.
