Just so you are aware, we purposefully don't do homework here.
But, you're mostly okay. We will (if we know) nudge you in the right direction. We like to see previous attempts so that we can point out where you went wrong, which is all you're really lacking in your post.
Show us what you've got so far - and someone may chime in that can help.
Thanks and I totally get it about homeowrk! Here is what I have for exercise 1 so far:
ls -l /home/jdp/Desktop/sample/"abc xyz"
ls -l /home/jdp/Desktop/sample/abcde
ls -l /home/jdp/Desktop/sample/demofor
ls -l /home/jdp/Desktop/sample/demofor2
ls -l /home/jdp/Desktop/sample/demofor3
ls -l /home/jdp/scan1.sh
When I run it it gives me the atributes that show the date the file was created and the checksum for "abcde" and "demofor"
That's as far as I have gotten. Not sure where to proceed or even if what I have is correct. Any nudges would be appreciated
