Answer:
Name of Operating System: Ubuntu
Five legal file names:
inventory.txt
total.txt
NIKKAH.txt
Defaulter.txt
studenT.txt
Five illegal file names:
wel/come.txt
..
MY>note.txt
.
my<work.yxt
Explanation:
To fix the illegal name:
1. Remove the special character, so it becomes welcome.txt
2. Remove the double dot and rename using text characters
3. Remove the special character, so it becomes MYnote.txt
4. A file cannot be named using dot. So we rename to a textual name
5. Remove the special character, so it becomes mywork.txt
Some additional rule for naming of files legally in Unix is that, you cannot use a reserved word to name your file. Starting a file name with number is allowed. Starting a file name with dot make the file to be hidden.
