Problem
1. Look up the man pages of mkdir to find out the easiest way of creating this directory structure: share/man/cat1.
2. If mkdir test fails, what could be the possible reasons?
3. How do you run ls to
(i) mark directories and executables separately,
(ii) also display hidden files?
4. What will cat foo foo foo display?
5. A file contains nonprintable characters. How do you view them?
