Why does the noclobber variable not protect you from overwriting an existing file with cp or mv?
What will be an ideal response?
The noclobber variable implements a shell feature that keeps the shell from
overwriting a file; it does not work with utilities. Thus it keeps a redirect
symbol (>) from allowing the shell to overwrite a file (the shell redirects out-
put) but has no effect when you ask cp or mv to overwrite a file.
