find The find command takes a pattern as a command-line argument and recur- sively searches through directories to find a filename matching that pattern. It should print a relative path starting with "./" for every file/directory that matches. For example, running ./find 1s.c from within the hw2 directory should print ./1s.c. If run from the parent directory, the output would be . /hw2/1s.c. There may be multiple matches. If we run ./find .c from within the hw2 directory, we should see: ./find.c ./1s.c ./tree.c The output does not need to be sorted. If nothing matches, it shouldn't print anything. Pattern matching should be case sensitive.
