Need Unix Help - please

Question

I need help with Unix commands -

Provide the full Unix command, using I/O redirection, that stores the contents of file A into a new file called D.

Provide another Unix command that stores the contents of file A into a new file called E, using a pipe.

Thanks

Answer 1

In the spirit of teaching a man to fish, I recommend that you look into borrowing or purchasing a copy of The Unix Programming Environment or a similar book.

Answer 2

cat A > D
cat A | cat > D # Does this count? It does use a pipe.

Also take a look at man bash and man cat
