> $ echo Hello World > peanuts.txt

">" - use the input stream and return the output somewhere
">>" - redirection operator that only appends files

## Input stream
"<" - redirection operator that changes the input stream

Example:
$ cat < peanuts.txt > banana.txt

In this case, peanuts.txt is the input stream.

"2>" - basically a stdout redirection operator but for errors

Example:
$ ls /fake/directory 2> peanuts.txt
