The pipe starts a process (using the command and parameters right of the pipe symbol) and sends the stdout of the "left" process to the stdin of the right process as in: ls -l | less ... this would send the output of "ls -l" to the input of "less", which pages that input for you, or ls -l | grep lolcat ...which sends the output of "ls -l" to the input of "grep lolcat", this last filtering out the lines containing the pattern "lolcat", while ">" would redirect the standard output to a file, like in ls -l > /tmp/result ...which will create a file /tmp/result (or replace an existing file) and fill it with "ls -l"'s output.
