pipeling help
 

Hi i know how re redirect the ouput of the command... can u plz reming me what 2> and 1> mean?
Are there any other types of pipes?

First, redirection and pipes are two different things. Redirection relates to stdout, stdin, and stderr.
Pipes are for sending output of command A to the input of command B.

File descriptors are:
0 stdin
1 stdout
2 stderr

So "1>xxx" means send output to xxx instead of stdout
