[windows2000] Re: Appending logs to plain text-files

Chevrons are part of the input, output, piping system that Windows inherited
from DOS (and I suspect, DOS inherited from Unix - but I might be wrong).

The single right facing chevron (>) creates or overwrites output to a file
The double right facing chevron (>>) appends output to a file
The single left facing chevron (<) reads text from a file
The bar or pipe character (|) uses the output of one program as the input of
another

The numbers 1 and 2 are a fairly new addition, and I've definitely come
across these before in Linux, so when I saw 1>> instead of the >> I used on
one occasion, I tried adding 2>> and it worked... The only time I've seen
documentation about piping and redirection has been in DOS books...

Cool, thanks!

How come I've seen those chevron-documentations, I assume they are, aren't
they??
