command 2>&1 | less
you can redirect stderr (fd 2) with 2> file or 2>&1 (stderr goes to same
place as stdout) -- this is useful for a few things.. like redirecting ALL
output to a file.. like:
reallyverboseprogram > /dev/null 2>&1
note that this is not the same as 2>&1 > /dev/null -- as this redirect
stderr to the terminal.. then redirects stdout to /dev/null -- while err
is still going to terminal
hope that helps =)
