I can't tell what you're trying to do from this incomplete example, but it looks like you're expecting the 2>&1 to do something other than what it's actually doing. It's only pointing the second tee's stderr to wherever its stdout was going. If the above pipeline is run in isolation from an interactive shell prompt, the 2>&1 is accomplishing nothing at all, since stderr and stdout will already be going to the same place (the tty) anyway. tee's stderr will normally be empty; it would only print an error message there if it had trouble writing to somescript.log. Post a more complete description of your intent. -- Alan Curry
