peeking in on a pipe

[Root Boy Jim]

? I would like to 'peek' in on a pipe, to see what is happening in it, WHILE
? IT EXECUTES. I tried something like this, but no luck:
?  
?   some_stuff | tee `tty` | more_stuff
?  
? I would like to do this while it executes, not tee to a file and see it
? later. Does anyone have any ideas how this might be done?
? Thanks,
?  ...Tim

Yes. Simply use /dev/tty in place of "`tty`". Conceptually, it should
work, but R'ing TFM hints that only standard input is being checked.
To confirm this, try executing the following commands:

		echo `tty`
		echo `tty` < /dev/null

You will see "not a tty" on the latter.
