Create a pipe that writes to multiple files (tee)

Question

I would like to create a pipe in a ksh script (using exec) that pipe\'s to a tee, and sends the output to a pipe.

Current:

#Redirect EVE         


        

Answer 1

Instead of:

exec 1>tee -a ${Log} >&3

do simply:

tee -a ${Log} >&3 &

tee will fork into the background, and will consume the calling process' (i.e. your script's) STDIN as it was at the time that tee forked.
