Hello,

Need assistance to redirect stderr to a file and display simutaneously.

Thanks.

It would be easier to redirect stderr to a file then if you desire, use more on that file:
$ command 2> file &
$ more file

Otherwise you would have to use tee(1) and that would have issues with what you want to do with stdout.

Hi:

If you wish to only have STDERR recorded in a file, but *both* STDERR and STDOUT written to your terminal simultaneously, you could do:

# ./myprocess 2>&1 1>/dev/tty|tee ./mylog

...where, for example:

# cat ./myprocess
#!/usr/bin/sh
while true
do
print -u2 "STDERR"
echo "STDOUT"
sleep 1
done

Regards!
