Can I tee into a variable rather than file?
Is there a way i can tee into a variable rather than a file?
I want stdout and stderr to go to the screen as it is happening and capture a copy of it in a variable.

I can capture them w/
std_out_and_err=$($the_command 2>&1)
and then print $std_out_and_err.

But the command may be putting out output for a minute
or more and I really want it visible as it is happening.

I was hoping the tee command would do the trick but
I couldn't figure it out.
Thanks.

thanks. Creating a file's better than nothing, but does anyone know of a way to not have to create a file?
