e2fsck | tee causes "need terminal for interactive repairs" error

If I pipe the output of e2fsck to tee, to capture a copy of its
output, then e2fsck refuses to run interactively, because it wrongly
thinks that it isn't running on an interactive terminal. Does anyone
know a workaround for this problem?

I'm running it on Knoppix (Debian-based). Here's the output:

root@ttyp0[hdd9]# e2fsck -v /dev/hdd6 | tee -a hdd6log
e2fsck 1.35-WIP (21-Aug-2003)
e2fsck: need terminal for interactive repairs
root@ttyp0[hdd9]# uname -a
Linux Knoppix 2.4.22-xfs #1 SMP Fr Okt 3 20:36:25 CEST 2003 i686
GNU/Linux
root@ttyp0[hdd9]#

Thanks,
-Dave

Sorry, but it /rightly/ thinks that it isn't running on an interactive
terminal. To it, stdout is /not/ directed to a tty, and this means that
e2fsck /isn't/ being run interactively.

I don't /know/ of a workaround, but if one exists, I'd expect that it
involves PTYs or the use of ttysnoop

Take a look at http://ftp.debian.org/debian/pool/main/t/ttysnoop/

For a workaround, using the "script" command.

Depending on what you are doing, a simple solution may be to run
noninteractively (-p).
