My suggestion is using exec commoand to change output.
set_output () {
if "$QUIET" ; then
exec 3>&1 4>&2 >> /home/steven/mfgbacker/serr 2>&1
fi
}
reset_output () {
if "$QUIET" ; then
exec 1>&3 2>&4 3>&- 4>&-
fi
}
if [ "$1" = "quiet" ]; then
QUIET=/bin/true
else
QUIET=/bin/false
fi
(snip)
set_output
mkisofs -R -J -q -o /back1/tarback/dvd.iso /back1/tarback/*.tgz
reset_output
