OK. Thanks everybody for their input. Really appreciate all the answers. I
modified the first loop as follows to get the subshell to ignore HUP signal:


trap "" HUP; cat $log_file | {
    while read line
    do
        line_num=`expr $line_num + 1`
        echo $line_num: $line >> ./out.log
    done
}
