I think Thomas is concerned that although when you actually read a /sys
file, you know it's one string, that fact can get easily lost and cause issues
down the road. Consider this code:
foo=`cat /sys/some/file`
bar=`cat /sys/other/file`
baz=`cat /sys/third/file`
echo $foo $bar $baz | awk '{print $2 $3}'
Suddenly your output isn't what you expected...
