IMO, the smartctl attribute table is not poorly-formatted

The output format of the raw value may differ depending on type, value 
or drive database entry. This can be suppressed by '-v' option.

Examples:

Print temperature (last byte of raw value, remaining bytes may encode 
min/max)

$ smartctl -A -v N,raw8 /dev/ice | awk '$1==194 {print $15}'
31

Print attribute number/raw value pairs

$ smartctl -A -v N,raw48 /dev/ice | sed '1,/^ID#/d' | awk '{print $1,$10}'
1 0
3 7936
4 2266
5 0
7 0
8 11734
9 4539
10 0
11 0
12 1161
190 31
194 31
