Hello monks,

I am having trouble with extracting text from unformatted descriptions. Basically, I need to extract disk capacity from the data center description which basically has a numeric value preceding the unit of measure like GB 

E.g. x='Disk - HD 500GB 2.5 SATA (00X3Y)'

I wrote a sed script 

echo $x | sed "s/^[^0-9]*\([0-9]*[.]*[0-9]*\)[^0-9A-Z]*GB.*/\1/g"

[download]


this works in this case. However, if I run into - x='USE 28-000009 FLASH CARD, IODUO, 1280GB, MLC, FUSION IO, FS3-204-641-CS-0001' 

echo $x | sed "s/^[^0-9]*\([0-9]*[.]*[0-9]*\)[^0-9A-Z]*GB.*/\1/g"

[download]


returns nothing

Any ideas?
