get particular value from the given line using shell script

nagendrar · 11-10-2011, 06:13 AM

I have following two lines

Model: WDC WD400BB-75C Revision: Serial No: WD-WMA8H3231261 Size: 40.00GB <39999504384 bytes>

Vendor: Lite-On Product: LTN486 48x Max Revision: YD01 Serial No:1234

please help me to get values (Ex: WD-WMA8H3231261,1234) of "Serial No" only using shell script?

or

Please help me to cut until "Serial No" and get the remaining.

ThanQ,
Nagendra

Code:

sed 's/.*Serial No: \?\([A-Z0-9\-]*\).*/\1/' filename

Or, add a clause to get rid of the empty lines, too:

Code:

sed -e 's/.*Serial No: \?\([A-Z0-9\-]*\).*/\1/' -e '/^[ \t]*$/d' filename

outputs:
WD-WMA8H3231261
1234

If "Serial No: <serial number>" is always followed by space or line end this pure bash solution

Code:

while read -r line
do
    buf=${line#*Serial No: }
    echo $(buf% *}
done < input.txt

Code:

awk '/Serial No/{getline;print}' RS=" *: *" file
