Extract value from file

I have a file where data is pipe seperated. I want to extract a field which is 12 characters in length and starts with BBG(|BBG000KFWBB1|). Both has pipe delimeter at the start and end. The value can be anywhere in the file.

I want to extract this field that starts with BBG from the file(inputfile.out). File has 70k or more rows. My output should be BBG000KFWBB1.

perl -ne 'print "$1\n" if(/.*?\|(.*)\|.*/)' inputfile.out

Not sure what you want, can you post more real data?
awk 'a=match($0,/\|............\|/) {print substr($0,a+1,12)}'

Then this should do it
awk 'a=match($0,/\|BBG.........\|/) {print substr($0,a+1,12)}' file

Does your file have other types of filed, other with of field?
awk -F\| '{print $2}' file

If you look at your AWK man page or search for AWK tutorials online, you'll quickly find the answer to you $0 question.

/ is a regular expression delimiter and \ is used to escape the character that follows it. If you are not familiar with regular expressions, you need to set aside some time for study.
