The following shell will check for the first field and append the second field values to a single record if the first field value is common, say it will be like,
Code:
0504400323702|Pro Plan 7-8 lb Cat Fd+ 11 of 10 03/14/13~Pro Plan 3.5-4lb Cat Fo 1 of 10 04/02/12~|
Now the requirement is, if we have more than two records for the same first field, we should only append the second filed of these first two records, others has to be omitted,
Please let me know what modifications need to be done in below script
Code:
