He appears to be searching through a text file, but my awk is not good enough to read the code.
I suggest he posts on www.unix.com in the Shell Scripting Forum top get an answer to this question.
The file he is searching through is the exported data from a table. When you export it to a file, it has all the statements inside of the file to re-create the table when "imported". (including the CREATE TABLE statement he has referenced.
My suggestion to him is, if he is going to seach a table for data, that he do it on the actual table in the database, instead of the back up file. Off hand, I don't remember the format of the backup file for the data portion.

Jeff
