Dropping Records for unknown reason in awk script - Page 2

Franklin52 · #1 (**permalink**) 3 Weeks Ago

Assuming the length of a record is 77 you can do something like:

Code:

awk 'length < 77 {$0 = $0 "0000000000000000000000           NM X"}1' file > newfile

The result of the "cmp -l" looks like:

Code:

899  40  60
900  40  60
901  40  60

If you are missing records, it is most likely that the differences will not have a 40 (space) in the second field. Thus

Code:

cmp -l infile outfile |awk '$2 != 40' |head

would give the approximate locations of the missing records.
