The below example will load each field into a separate variable(i.e. f1 thru f7) and you can then compare them or do whatever you want with them:
Code:
#!/bin/ksh
# Process records in data file(A.txt)
file_rec_count=0
while IFS="|" read f1 f2 f3 f4 f5 f6 f7
do
  (( file_rec_count+=1 ))
  ### Variables loaded from each data record, fields are delimited by a pipe symbol( i.e. '|')
  # f1               field1
  # f2               field2
  # f3               field3
  # f4               field4
  # f5               field5
  # f6               field6
  # f7               field7
 ............Your code to comapre fields or whatever you want to do with them.............

deleting records with a missing field

I had to delete rows when a record was missing a field. My solution was cut -c 202-402 ${dataFile} | awk '{if (substr($0,103,30) !~ /^ *$/) print $0} >> ${workFile} The cut is because they came two records to a row. Anyone want to offer a more elegant solution? (2 Replies)
