How you use compare field 3 Location with field #6 to find missing location in ksh script? Thanks.

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:

#!/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.............
