You can use the uniq keyword in Linux.
Ex:
Assuming you have a text file test.txt that contains a pipe delimited bunch of data you can use the below command.
cut -f5 -d'|' test.txt | sort | uniq -d
Here 5 is the column which you want to check dupes.
The output of the command would be all the duplicate entries in that column.
