use this

I assumed from the authors description that the first field remains common in the file

Quote:
START
ABC|Prashant1|Patel1
ABC|Prashant2|Patel2
ABC|Prashant1|Patel1
ABC|Prashant2|Patel2
END
...

3) Remove ABC|
Use this if you didnt mean that the first field woudl be same.
Code:
grep "|" test | cut -d'|' -f2,3 | sort -u

or with slight amendment to code written by zenith i.e. by adding OFS
