Flag duplicate enteries

Morning Unix Guru's,
I have written a script which output the contents of a DB. No the DB is not clever to check this or flag and there is no command for the tool to flag this, which human intervention.

But i need to check to see if there are duplicate enteries in the file output and flag them.

So the example below there is duplicate enteries for actlni02 and allocd01.

How do i flag this?


Code:
actlni02              LDN_CAM_UX_PRD
actlni02              LDN_DKTP_PC
actlnp03             LDN_CAM_UX_PRD
adsdbi01             LDN_CAM_UX_PRD
algomd01            LDN_WAT_UX_DEV
allocd01              LDN_CAM_UX_DEV
allocd01              LDN_WAT_UX_DEV

Any advice will be greatly appericated.
