Filter out columns with same value from a list

[TSch]

Hello again,

I'm facing the following Problem (AIX, ksh):

I got a list containing the following columns:

Filename;OrderNo;ModifyDateofFile

Now the challenge is to filter out all the entries with the same OrderNo and only keep the one with the latest ModifyDateofFile Timestamp ...

Any ideas how I can do this ?

Regards,
Thomas

Use sort and then uniq commands.
