need to remove duplicates based on key in first column and pattern in last column
Given a file such as this I need to remove the duplicates.
The key is the first column.
The last column determines which record to keep, that is delete all other duplicates and only keep that one. The last column with the greatest date and time should be kept as shown in bold.
