eliminating duplicate fields with corresponding records. 1

[billbose]

Hi experts,

I have a file containing duplicate fields(not records) like say, as follows:

1122 Mary
1122 Joe
1335 Reise
1324 John

After elminating the duplicate fields with the corresponding records, I should get a output like follows:

1122 Mary
1335 Reise
1324 John

Would somebody help me with a script?
TIA

Regards,
Bill

Thank you folks. However i sorted out the answer to the above problem. It is

awk '$1 != prev { print ; prev = $1}' < exatext3

Regards,

Bill
