I have a document A, the format like:
buick|11-1-2008| FASDFDS
buick|11-1-2008|GTHRJUYR
buick|11-2-208|THYJJHGMHG
buick|11-3-208|TJLOUOYIG
.....
I want to turn it to document B:
buick|11-1-2008|2
buick|11-2-2008|1
buick|11-3-2008|1
basically to keep the 1st and 2nd column, while count the lines of the 3rd
column. A is sort and uniq.
if I only use "wc -l", it would only | s*********e
