[aprssig] sorting aprs data (sort / uniq

I want to sort some aprs data and count traffic.

Can anyone confirm this is the case ?

1) 'sort' sort the file alphabetically
2) 'uniq' returns occurances but they must be next to each other in the
3) 'sort data | uniq' sorts the data that uniq needs to single out
4) 'sort data | uniq -c' sorts and returns counts of unique occurances
5) 'sort data | uniq -c | sort -n' returns unique occurances and counts,
counts sorted smallest to largest 

I basically found data needs to be fed to uniq
