command to get application name

If typing lsof -i :80 ,

I get the name as *:http (LISTEN) and some othr like this. what command is to get the exact application name like mozzilla firefox or lotus notes or like that

I suppose its OS and version dependant...
I get with your exact command, the command in first column (on AIX6.1)...

I am able to get application name in command prompt using netstat but not able to get in linux.

I am getting firefox.exe, nlnotes.exe and putty.exe in command prompt
