To open SQL Profiler (right now I am talking about SQL Server 2012) you need to write Profiler.exe on run command as shown in below figure
for earlier version you can use profiler90.exe.
You can find various parameters option using Profiler.exe –? command
When you run this command you will find below screen.
Although It does not impact how you open profiler but it is good to know thing 
Enjoy !!!
