On my application there are lots of users are doing there work or tasks? ...In my SSH or in 'Putty' i am observing logs?
Hot to observe one particular 'user' logs.. even through there are lots of users working on it?

For EX: i am log in with use rid:nikhil@in.com. another one log in with john@in.com another one with another uid,pwd... etc i am doing my business on it like that another one doing their business? But under logs the contents is comming continuosly like mixed with all other users .... here i want to see only contents of login with my useid here it is nikhil@in.com.

my commands for seeing logs are here : tail -f logs/application.log

logs is dir
application.log is logs file.

it would be appreciated if any one help in this regard..
