perforce: list history of a file in main depot

Question

I want to find out the history of a file in main depot. In clearcase I can do with the following command

% ct lshist -r -branch main -since "01-Jan-2014" hello.cpp

What is the equivalent command in p4? I tried p4 filelog but wasn't able to come up with the right args.

Answer 1

p4 changes -l //depot/path/to/file

will display all changes to the file with the full description for each.
