Say a file is known to P4 as Foo.cpp
p4 files -e -m 100 //XXX/YYY/...foo.cpp*
(note the lower case f) can't find it. Has anyone overcome this issue?
EDIT: the place I am running the command from does not have a local p4 checkout so going through the file system is not an option here.
If you are able, I would highly recommend going through the trouble (thanks to Linux-dependency hell) of installing P4Search. It will give you the case-insensitive searching power you seek, but it will also save you hours and hours of time down the road.
