rename command fails on OSX

trying to change a file extension from ".f90" to ".F90". tried using quotes but that fails, too. what am i missing? /Users/mark/mmf/SPCAM/trunk/models/atm/cam/src/physics/crm> svn move abcoefs.f90 abcoefs.F90 svn: Path 'abcoefs.F90' is not a directory /Users/mark/mmf/SPCAM/trunk/models/atm/ca

new repo organization and merging advice needed

ate repos for AAA, BBB and CCC or just set them up as three separate projects within the same repo? Thanks! Mark Branson
