Copy files and change case - any ready made utliities around?
I want to keep two directories in sync but with a slight difference, I want the 'destination' directory to have lower case names only. I.e. any file in the source directory that has an upper case name (or any upper case characters in its name) I want copied to the destination directory with a lower case name. I guess I can come up with solutions that need me to write a wrapper script of some sort for rsync but I was wondering if anyone has any ideas for a ready made solution. This needs to be run as a cron job by the way. -- Chris Green

And there'll never be a name clash with just a difference in case?

No, these are photo image files with formats like DSCF1234.JPG, I just happen to want a mirror directory of the same files with lower case names. If there's a file DSCF1234.JPG and a dscf1234.jpg then they're almost certainly the same file. The source/parent directory will always have the originals anyway. -- Chris Green

Can't you do this with rename ? rename 'y/A-Z/a-z/' * nev

Yes, but that stops rsync working. I want to synchronize a directory full of files with uppercase/mixed names with a directory having the same files with all lowercase names. -- Chris Green

I'm not sure I have quite understood the use case but have you looked at ciopfs? http://www.brain-dump.org/projects/ciopfs/ This is a FUSE-based file system that maps mixed case files to lower case and allows access to files on the filesystem in a case-insensitive way. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

That might well do what I want, thanks for the pointer. -- Chris Green

I was composing a serious reply where I was writing that you should edit receiver.c in rsync (because, this kind of change should belong there, together with a command line option), but I fell off my chair in disgust at the sloppy code that comprises rsync. I think you should give Mark's FUSE solution a go... it beats having to spend hours fixing up rsync [receive_data() or recv_files(), but probably the former, doing a tolower() on fname.... d'oh it's actually line 691, function recv_files() as I was originally writing, where fd2 is opened]. Good luck. Srdjan
