Problem with NSFileManger directoryContentsAtPath
Hi All,
I'm facing an issue with NSFileManger directoryContentsAtPath API. This
seems to be an wried issue. But its very important for me to fix. Please
help me.
My application is trying to enumerate the folders in inside a Mac
using NSFileManager API. But for some files its failing.
It looks like the file name ( inside bundle ) is interpreted by Finder and
Terminal in a different ways. Can any one please suggest me a way to resolve
this issue.
Thanks in Advance

Re: Problem with NSFileManger directoryContentsAtPath
"Icon\r" is an invisible file that contains a custom directory icon.
What make you think this file is handle in different way ?
The terminal displays '\r' as ^M but it's not a problem. Isn't it?

Re: Problem with NSFileManger directoryContentsAtPath
This has to do with non-printable characters in pathnames. Each
application can different how they visually represent these
characters. The terminal just replaces them with '?', the Finder
might use a space.
When you have a path from NSFileManager, leave it as is in the
NSString if you're going to pass it to other Foundation file manager
APIs. If you need a C string of the path for C APIs, you can use
NSFileManager's fileSystemRepresentationWithPath: to get a properly
encoded C string. Also displayNameAtPath: can give you the proper
representation for displaying the path to the user but may not work
when passed to file system APIs.

Re: Problem with NSFileManger directoryContentsAtPath
When i perform ls command it shows file name as "Icon?". When i perform cp
command & tab it shows the file name as "Icon^M".
Why Terminal does show different names for the same file. When i see it in
Finder it does show as "Icon".
Please advise. Thanks in Advance.

Re: Problem with NSFileManger directoryContentsAtPath
Yes, they all display it in a different way, and why is it a problem ?
What does it prevent you to do?

Because the filename contains a non-printing character (http://en.wikipedia.org/wiki/Control_character). "bash" (which is what is performing the tab completion) and "ls" have different ways of denoting non-printing characters. NSLog is treating it as if there is an implicit line feed. > When i see it in > Finder it does show as "Icon". This would suggest that the Finder has been designed not to indicate the presence of non-printing characters. > Please advise. Thanks in Advance. Advise you about what, though?

Re: Problem with NSFileManger directoryContentsAtPath
When i give this filename as part of rsync source file ( using --files-from
) , rsync is treating this filename as 2 different file names , because
rsync expects each filen name separated by \r.
Hence my rsync command is failing

Maybe there's a different way to pass the filenames to rsync, or a way to specify a different delimiter.
