As far as I know, we can make files over 4GB with XFS file system.
Files can be created in Bash ( can create XFS, EXT3 )
However, in csh, the files exceeding 4GB does not get created. It only
created smaller size. ( Can not create XFS, EXT3)
I would like to know whether you need setting like Kernel, or if the
files are not created because of the characteristic of csh.
