Converting file names

The namespace of BS2000 files and PLAM library members is as a rule smaller than that of the client system. On the client system applications can therefore exist which cannot or can only with difficulty cope with the restrictions to the namespace which apply on the server. For example, editors create backup copies or buffer information under file names which are not permitted on the bs2fs file system on the server.

When files which have not yet been opened are deleted, NFS clients temporarily create files whose names consist of ".nfs" followed by varying numbers of hexadecimal digits. Consequently these file names are always converted as follows:

File name on the NFS client	File name in the bs2fs file system
.nfs[:xdigit:][:xdigit:]*	@nfs[:xdigit:][:xdigit:]*

When a bs2fs file system is shared, the bs2nameconv option of the share command can be used to specify that additional conversions should take place:

File name on the NFS client	File name in the bs2fs file system	Description of the file name on the NFS client and of the conversion rule
\.[^.].*	@[^.].*	File names containing at least two characters, the first character being a dot and the second character not a dot: the leading dot (.) is converted to an at character (@).
..*~.*	..*#.*	Filenames that contain the tilde except as the first  character: each tilde (~) is converted to a hash (#).
