Representation of files in the bs2fs file system

How BS2000 files are represented in a bs2fs file system depends on whether "simple" DMS files or PLAM libraries are concerned:

• DMS files are represented as files in POSIX.

• PLAM libraries are represented as directories with a permanently predefined two-level hierarchy in POSIX.

The names of these files and directories are identical to the names of the corresponding DMS files, library elements or PLAM libraries. However, in BS2000 the file names are not case-sensitive.

The following applies for the notation for file names in the bs2fs file system:

• File names are always output in lowercase notation.

• Entry can generally take place in uppercase or lowercase notation or a mixture of both. When wildcards are used in the shell or in the case of the find command, however, only lowercase notation may be employed, otherwise no corresponding file names are
  found.

• As customary in the POSIX shell, special characters of the POSIX shell (e.g. '$' or '*') must be explicitly escaped during input.

  Examples of how to escape BS2000 file name BS2DAT$$1:

  ls /home/bach/bs2fs1/bs2dat\$\$1

  ls /home/bach/bs2fs1/'bs2dat$$1'
