A path indicating the directory to change into.
The cd command operates within a SILO data file in the same manner that the UNIX TM cd command operates within the UNIX TM file system. By default, the active directory is the root directory, indicated by a slash " / ". By using the ls and cd commands, one can navigate through a SILO file. The cd command understands both absolute and relative pathnames, hence the path " .. " means move up one directory level. Without an argument, cd changes back to the root directory.
Note that this command works on SILO files, not UNIX TM files. This means that the " ~ " operator in a path will not work.
