HP MPE/iX 6.x Operating System 175

NEWLINK

Operation Notes

You can use the NEWLINK command to create a link to a le, group, accoun t, or directory. You can issue the NEWLINK command from a session, job, program, or in BREAK. NEWLINK requires Save Files (SF) capabilit y, Create Directory entry (CD) and Traverse Directory (TD) permissions.

When newlink represents a path to a sym bolic link, the target of that sym bolic link is used as the name of the new link that is being created.

The NEWLINK command fails if the path represen ted by linkname points to a le or directory that already exists.

The following table lists all the CI commands that operate on les, groups, accounts, or directories and are aected b y symbolic linking. Keep in mind the following data poin ts when using the table belo w:

Typically, a symbolic link always resolves to its target name.

The Follow Link column applies to the lename portion (last componen t) of an HFS path.
