ussACTION can automatically and transparently
track, control, backup, and monitor changes or references to HFS and zFS files.
ussACTION delivers the same superior functionality as
eventACTION for Hierarchical File System (HFS) and zSeries File System (zFS)
files under the OS/390 and z/OS UNIX System Services (USS) system environment.
It looks similar to eventACTION, except that dataset and member are replaced by
directory and file name.
