usync

usync(8)						      System Manager's Manual							  usync(8)

NAME

       usync - synchronize two setld inventory files to reflect current system status

SYNOPSIS

       /usr/lbin/usync [-d] file1 file2

OPTIONS

       Enables debugging.  This will print the pairs of pathnames being synchronized on the standard output.

DESCRIPTION

       The usync command is used to achieve inventory synchronization by merging two inventory files according to the pathname field of the inven-
       tory records.  The result is directed to standard output.

       If the two inventory files contain records with the same pathname, the record in file2 is written and the record in file1 is  ignored.	If
       either inventory file contains a pathname not present in the other file, the record containing that pathname is written to standard output.
       To reflect the current system inventory, file2 should represent a later installation than file1.

RESTRICTIONS

       The two inventory files must be sorted in ascending ASCII sequence on the pathname field.

ERRORS

       usync: file is corrupt

   Explanation:
       Records in one of the inventory files are not sorted properly.

EXAMPLES

       The following command produces a synchronized inventory for two versions of the OATDCB subset: /usr/lbin/usync OATDCB100.inv OATDCB120.inv

FILES

       Subset inventory files
