/usr/bin/updmerge [-r] directory
/usr/bin/updmerge file directory
-r Performs a recursive reinstallation of all the files and subdirectories
in the /var/adm/install/update area relative to the specified direc-
Specifies the directory from which the reinstallation is relative, typ-
ically the root (/) directory.
Specifies the name of a file in the update area, or specifies the rela-
tive pathname of that file from the update area.

The updmerge utility lets you merge files that have been preserved from a
previous installation into a new installation environment. Any user file or
customized file from a previous installation that you do not want replaced
or overwritten can be saved and reintegrated into a new installation
You must have superuser privileges to invoke the updmerge utility, and the
system must be in single-user mode. The updmerge utility must be invoked
from the /var/adm/install/update directory, which is created by the updmv
utility and contains entries for the files that have been preserved from
the previous installation.
+ Use the -r option followed by the directory operand to perform a
recursive installation of all preserved subdirectories under the
/var/adm/install/update area relative to a specific directory.
+ Use the directory operand only to install only those preserved files
directly under the /var/adm/install/update directory. This causes a
non-recursive merge of the files in the specified directory. If you
use the directory operand only, subdirectories in
/var/adm/install/update are not merged into the new installation
+ Use the file operand followed by the directory operand to install a
single preserved file. This file can be the name of the file in the
/var/adm/install/update directory, or it can contain the relative
pathname of that file from the /var/adm/install/update directory.
If the file operand is a directory name instead of a file name, the
updmerge utility reinstalls all files in that directory, but none in
To integrate files from the previous installation into the new installation
environment, the updmerge utility compares each preserved file to the newly
installed files with the following rules:
+ If the preserved file does not exist on the system, you can view the
preserved file before determining whether or not to install it.
+ If the preserved file does exist on the system, you can view the
differences between the preserved file and the newly installed file
before selecting the file you want installed on the system.
+ If a preserved file is identical to a newly installed file, a message
is issued and the next file is checked.
Recursively install all preserved subdirectories and files under
/var/adm/install/update relative to the root (/) directory:
updmerge -r /
Install the preserved /etc/hosts file relative to the root (/) directory:
updmerge etc/hosts /
Install the preserved files in the etc directory relative to the root (/)
directory (in this case, /etc):
updmerge etc /
