updadmin - Invokes the Update Installation Cleanup utility
to remove or archive backup files created by an Update
The updadmin command invokes the Update Administration
Cleanup utility, which removes or archives the backup
files that were created by an Update Installation process.
There are no flags or options associated with this
command. Running this utility is an optional step after
performing an Update Installation, but it is recommended
if you want to recover disk space being consumed by these
The backup files that are created by an Update Installation
have these extensions: *.PreMRG - A file saved to a
extension is a backup copy of a customized protected system
file. System files in this category are system files
that are expected to be customized by users, for example,
/etc/passwd and /etc/hosts. If the automatic merge process
fails to merge the new version of the file with your customizations
to the file, your customizations must be
merged manually into the new version of the file when the
Update Installation is complete. The *.PreMRG version is
a copy of the file as it existed before the Update Installation
and only will be present if the automatic merge
fails. *.PreUPD - A file saved to a extension is a backup
copy of a customized unprotected system file as it existed
before the Update Installation. System files in this category
are system files that are not expected to be customized
by users, for example, /usr/bin/X11/netscape. If
an unprotected system file is altered in any way, customizations
must be merged manually into the new version
of the system file when the Update Installation is complete.
When you are finished merging your customizations into the
new version of the file, these backup files no longer are
needed, and they can be removed or archived.
The Update Installation Cleanup utility gives you the
option to archive or remove all backup files, or to select
only the files you want. You are prompted to enter an
archive destination if you decide to archive the files.
The Update Installation Cleanup utility uses the tar(1)
command to create the archive, and the archive destination
can be any archive destination supported by the tar command,
including tape devices. The default archive location
is the backup.tar file in the /var/adm/update/ directory.
You can use any file name you want, but if you want the
file to have a extension, you must enter it as part of the
file name. If the file name exists, it is overwritten. You
have the option to compress the archive file with the gzip
utility; if you do, a extension is appended automatically.
Unless you compress the archive file, the space savings
realized by archiving to a tar file on disk will be only
in moving the files from the / (root), /usr, or /var file
systems to the file system containing the archive. To save
disk space, archive the files to tape.
To archive to a tape device in tar format, enter archive
destinations similar to the following: /dev/tape/tape0c -
archives to a default density rewind tape (with compression)
/dev/ntape/tape0_d0 - archives to a nonrewind tape
device 0. The _d0 suffix specifies the density. If you
are archiving to a nonrewind tape device, it is recommended
to use a brand new or erasable tape.
On systems capable of graphical display, the updadmin command
invokes a graphical user interface to the Update
Installation Cleanup utility. On systems that are not
capable of graphical displays, a text-based, menu-driven
user interface is invoked. The Update Installation Cleanup
utility is also available as a task from the SysMan Menu.
To view the online help for the Update Installation
Cleanup utility without running the utility, use the following
command: # /usr/dt/bin/dthelpview -h /usr/dt/appconfig/help/C/updadmin.sdl
You must have root privileges to use the Update Installation
If your system has not been updated to the next version of
the operating system by the Update Installation process,
the Update Installation Cleanup utility cannot be invoked.
