tar exit status
I am using tar to backup files to tape.

When the tape is full, I'm prompted for a second tape and told to press enter when ready. When I press enter, tar stops and gives an exit status of 5. Does anyone know what this indicates?

Also, if everything fits on one tape and the backup completes, I am getting an exit status of 1 (should be 0 if completed sucessfully). Any idea why?

This is the command I use (executed from a unix script) :

tar cvf /dev/rmt/1m `cat filelist`

(the filelist just contains \ so that everying from root down is backed up).

updadmin

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

NAME

       updadmin - Invokes the Update Installation Cleanup utility to remove or archive backup files created by an Update Installation

SYNOPSIS

       /usr/sbin/updadmin

DESCRIPTION

       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 backup files.

       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  Installa-
       tion.  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 des-
       tination 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  util-
       ity.  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

RESTRICTIONS

       You must have root privileges to use the Update Installation Cleanup utility.

       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.
