bos uninstall

Purpose

Reverts to the former version of a process's binary file

Synopsis

bos uninstall -server <machine name>  -file <files to uninstall>⁺ 
              [-dir <destination dir>]  [-cell <cell name>]  
              [-noauth]  [-localauth]  [-help]
   
bos u -s <machine name>  -f <files to uninstall>⁺  [-d <destination dir>] 
      [-c <cell name>]  [-n]  [-l]  [-h]

Description

The bos uninstall command replaces each binary file specified by the -file argument with its .BAKversion on the server machine named by the -server argument, which is normally the binary distribution machine for its CPU/operating system type. It also changes the extension on the current .OLD version (if any) to .BAK. Each binary file must reside in the local /usr/afs/bin directory unless the -dir argument names an alternate directory.

To start using the reverted binary immediately, issue the bos restart command. Otherwise, the BOS Server automatically restarts the process at the time defined in the /usr/afs/local/BosConfig file; use the bos getrestart command to display the time and the bos setrestart time to set it.

Options

-server

Indicates the binary distribution machine on which to revert to the .BAK version of binaries. Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see the introductory reference page for the bos command suite.

If the machine is not a binary distribution machine and is running an upclientbin process, then the files are overwritten the next time the upclientbin process fetches the corresponding file from the distribution machine (by default within five minutes).

-file

Names each binary file to replace with its .BAK version.

-dir

Provides the complete pathname of the local disk directory containing each file named by the -file argument. It is necessary only if the binaries are not in the /usr/afs/bin directory.

-cell

Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see the introductory bos reference page.

-noauth

Assigns the unprivileged identity anonymous to the issuer. Do not combine this flag with the -localauth flag. For more details, see the introductory bos reference page.

-localauth

Constructs a server ticket using a key from the local /usr/afs/etc/KeyFile file. The bos command interpreter presents the ticket to the BOS Server during mutual authentication. Do not combine this flag with the -cell or -noauth options. For more details, see the introductory bos reference page.

-help

Prints the online help for this command. All other valid options are ignored.

Examples

The following example command overwrites the /usr/afs/bin/kaserver file on the machine fs4.abc.com with its .BAKversion, and the current .BAK version by the .OLDversion.

   % bos uninstall -server fs4.abc.com -file kaserver

Privilege Required

The issuer must be listed in the /usr/afs/etc/UserList file on the machine named by the -server argument, or must be logged onto a server machine as the local superuser root if the -localauth flag is included.
