# bos\_uninstall(8)

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

## NAME

bos\_uninstall - 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 `".BAK"` version 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/lib/openafs* 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 */etc/openafs/BosConfig* file; use the **bos** **getrestart** command to display the time and the **bos setrestart** time to set it.

## OPTIONS

- **-server** \<*machine name*\>

  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 [**bos**(8)](/bos/8.md).

  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** \<*files to uninstall*\>+

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

- **-dir** \<*destinatino 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/lib/openafs* directory.

- **-cell** \<*cell name*\>

  Names the cell in which to run the command. Do not combine this argument with the **-localauth** flag. For more details, see [**bos**(8)](/bos/8.md).

- **-noauth**

  Assigns the unprivileged identity `"anonymous"` to the issuer. Do not combine this flag with the **-localauth** flag. For more details, see [**bos**(8)](/bos/8.md).

- **-localauth**

  Constructs a server ticket using a key from the local */etc/openafs/server/KeyFile* or */etc/openafs/server/KeyFileExt* 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 [**bos**(8)](/bos/8.md).

- **-help**

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

## EXAMPLES

The following example command overwrites the */usr/lib/openafs/kaserver* file on the machine `"fs4.example.com"` with its `".BAK"` version, and the current `".BAK"` version by the `".OLD"` version.

```
   % bos uninstall -server fs4.example.com -file kaserver
```

## PRIVILEGE REQUIRED

The issuer must be listed in the */etc/openafs/server/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.

The **bos uninstall** command cannot be run against servers running in restricted mode.
