# bos\_exec(8)

Executes a command on a remote server machine

## NAME

bos\_exec - Executes a command on a remote server machine

## SYNOPSIS

**bos exec** **-server** \<*machine name*\> **-cmd** \<*command to execute*\>\
     \[**-cell** \<*cell name*\>\] \[**-noauth**\] \[**-localauth**\] \[**-help**\]

**bos e** **-s** \<*machine name*\> **-cm** \<*command to execute*\>\
     \[**-ce** \<*cell name*\>\] \[**-n**\] \[**-l**\] \[**-h**\]

## DESCRIPTION

The **bos exec** command executes the indicated command on the file server machine named by the **-server** argument. Its intended use is to reboot the machine, using the */sbin/reboot* command or equivalent.

## OPTIONS

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

  Indicates the server machine on which to execute the command.  Identify the machine by IP address or its host name (either fully-qualified or abbreviated unambiguously). For details, see [**bos**(8)](/bos/8.md).

- **-cmd** \<*command to execute*\>

  Specifies the complete local disk pathname of the command to execute (for example, */sbin/reboot*). Surround this argument with double quotes (`""`) if the command contains one or more spaces.

- **-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* 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 command reboots the machine `"fs2.example.com"`. The issuer has previously issued the **bos shutdown** command to shutdown all processes cleanly.

```
   % bos exec -server fs2.example.com -cmd /sbin/shutdown -r now
```

## 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 exec** command is not available on servers running in restricted mode.
