FS_SYSNAME(1)						       AFS Command Reference						     FS_SYSNAME(1)

NAME
       fs_sysname - Reports or sets the CPU/operating system type

SYNOPSIS
       fs sysname [-newsys <new sysname>]+ [-help]

       fs sy [-n <new sysname>]+ [-h]

DESCRIPTION
       The fs sysname command sets or displays the local machine's CPU/operating system type as recorded in kernel memory. The Cache Manager
       substitutes the string for the @sys variable which can occur in AFS pathnames; the OpenAFS Quick Beginnings and OpenAFS Administration
       Guide explain how using @sys can simplify cell configuration. It is best to use it sparingly, however, because it can make the effect of
       changing directories unpredictable.

       The command always applies to the local machine only. If issued on an NFS client machine accessing AFS via the NFS/AFS Translator, the
       string is set or reported for the NFS client machine. The Cache Manager on the AFS client machine serving as the NFS client's NFS/AFS
       translator machine stores the value in its kernel memory, and so can provide the NFS client with the proper version of program binaries
       when the user issues commands for which the pathname to the binaries includes @sys. There is a separate record for each user logged into
       the NFS client, which implies that if a user adopts a new identity (UNIX UID) during a login session on the NFS client -- perhaps by using
       the UNIX su command -- he or she must verify that the correct string is set for the new identity also.

OPTIONS
       -newsys <new sysname>
	   Sets the CPU/operating system indicator string for the local machine. This option may be used multiple times in the same invocation,
	   which sets @sys to an array of values. When @sys contains an array of values, the first value that matches a path is used.

	   If this argument is omitted, the output displays the current setting instead. AFS uses a standardized set of strings; consult the
	   OpenAFS Quick Beginnings or OpenAFS Release Notes.

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

OUTPUT
       When the -newsys argument is omitted, the output reports the machine's system type in the following format:

	  Current sysname is '<system_type>'

       When the -newsys argument is included, the output is the following:

	  fs: new sysname list set.

EXAMPLES
       The following example shows the output produced on a Sun SPARCStation running Solaris 5.7:

	  % fs sysname
	  Current sysname is 'sun4x_57'

       The following command defines a machine to be a IBM RS/6000 running AIX 4.2:

	  % fs sysname -newsys rs_aix42

       The following command defines a machine to be Mac OS X PPC and a custom type 'foo'. The second command queries the new sysname:

	  % fs sysname -newsys ppc_darwin_80 -newsys foo
	  fs: new sysname list set.
	  % fs sysname
	  Current sysname list is 'ppc_darwin_80' 'foo'

       If @sys is "ppc_darwin_80 foo", then "cd @sys" will try to change to the "ppc_darwin_80" directory. If the "ppc_darwin_80" directory
       doesn't exist, then the "foo" directory is tried.

PRIVILEGE REQUIRED
       To display the current setting, no privilege is required. To include the -newsys argument on an AFS client machine, the issuer must be
       logged in as the local superuser "root".
