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".
