.SH NAME
livesys \- Reports the configured CPU/operating system type
.SH SYNOPSIS
.IX Header "SYNOPSIS"
\&\fBlivesys\fR
.SH DESCRIPTION
.IX Header "DESCRIPTION"
The \fBlivesys\fR command displays the string stored in kernel memory that
indicates the local machine's CPU/operating system (OS) type,
conventionally called the \fIsysname\fR.  The Cache Manager substitutes this
string for the \fR\f(CI@sys\fR\fI\fR variable which can occur in AFS pathnames; the
\&\fIOpenAFS Quick Start Guides\fR and \fIOpenAFS Administration Guide\fR explain
how using \fI\fR\f(CI@sys\fR\fI\fR can simplify cell configuration.
.PP
To set a new value in kernel memory, use the \fBfs sysname\fR command, which
can also be used to view the current value.  If a sysname list was set
using \fBfs sysname\fR, only the first value in the list will be reported by
\&\fBlivesys\fR.
.SH CAUTIONS
.IX Header "CAUTIONS"
To see the full sysname list, use \fBfs sysname\fR rather than this command.
\&\fBlivesys\fR is mostly useful for scripts that need to know the primary
sysname for the local system (to create directories that will later be
addressed using \fR\f(CI@sys\fR\fI\fR, for example).
.PP
\&\fBlivesys\fR first appeared in OpenAFS 1.2.2.  Scripts that need to support
older versions of AFS should parse the output of \fBfs sysname\fR or use
\&\fBsys\fR.
.SH OUTPUT
.IX Header "OUTPUT"
The machine's system type appears as a text string, by itself, on a single
line.
.SH EXAMPLES
.IX Header "EXAMPLES"
The following example shows the output produced on a Linux system with a
2.6 kernel:
