Manual Reference Pages - SYS (1)
sys - Reports the compile-time CPU/operating system type
The sys command displays the string set at compile time that indicates
the local machines CPU/operating system (OS) type, conventionally called
the sysname. This string is the default for the value stored in kernel
memory. The Cache Manager substitutes this string for the @sys
variable which can occur in AFS pathnames; the OpenAFS Quick Start
Guide and OpenAFS Administration Guide explain how using @sys can
simplify cell configuration.
To set a new value in kernel memory, use the fs sysname command. To
view the current value set in the kernel, use either fs sysname or
You almost always want to use livesys rather than this command. The
sys command displays a single value hard-coded at compile time. It
does not query the Cache Manager for the current value and it does not
report sysname lists. If you have changed the local system type with fs
sysname, or if you run a version of sys compiled differently than the
Cache Manager running on the system, the value returned will not match the
behavior of the Cache Manager. The only reason to use sys is that
livesys wasnt available in older versions of AFS.
The machines system type appears as a text string:
