| 3 | sys - Reports the compile-time CPU/operating system type | |
| 4 | ||
| 5 | =head1 SYNOPSIS | |

| 7 | =for html | |

| 10 | B<sys> | |
| 11 | ||

| 13 | </div> | |

| 15 | =head1 DESCRIPTION | |
| 16 | ||
| 17 | The B<sys> command displays the string set at compile time that indicates | |
| 18 | the local machine's CPU/operating system (OS) type, conventionally called | |
| 19 | the I<sysname>. This string is the default for the value stored in kernel | |
| 20 | memory. The Cache Manager substitutes this string for the I<@sys> | |
| 21 | variable which can occur in AFS pathnames; the I<OpenAFS Quick Start | |
| 22 | Guide> and I<OpenAFS Administration Guide> explain how using I<@sys> can | |
| 23 | simplify cell configuration. | |
| 24 | ||
| 25 | To set a new value in kernel memory, use the B<fs sysname> command. To | |
| 26 | view the current value set in the kernel, use either B<fs sysname> or | |
| 27 | B<livesys>. | |
| 28 | ||
| 29 | =head1 CAUTIONS | |
| 30 | ||
| 31 | You almost always want to use B<livesys> rather than this command. The | |
| 32 | B<sys> command displays a single value hard-coded at compile time. It | |
| 33 | does not query the Cache Manager for the current value and it does not | |
| 34 | report sysname lists. If you have changed the local system type with B<fs | |
| 35 | sysname>, or if you run a version of B<sys> compiled differently than the | |
| 36 | Cache Manager running on the system, the value returned will not match the | |
| 37 | behavior of the Cache Manager. The only reason to use B<sys> is that | |
| 38 | B<livesys> wasn't available in older versions of AFS. | |
| 39 | ||
| 40 | =head1 OUTPUT | |
| 41 | ||
| 42 | The machine's system type appears as a text string: | |
| 43 | ||
| 44 | I<system_type> | |
| 45 | ||
| 46 | =head1 EXAMPLES | |
| 47 | ||
| 48 | The following example shows the output produced on a Sun Netra T1 | |
| 49 | running Solaris 10: | |
| 50 | ||
| 51 | % sys | |
| 52 | sun4x_510 | |
