| 5 | .TH MACHTYPE 1 "May 14 1996" |
|---|
| 6 | .SH NAME |
|---|
| 7 | machtype \- Print machine type to standard output |
|---|
| 8 | .SH SYNOPSIS |
|---|
| 9 | .B machtype |
|---|
| 10 | [-c] [-d] [-r] [-M] [-v] [-A] [-L] [-P] [-N] [-E] [-S] [-C] [-k kernel] [-m memory] |
|---|
| 11 | .SH DESCRIPTION |
|---|
| 12 | .I Machtype |
|---|
| 13 | prints the CPU type to standard output. It prints "sun4" when run on a |
|---|
| 14 | Sun and "sgi" when run on an SGI. |
|---|
| 15 | .TP |
|---|
| 16 | .B -c |
|---|
| 17 | Print the specific cpu type (e.g. SPARC/5 or IP22). |
|---|
| 18 | .TP |
|---|
| 19 | .B -d |
|---|
| 20 | Print the types of display attached to the system (e.g. "cgthree"). |
|---|
| 21 | .TP |
|---|
| 22 | .B -r |
|---|
| 23 | Print the types of any disk drives attached to the system, one to a |
|---|
| 24 | line, as in "SUN0535". |
|---|
| 25 | .TP |
|---|
| 26 | .B -M |
|---|
| 27 | Print the physical memory present, in kilobytes. |
|---|
| 28 | .TP |
|---|
| 29 | .B -k |
|---|
| 30 | Override the default kernel to examine for symbols. |
|---|
| 31 | .TP |
|---|
| 32 | .B -m |
|---|
| 33 | Override the default memory image used to look up the specific cpu |
|---|
| 34 | type, displays, and disk drives. |
|---|
| 35 | .TP |
|---|
| 36 | .B -v |
|---|
| 37 | Verbose output (suitable for humans to read, instead of computers). |
|---|
| 38 | .TP |
|---|
| 39 | .B -A |
|---|
| 40 | Print out the release that machtype was compiled under. |
|---|
| 41 | .TP |
|---|
| 42 | .B -P |
|---|
| 43 | Print out the version of the Athena system packs attached, from |
|---|
| 44 | .I /srvd/.rvdinfo |
|---|
| 45 | .TP |
|---|
| 46 | .B -L |
|---|
| 47 | Print out the version of Athena installed on the local system from |
|---|
| 48 | .I /etc/athena/version. |
|---|
| 49 | .TP |
|---|
| 50 | .B -N |
|---|
| 51 | Print out the name of the base operating system machtype was compiled |
|---|
| 52 | under; if used with the "-v" flag, the version number of the OS will |
|---|
| 53 | be included as well. Current values for the name of the base OS are |
|---|
| 54 | "SunOS" and "IRIX". |
|---|
| 55 | .TP |
|---|
| 56 | .B -E |
|---|
| 57 | Print out the version number of the base operating system machtype was |
|---|
| 58 | compiled under. |
|---|
| 59 | .TP |
|---|
| 60 | .B -S |
|---|
| 61 | Print out the "Athena System" name for the current architecture. This |
|---|
| 62 | value is normally stored in the environment variable ATHENA_SYS, and |
|---|
| 63 | ideally corresponds to the AFS system name for the same machine |
|---|
| 64 | assuming the machine were running AFS. This value is used in the Athena |
|---|
| 65 | environment as part of a scheme for laying out filesystems containing |
|---|
| 66 | binaries for multiple architectures. See \fIlockers\fR(7) for more |
|---|
| 67 | information. |
|---|
| 68 | .TP |
|---|
| 69 | .B -C |
|---|
| 70 | Print out a colon-separated list of "Athena System" names that are |
|---|
| 71 | compatible with the current architecture. This value is normally |
|---|
| 72 | stored in the environment variable ATHENA_SYS_COMPAT, and is used by |
|---|
| 73 | \fIathdir\fR(1) and \fIadd\fR(1) as a set of fallback values when a |
|---|
| 74 | locker doesn't have binaries for the actual Athena System name. |
|---|
| 75 | .PP |
|---|
| 76 | .I Machtype |
|---|
| 77 | is useful for conditionalizing shell scripts, .login files, etc. in an |
|---|
| 78 | environment that contains filesystems shared across several different |
|---|
| 79 | architectures. |
