The MagniComp(tm) SysInfo(tm) program displays various types of information about the local host's hardware and operating system (OS) software. It is intended to provide information in both human readable (GUI and/or command line) and program parsable formats. System Administrators can use MagniComp(tm) SysInfo(tm) to obtain hardware asset information and OS configuration information. Programs which use MagniComp(tm) SysInfo(tm) can obtain this information in a platform independent manner.

The amount of information displayed varies by operating system. Here are some of the types of information that may be provided:

- Host name
- Host name aliases
- Host network addresses
- Host ID
- System serial number
- Manufacturer of the system's hardware
- System model name
- CPU type
- Application architecture
- Kernel architecture
- Amount of main memory
- Operating system name
- Operating system version
- Kernel version
- Install hardware (device) information
- Kernel parameters
- System configuration parameters
- Installed software packages

By default MagniComp(tm) SysInfo(tm) will attempt to start it's Graphical User Interface (GUI) if the $DISPLAY environment variable is set and the Tk module is available in perl(1). If $DISPLAY is not set or Tk is not available or the -nw option is specified, MagniComp(tm) SysInfo(tm) will output to the command line. See mcsysinfogui(1) for details on GUI usage.

When command line output is used MagniComp(tm) SysInfo(tm) will be default display a "medium" level of output suitable for a quick glance at system configuration information. The -msglevel all option provides the maximum amount of system information.

The default command line output format is suitable for most humans. A program parsable output format is available by specifying:

-repsep '|' -format report

Please see mcsysinfoc(3) for a description of the C API and mcsysinfoperl(3) for the perl(1) API.

The scope of the information presented can by limited by classes using the ``-class Name'' option. Further selection can by made specifying the class of information and a specific item using ``-class Name -show Item''

Upon startup, MagniComp(tm) SysInfo(tm) searches for a configuration file to parse. If the -configfile option is given, the specified configuration file will be used. Otherwise MagniComp(tm) SysInfo(tm) will search for a suitable configuration file. Searching stops when the first configuration file is found. The following search order is used:

/etc/ ConfDir/${OSname}_${OSver}.cf ConfDir/${OSname}_${OSmajver}.cf ConfDir/${OSname}.cf ConfDir/
ConfDir is /usr/local/sysinfo/config by default, but can be overridden with the -configdir option or by specifying

ConfDir Dir
in the /etc/ file. See mcsysinfocf(5) for more information.

If the file /etc/sysmodel exists, the first line of the file is read and used as the system model name.  


-be path
Use Path as the pathname to the back-end SysInfo program to use.
-cfdir DirName
This option is obsoleted by the -configdir option.
-cffile FileName
This option is obsoleted by the -configfile option.
-configdir DirName
Specify the name of the directory to use to find format configuration files.
-configfile FileName
Specify the name of a format configuration file to use. If the specified FileName cannot be opened for any reason, an error message is displayed and the program will exit.
Print the software's copyright message and exit.
-class Name1,Name2,...
Limit information to a specific class or classes of information. The default class is General.
Normally MagniComp(tm) SysInfo(tm) checks upon startup to make sure it's running on the same platform (OS Name, OS Version, CPU Type, and CPU Archecture (on some platforms)) as it was built on. This option overrides/disables this check. Using this option usually means that the information provided may be false or incomplete.
-format FormatType
Display output in FormatType format. Valid FormatType values are:
Output is suitible for human viewing. This is the default.
Output is in a format suitable for parsing by a program. Entries are printed one per line with fields seperated by ``|'' (vertical pipe) by default. The -repsep option can be used to change this value.
-infile file
Use file as the source of data to display instead of probing system for data. The file should contain data in sysinfo -format report format (see mcsysinforeport(1) ) This option is only used when using the SysInfo(tm) GUI.
-msgclass msgclass1,msgclass2,...
Specify which class of messages should be output. The default value for -msgclass is info,warn,cerror. The list of possible msgclass values are:
All of the below classes except for debug.
Display normal informational messages. All the actual useful bits of information about your system are output as msgclass info.
Display warning messages about any condition that occured while MagniComp(tm) SysInfo(tm) is running which may affect what information is found. Normally these are problems such as MagniComp(tm) SysInfo(tm) not running with the right permissions or certain things are missing from the system which are not required, but may result in incomplete information.
Display general error messages. These are non-fatal errors which are usually quite normal. For instance, a certain type of query (such as a ioctl() call) of a device fails because it's not supported on that particuliar model.
Display critical errors which prevent MagniComp(tm) SysInfo(tm) from continuing further.
Print debugging information. Lots of information you normally don't want to see, but which is very valuable for debugging problems with MagniComp(tm) SysInfo(tm).
-msglevel msglevel1,msglevel2,...
Set the level of messages that are shown. msglevels is a comma separated list of values used to determine what levels of message will be displayed. The list of possible msglevel values are:
All possible levels of information. This option provides the maximum amount of detailed information about a system.
Display output in terse format. The affect of this option is dependent on the Class of information being displayed. It usually results in the labels for each output value being suppressed. This is useful if you are running MagniComp(tm) SysInfo(tm) from a script to obtain a few specific values (e.g. System Model, CPU Architecture, etc).
More than terse but less than all.
General level of information useful for a quick look at overall system configuration. This is the default.
Like general but with more descriptive information.
Similiar to general and descriptions
No windows. Force SysInfo(tm) to use it's command line interface (CLI) even if the environment is capable of running the SysInfo(tm) GUI.
-list [ class|format|msgclass|msglevel|show|type ]
List the possible values that may be used with an option. With no arguments are specified, a list is valid arguments is displayed. When an argument is supplied, the information specific to that argument is displayed.
-offset amount
Set the number of spaces to offset (indent) when printing device information.
-repsep string
Change the field seperator string used with -format report to be string. The default is ``|'' (vertical pipe).
-show item1,item2,...
Show information only about each comma separated item. Run sysinfo -list show for a list of valid item arguments. If the -class option is not specified, then the General class is assumed.
When +swfiles is specified and software class information is being displayed, a list of files and file data is displayed for all files belonging to each package. The default is (-swfiles) not to display file data.
-type item1,item2,...
Limit information to a specific type of item as specified by item1,item2,... Run sysinfo -list type for a list of valid item arguments.
Enable (+unknown) or disable (-unknown) showing devices that appear to be present on the system, but are not "known" to MagniComp(tm) SysInfo(tm). This option is disabled by default.
Enable (+unused) or disable (-unused) showing partitions that do not appear to be in use. The default is -unused.
Enable (+useconfig) or disable (-useconfig) use of configuration files. This option is useful if you want to run MagniComp(tm) SysInfo(tm) without having the configuration files installed. Note that only certain types of information - such as some of the General values - will be available without use of configuration files. The default is +useconfig.
Enable (+useprom) or disable (-useprom) using values obtained from the system PROM instead of intepreting values obtained directly from the kernel. Certain values are normally obtained by looking up a variable in the kernel and checking the result against a table of values compiled into MagniComp(tm) SysInfo(tm). By enabling this option, MagniComp(tm) SysInfo(tm) will attempt to obtain certain values from the system PROM. This support is currently limited to the System Model value. Support is also limited to those machines which support such a system PROM.
Show version information for MagniComp(tm) SysInfo(tm).


The following command displays the maximum amount of information about a system:
sysinfo -msglevel all

A very useful command to use when DEBUGGING MagniComp(tm) SysInfo(tm) is:

sysinfo -msglevel all -msgclass all,debug

The following example outputs just the System Model:

sysinfo -msglevel terse -show model

This command will limit the output to just information about Kernel variables:

sysinfo -class kernel

The following command provides the maximum amount of data in a software parsable format:

sysinfo -msglevel all -format report -repsep '|'






/usr/local/sysinfo/config      - Directory of config files

/etc/ - Master configuration file
/etc/sysmodel  - Explicitly set the CPU model name


mcsysinfogui(1), mcsysinforeport(1), mcsysinfoc(3), mcsysinfoperl(3), mcsysinfocf(5), gethostid(2), gethostname(2), gethostbyname(3)  


%x: Unknown CPU type.
The CPU model for the current host could not be determined.
Information could not be determined for this item.


Not all operating systems support interfaces to various pieces of information that MagniComp(tm) SysInfo(tm) supports.

Some devices, mostly devices that use removable media such as tape drives and floppy disks, are only indicated (shown) as present if media is loaded in the device and it's on-line. This occurs because the OS does not provide a software interface to query the device when media is not loaded.

SunOS allows only one process at a time to have /dev/openprom open. This may result in certain pieces of information not always showing up consistantly. When in doubt, enable debugging (-msgclass debug).

Under SunOS 5.4 the ROM Version field is blank. This is due to a change made by Sun in libkvm. Sun patch 102555-01 is suppose to fix this problem. MagniComp(tm) Sysinfo(tm) uses a new OBP interface in SunOS 5.5 that by-passes this problem.

Under SunOS 4.x the Serial Number field is left blank since the kernel usually returns incorrect information.

Under SunOS 5.x the Serial Number field will show the serial number as obtained from the system's IDPROM. This serial number has no correspondence with the system serial number that appears on the back of your machine.

Under SunOS there is no way to tell the difference between an MC68020 (like the 3/60) and MC68030 (like the 3/80) based machine.
