osinfo - gather information regarding the running operating system

The osinfo command displays information regarding the operating system, gathered via WBEM using the PG_OperatingSystem class supported by the OperatingSystem Provider (bundled with OpenPegasus). osinfo requires the CIM Server to be installed and running.

By default, the information is formatted for display, converting CIMDateTime strings into a more user-readable format (see Examples), and converting the total number of seconds of uptime into the appropriate number of days, hours, minutes, and seconds.

If a property value is unavailable, it will be shown as "Unknown"

-c

Use the CIM formats for DateTime and SystemUpTime values (not the formatting done by default). As specified by the DMTF, the CIMDateTime format is yyyymmddhhmmss.mmmmmmsutc, where yyyy is a 4-digit year, mm is the month, dd is the day, hh is the hour on a 24-hour clock, mm is the minute, ss is the second, mmmmmm is the number of microseconds, s is a "+" or "-" indicating the sign of the UTC (Universal Time Code) correction field (since the DateTime is returned in the local time zone of the system), and utc is the offset from UTC in minutes.

-h hostname

Connect to the CIM Server on the specified host. If this option is not specified, osinfo connects to the localhost.

--help

Display command usage information.

-p portnumber

Connect to the CIM Server on the specified port number. If this option is not specified, osinfo connects to the default port for the wbem-http service, or if the -s option is specified, to the default port for the wbem-https service.

-s

Enable the use of the SSL protocol between osinfo and the CIM server. The -s option should be specified if the CIM Server on the specified hostname/portnumber expects clients to connect using HTTPS.

-t timeout

Wait the specified number of milliseconds on sending a request, before timing out if no response has been received. The timeout value must be an integer value greater than 0.

-u username

Connect as the specified R username . If username is not specified, the current logged in user is used for authentication. This option is ignored if neither hostname nor portnumber is specified.

--version

Display CIM Server version.

-w password

Authenticate the connection using the specified password . This option is ignored if neither hostname nor portnumber is specified. WARNING: A password should not be specified on the command line on a multi-user system, since command-line options are typically world-readable for a short window of time. If the remote host requests authentication and this option is not specified, osinfo will prompt for the password.

When an error occurs, an error message is written to stderr and an appropriate value is returned. The following values are returned:

0

Success

1

Error

The osinfo command requires that the CIM Server is running.

osinfo error: Cannot connect

The CIMOM is not running. Start the CIMOM with the cimserver command and re-run osinfo .

Run the default osinfo command.
