uname [–aImnrsv]
Note: Option –I is an uppercase i, not a lowercase L.
The uname command lets shell scripts and other programs determine configuration
information about the machine upon which the shell is running.
The following options select the information to be displayed:
–a All fields (equivalent to –mnrsv).
–I The IBM current product name information. This option affects the value of
the system name, release and version fields. This option may affect the
output of the –a, –r, –s and –v options. When –I is not specified (the
default), the OS/390 product name information is returned.
–m The processor or machine type.
–n The node name of this particular machine. The node name is set by the
SYSNAME sysparm (specified at IPL), and it usually differentiates machines
running at a single location.
–r The release (minor version) number of the operating system.
–s The name of the operating system. This is the default output, when no
options are given.
–v The version (major version) number of the operating system.
