The following options shall be supported:
- Behave as though all of the options -mnrsv were specified.
- Write the name of the hardware type on which the system is running to standard output.
- Write the name of this node within an implementation-defined communications network.
- Write the current release level of the operating system implementation.
- Write the name of the implementation of the operating system.
- Write the current version level of this release of the operating system implementation.
If no options are specified, the uname utility shall write the operating system name, as if the -s option had been specified.
- Provide a default value for the internationalization variables that are unset or null. (See the Base Definitions volume of POSIX.1‐2017, Section 8.2, Internationalization Variables for the precedence of internationalization variables used to determine the values of locale categories.)
- If set to a non-empty string value, override the values of all the other internationalization variables.
- Determine the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multi-byte characters in arguments).
Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard error.
- Determine the location of message catalogs for the processing of LC_MESSAGES.
If the -a option is specified, the output shall be a single line of the following form:
"%s %s %s %s %s\n", <sysname>, <nodename>, <release>, <version>, <machine>
Additional implementation-defined symbols may be written; all such symbols shall be written at the end of the line of output before the <newline>.
If options are specified to select different combinations of the symbols, only those symbols shall be written, in the order shown above for the -a option. If a symbol is not selected for writing, its corresponding trailing <blank> characters also shall not be written.
- The requested information was successfully written.
- An error occurred.
The following sections are informative.
The node name is typically a name that the system uses to identify itself for inter-system communication addressing.
writes the operating system name and release level, separated by one or more <blank> characters.
