When options are speci- + fied, symbols representing one or more system character- + istics shall be written to the standard output. The for- + mat and contents of the symbols are implementation- + defined. On systems conforming to the System Interfaces + volume of IEEE Std 1003.1-2001, the symbols written + shall be those supported by the uname() function as + defined in the System Interfaces volume of + IEEE Std 1003.1-2001. + +OPTIONS + The uname utility shall conform to the Base Definitions + volume of IEEE Std 1003.1-2001, Section 12.2, Utility + Syntax Guidelines. + + The following options shall be supported: + + -a Behave as though all of the options -mnrsv were + specified. + + -m Write the name of the hardware type on which the + system is running to standard output. + + -n Write the name of this node within an implementa- + tion-defined communications network. + + -r Write the current release level of the operating + system implementation. + + -s Write the name of the implementation of the oper- + ating system. + + -v 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. + +OPERANDS + None. + +STDIN + Not used. + +INPUT FILES + None. + +ENVIRONMENT VARIABLES + The following environment variables shall affect the + execution of uname: + + LANG Provide a default value for the internationaliza- + tion variables that are unset or null. (See the + Base Definitions volume of IEEE Std 1003.1-2001, + Section 8.2, Internationalization Variables for + the precedence of internationalization variables + used to determine the values of locale cate- + gories.) + + LC_ALL If set to a non-empty string value, override the + values of all the other internationalization + variables. + + LC_CTYPE + 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). + + LC_MESSAGES + Determine the locale that should be used to + affect the format and contents of diagnostic mes- + sages written to standard error. + + NLSPATH + Determine the location of message catalogs for + the processing of LC_MESSAGES . + + +ASYNCHRONOUS EVENTS + Default. + +STDOUT + By default, the output shall be a single line of the + following form: + + + "%s\n", <sysname> + + 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 writ- + ten; all such symbols shall be written at the end of the + line of output before the <newline>. + + If options are specified to select different combina- + tions of the symbols, only those symbols shall be writ- + ten, in the order shown above for the -a option. If a + symbol is not selected for writing, its corresponding + trailing <blank>s also shall not be written. + +STDERR + The standard error shall be used only for diagnostic + messages. + +OUTPUT FILES + None. + +EXTENDED DESCRIPTION + None. + +EXIT STATUS + The following exit values shall be returned: + + 0 The requested information was successfully writ- + ten. + + >0 An error occurred. + + +CONSEQUENCES OF ERRORS + Default. + + The following sections are informative. + +APPLICATION USAGE + Note that any of the symbols could include embedded + <space>s, which may affect parsing algorithms if multi- + ple options are selected for output. + + The node name is typically a name that the system uses + to identify itself for inter-system communication + addressing. + +EXAMPLES + The following command: + + + uname -sr + + writes the operating system name and release level, sep- + arated by one or more <blank>s. + +RATIONALE + It was suggested that this utility cannot be used + portably since the format of the symbols is implementa- + tion-defined. The POSIX.1 working group could not + achieve consensus on defining these formats in the + underlying uname() function, and there was no expecta- + tion that this volume of IEEE Std 1003.1-2001 would be + any more successful. Some applications may still find + this historical utility of value. For example, the sym- + bols could be used for system log entries or for compar- + ison with operator or user input. + +FUTURE DIRECTIONS + None. + +SEE ALSO + The System Interfaces volume of IEEE Std 1003.1-2001, + uname() + +COPYRIGHT + Portions of this text are reprinted and reproduced in + electronic form from IEEE Std 1003.1, 2003 Edition, + Standard for Information Technology -- Portable Operat- + ing System Interface (POSIX), The Open Group Base Speci- + fications Issue 6, Copyright (C) 2001-2003 by the Insti- + tute of Electrical and Electronics Engineers, Inc and + The Open Group.
