NAME
uname - Displays information about the operating system SYNOPSIS
uname [-amnrsvp] uname [-S system-name] The uname command displays system information or sets the system name. STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: uname: XCU5.0, SVID 4 Refer to the standards(5) reference page for more information about industry standards and associated tags. OPTIONS
Displays all information specified with the -m, -n, -r, -s, and -v options. Displays the type of hardware running the system. Displays the name of the node (this may be a name that the system is known by to a communications network). [Tru64 UNIX] Displays the processor type of the current host. Displays the release number of the operating system. Displays the name of the implementation of the operating system. (This option is on by default.) [Tru64 UNIX] Changes the name of the system to system_name. The system_name argument is restricted to SYS_NMLN-1 characters. The value of SYS_NMLN is implementation specific and is defined in /usr/include/sys/utsname.h. Only users with appropriate privileges can use this option. Displays the operating system version. OPERANDS
None DESCRIPTION
The uname command writes system information to standard output. This command is used primarily to determine which system you are using. The options cause selected information returned by the uname() call to be displayed. NOTES
When the -a option is used, output is displayed in the order: <system> <node> <release> <version> <hardware> When you request information by specifying the individual options, the appropriate information is displayed in the order indicated. [Tru64 UNIX] If the -p option is used, processor information is appended to the output line. The output of uname may include embedded blank spaces, so you should use caution when passing the output to parsing algorithms. EXIT STATUS
The following exit values are returned: The requested information has been successfully written. An error occurred. EXAMPLES
To display the complete system name and version banner, enter: uname -a ENVIRONMENT VARIABLES
The following environment variables affect the execution of uname: Provides a default value for the internationalization variables that are unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari- ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value, overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multibyte characters in arguments). Determines the locale for the for- mat and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the processing of LC_MESSAGES. FILES
System name information header file. Node specific configuration file. SEE ALSO

NAME
jobs - Displays status of jobs in the current session SYNOPSIS
jobs [-l | -p] job_id... [Tru64 UNIX] jobs [-n] job_id... Note The C shell has a built-in version of the jobs command. If you are using the C shell, and want to guarantee that you are using the command described here, you must specify the full path /usr/bin/jobs. See the csh(1) reference page for a description of the built-in command. STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: jobs: XCU5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. OPTIONS
Provides more information about each job listed. This information includes the job number, current job, process group ID, state and the command that formed the job. Displays only the process IDs for the process group leaders of the selected jobs. [Tru64 UNIX] Displays jobs that have stopped or exited since last notified. By default, the jobs utility displays the status of all stopped jobs, running background jobs and all jobs whose status has changed and has not been reported by the shell. OPERANDS
Specifies the jobs for which the status is to be displayed. If no job_id operand is given, the status information for all jobs is dis- played. The format of job_id is described in the Jobs section of the ksh(1) reference page. DESCRIPTION
The jobs utility displays the status of jobs that were started in the current shell environment. When jobs reports the termination status of a job, the shell removes its process ID from the list of those "known in the current shell exe- cution environment". See the Jobs section of the ksh(1) reference page. RESTRICTIONS
The jobs utility does not work as expected when it is operating in its own utility execution environment because that environment has no applicable jobs to manipulate. EXIT STATUS
The following exit values are returned: Successful completion. An error occurred. ENVIRONMENT VARIABLES
The following environment variables affect the execution of jobs: Provides a default value for the internationalization variables that are unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari- ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value, overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multibyte characters in arguments). Determines the locale used to affect the format and contents of diagnostic messages written to standard error and informative messages written to standard output. Determines the location of message catalogues for the processing of LC_MESSAGES. SEE ALSO
