SHOW USERS

Displays the user name and node name (in an OpenVMS Cluster environment) of interactive, subprocess, and batch users on the system.

Format

SHOW USERS [username]


Parameter

username

Specifies the user about whom you want information. The asterisk (*) and the percent sign (%) wildcard characters are allowed. If you specify a string, all users whose user names begin with the string are displayed. For example, if you specify the string MAR, all user names that begin with MAR are displayed. If no user exists whose name matches the specified string, an informational message tells you that no processes were found.

If you omit the username parameter, a list of all interactive, subprocess, and batch users is displayed.


Qualifiers

/BATCH

/NOBATCH

Displays all batch users in the OpenVMS Cluster environment. To restrict the display to users on specific nodes, use the /BATCH qualifier with the /NODE qualifier. When you use the /NOBATCH qualifier, all batch users are excluded from the display.

/CLUSTER

Displays the specified user names on all nodes in an OpenVMS Cluster environment.

/EXACT

Use with the /PAGE=SAVE and /SEARCH qualifiers to specify a search string that must match the search string exactly and must be enclosed with quotation marks (" ").

If you specify the /EXACT qualifier without the /SEARCH qualifier, exact search mode is enabled when you set the search string with the Find (E1) key.

/FULL

Displays the user name, the node name, the process name, the process identification (PID) code, terminal names (both virtual and physical), and port information of all interactive, subprocess, and batch users on the system.

/HEADING (default)

/NOHEADING

Displays a heading line above the system output. When you use the /NOHEADING qualifier, the heading line is excluded from the display.

/HIGHLIGHT[=keyword]

Use with the /PAGE=SAVE and /SEARCH qualifiers to specify the type of highlighting you want when a search string is found. When a string is found, the entire line is highlighted. You can use the following keywords: BOLD, BLINK, REVERSE, and UNDERLINE. BOLD is the default highlighting.

/INTERACTIVE

/NOINTERACTIVE

Displays all interactive processes held by users in the OpenVMS Cluster environment. To restrict the display to users on specific nodes, use the /INTERACTIVE qualifier with the /NODE qualifier. When you use the /NOINTERACTIVE qualifier, all interactive processes held by users in the OpenVMS Cluster environment are excluded from the display.

/NETWORK

/NONETWORK

Displays all network users in the OpenVMS Cluster environment. To restrict the display to users on specific nodes, use the /NETWORK qualifier with the /NODE qualifier. When you use the /NONETWORK qualifier, all network users in the OpenVMS Cluster environment are excluded from the display.

/NODE[=(name,...)]

Displays all interactive, subprocess, and batch users on the specified node or nodes. If you enter the /NODE qualifier without a value, the qualifier displays all the interactive, subprocess, and batch users on the local node.

/OUTPUT[=filespec]

/NOOUTPUT

Controls where the output of the command is sent. By default, the output of the SHOW USERS command is sent to the current SYS$OUTPUT device (usually your terminal). To send the output to a file, use the /OUTPUT qualifier followed by a file specification.

The asterisk (*) and the percent sign (%) wildcard characters are not allowed in the file specification. If you enter a partial file specification (for example, specifying only a directory), SHOW is the default file name and .LIS is the default file type.

If you enter the /NOOUTPUT qualifier, output is suppressed.

/PAGE[=keyword]

/NOPAGE (default)

Controls the display of user information on the screen.

You can use the following keywords with the /PAGE qualifier:

CLEAR_SCREEN Clears the screen before each page is displayed.
SCROLL Displays information one line at a time.
SAVE[= n] Enables screen navigation of information, where n is the number of pages to store.

The /PAGE=SAVE qualifier allows you to navigate through screens of information. The /PAGE=SAVE qualifier stores up to 5 screens of up to 255 columns of information. When you use the /PAGE=SAVE qualifier, you can use the following keys to navigate through the information:

Key Sequence Description
Up arrow key, Ctrl/B Scroll up one line.
Down arrow key Scroll down one line.
Left arrow key Scroll left one column.
Right arrow key Scroll right one column.
Find (E1) Specify a string to find when the information is displayed.
Insert Here (E2) Scroll right one half screen.
Remove (E3) Scroll left one half screen.
Select (E4) Toggle 80/132 column mode.
Prev Screen (E5) Get the previous page of information.
Next Screen (E6), Return, Enter, Space Get the next page of information.
F10, Ctrl/Z Exit. (Some utilities define these differently.)
Help (F15) Display utility help text.
Do (F16) Toggle the display to oldest/newest page.
Ctrl/W Refresh the display.

The /PAGE qualifier is not compatible with the /OUTPUT qualifier.

/SEARCH="string"

Use with the /PAGE=SAVE qualifier to specify a string that you want to find in the information being displayed. Quotation marks are required for the /SEARCH qualifier, if you include spaces in the text string.

You can also dynamically change the search string by pressing the Find key (E1) while the information is being displayed. Quotation marks are not required for a dynamic search.

/SUBPROCESS

/NOSUBPROCESS

Displays all subprocess users in the OpenVMS Cluster environment. To restrict the display to users on specific nodes, use the /SUBPROCESS qualifier with the /NODE qualifier. When you use the /NOSUBPROCESS qualifier, all subprocess users in the OpenVMS Cluster environment are excluded from the output.

/WRAP

/NOWRAP (default)

Use with the /PAGE=SAVE qualifier to limit the number of columns to the width of the screen and to wrap lines that extend beyond the width of the screen to the next line.

The /NOWRAP qualifier extends lines beyond the width of the screen and can be seen when you use the scrolling (left and right) features provided by the /PAGE=SAVE qualifier.


Examples

$ SHOW USERS
      OpenVMS User Processes at 12-MAY-2001 10:37 AM
    Total number of users = 4,  number of processes = 14
 Username     Node     Interactive  Subprocess   Batch

 VAXMAN      AAAAAA            2
      

The SHOW USERS command in this example displays the user names and node names of all current interactive, subprocess, and batch users on the system.

#2

$ SHOW USERS/NOHEADING/OUTPUT=SYSUSERS.DAT
$ TYPE SYSUSERS.DAT
