In this example, the SHOW TERMINAL command displays the full terminal characteristics.
Displays the current date and time.
SHOW [DAY]TIME
None.
$ SHOW TIME
3-NOV-2001 00:02:00
|
The SHOW TIME command in this example displays the current date and time.
Displays the first translation found for the specified logical name. You can specify the tables that are searched.Requires read (R) access to a logical name table to display information about any logical name cataloged in that table.
SHOW TRANSLATION logical-name
logical-name
Specifies the logical name whose translation you want to display.
The SHOW TRANSLATION command searches one or more logical name tables for a specified logical name and returns the equivalence name of the first match found. You can specify the tables you want to search. If you do not specify a table, SHOW TRANSLATION searches the tables defined by the logical name LNM$DCL_LOGICAL.The logical name LNM$DCL_LOGICAL contains the list of logical name tables and the order in which they are searched. Unless LNM$DCL_LOGICAL has been redefined for your process, the process, job, group, and system logical name tables are searched, in that order. The first match found is displayed. (To see how LNM$DCL_LOGICAL is defined for your process, enter the command SHOW LOGICAL /TABLE=LNM$DIRECTORIES LNM$DCL_LOGICAL.)
If a table contains more than one entry with the same name, but each name has a different mode, then the translation for the name with the outermost (least privileged) mode is returned.
The SHOW TRANSLATION command is similar to the SHOW LOGICAL command; however, the SHOW TRANSLATION command is executed within the DCL command interpreter (the SHOW LOGICAL command calls an image). Therefore, the SHOW TRANSLATION command does not cause the current image to exit and does not deassign user mode logical names. Also, the SHOW TRANSLATION command does not display iterative translations of a name.
/TABLE=name
Searches the specified table. The default value for the name parameter is LNM$DCL_LOGICAL.If you specify the table name by using a logical name that translates to more than one table, then each table is searched in the order specified until a match is found.
| #1 |
|---|
$ SHOW TRANSLATION PAYROLL
PAYROLL = DISK1:[ACCOUNTS.WORKING]FACTOR1.DAT;37 (LNM$PROCESS_TABLE)
|
The SHOW TRANSLATION command in this example displays the translation for the logical name PAYROLL and also displays the name of the table where the logical name was found. In this example, PAYROLL was found in LNM$PROCESS_TABLE, the process logical name table.
| #2 |
|---|
$ DEFINE DISK DKA1:
$ DEFINE/GROUP DISK DKA2:
$ SHOW TRANSLATION DISK
DISK = DKA1:(LNM$PROCESS_TABLE)
|
The DEFINE commands in this example place entries for the logical name DISK in both the process and group logical name tables. Then, the SHOW TRANSLATION command shows the translation associated with the logical name DISK. By default, the process, job, group, and system tables are searched (in that order). The first match found is displayed. The logical name DISK from the process table (LNM$PROCESS_TABLE) is displayed because it is found before the name DISK in the group table.
| #3 |
|---|
$ RUN ORION
[Ctrl/Y]
$ SHOW TRANSLATION TERMINAL
TERMINAL = _TTT3: (LNM$PROCESS_TABLE)
$ CONTINUE
|
The RUN command in this example executes the image ORION.EXE. After the Ctrl/Y function interrupts the image, the SHOW TRANSLATION command displays a logical name assignment. The CONTINUE command resumes the execution of the image.
| #4 |
|---|
$ SHOW TRANSLATION/TABLE=LNM$SYSTEM USER
USER = "DKA2:" (LNM$SYSTEM_TABLE)
|
The SHOW TRANSLATION command in this example displays the translation for the logical name USER. Because a table name is specified, the SHOW TRANSLATION command does not use the default search order. Only the specified table, LNM$SYSTEM, is searched. LNM$SYSTEM is the system logical name table.
| #5 |
|---|
$ DEFINE/TABLE=LNM$PROCESS_DIRECTORY MYPROC -
_$ TEST_TABLE, LNM$PROCESS
$ SHOW TRANSLATION/TABLE=MYPROC FILER
FILER = "[SMITH.FILER]" (TEST_TABLE)
|
In this example, MYPROC defines a list of logical name tables that you want searched. It asks the system to first search TEST_TABLE (a user-defined table) and then to search LNM$PROCESS (the process logical name table). MYPROC is stored in LNM$PROCESS_DIRECTORY, the process directory table. When you enter the SHOW TRANSLATION command to find FILER in the MYPROC table, the tables TEST_TABLE and LNM$PROCESS are searched, in that order. The first match found is displayed.
Displays the user name and node name (in an OpenVMS Cluster environment) of interactive, subprocess, and batch users on the system.
SHOW USERS [username]
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.
/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.
