qmgr: pbs batch system manager

NAME

qmgr - pbs batch system manager

SYNOPSIS

qmgr [-a] [-c command] [-e] [-n] [-z] [server...]

DESCRIPTION

The qmgr command provides an administrator interface to the batch system.

The command reads directives from standard input. The syntax of each directive is checked and the appropriate request is sent to the batch server or servers.

The list or print subcommands of qmgr can be executed by general users. Creating or deleting a queue requries PBS Manager privilege. Setting or unsetting server or queue attributes requires PBS Operator or Manager privilege.

OPTIONS

-a

Abort qmgr on any syntax errors or any requests rejected by a server.

-c command

Execute a single and exit qmgr .

-e

Echo all commands to standard output.

-n

No commands are executed, syntax checking only is performed.

-z

No errors are written to standard error.

OPERANDS

The operands identify the name of the batch server to which the administrator requests are sent. Each conforms to the following syntax:

where is the network name of the host on which the server is running and is the port number to which to connect. If is not specified, the default port number is used.

If is not specified, the administrator requests are sent to the local server.

STANDARD INPUT

The qmgr command reads standard input for directives until end of file is reached, or the exit or quit directive is read.

STANDARD OUTPUT

If Standard Output is connected to a terminal, a command prompt will be written to standard output when qmgr is ready to read a directive.

If the option is specified, qmgr will echo the directives read from standard input to standard output.

STANDARD ERROR

If the option is not specified, the qmgr command will write a diagnostic message to standard error for each error occurrence.

EXTENDED DESCRIPTION

If qmgr is invoked without the option and standard output is connected to a terminal, qmgr will write a prompt to standard output and read a directive from standard input.

Commands can be abbreviated to their minimum unambiguous form. A command is terminated by a new line character or a semicolon, ";", character. Multiple commands may be entered on a single line. A command may extend across lines by escaping the new line character with a back-slash "\".

Comments begin with the # character and continue to end of the line. Comments and blank lines are ignored by qmgr.
