--- release batch jobs
qrls [-h hold_list] job_identifier...
A batch job might have one or more holds, which prevent the batch job
from executing. A batch job from which all the holds have been removed
becomes eligible for execution and is said to have been released. A
batch job hold is removed by sending a request to the batch server that
manages the batch job. The
utility is a user-accessible client of batch services that requests
holds be removed from one or more batch jobs.
utility shall remove one or more holds from those batch jobs for which

utility shall remove holds from batch jobs in the order in which their
are presented to the utility.

The following option shall be supported by the implementation:

option-argument that is a string of alphanumeric characters in the
portable character set (see the Base Definitions volume of POSIX.1-2017,

Strictly conforming applications shall not repeat any of the characters
utility shall permit the repetition of characters, but shall not assign
additional meaning to the repeated characters.
An implementation may define other hold types. The conformance document

they are specified, their internal behavior, and how they affect the
behavior of the utility.

unset or null. (See the Base Definitions volume of POSIX.1-2017,
Section 8.2, Internationalization Variables
the precedence of internationalization variables used to determine the
values of locale categories.)
If set to a non-empty string value, override the values of all the
other internationalization variables.
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).
Determine the locale that should be used to affect the format and
contents of diagnostic messages written to standard error.
Determine the login name of the user.
The standard error shall be used only for diagnostic messages.
The following exit values shall be returned:
An error occurred.
CONSEQUENCES OF ERRORS
In addition to the default behavior, the
utility shall not be required to write a diagnostic message to standard
error when the error reply received from a batch server indicates that
does not exist on the server. Whether or not the
utility waits to output the diagnostic message while attempting to
locate the job on other servers is implementation-defined.
The following sections are informative.

utility does not support any job selection options or wildcard
arguments. Users may acquire a list of jobs selected by attributes

option allows the user to specify the type of hold that is to be
removed. This option allows for USER, SYSTEM, OPERATOR, and
implementation-defined hold types. The batch server that manages the
batch job will verify whether the user is authorized to remove the
specified hold for the batch job. If more than one type of hold has
been placed on the batch job, a user may wish to remove only some of

utility is a new utility vis-a-vis existing practice; it has been
