.SH DESCRIPTION
.I Qdel
provides a means for a user/operator/manager to delete
one or more jobs. A manager/operator can delete jobs belonging to any
user, while a regular user can only delete his or her own jobs.
If a manager wants to delete another user's job, the manager can specify
the job id. A manager using a job name or pattern
must also specify the user's name via "-u wc_user_list". A 
"qdel wc_job_name" will delete only the jobs of the 
calling user by default.
.I Qdel
deletes jobs in the order in which their job 
identifiers are presented. Find additional information concerning
\fIwc_user_list\fP and \fIwc_job_list\fP in
.M sge_types 5 .
.\"
.\"
.SH OPTIONS
.\"
.IP "\fB\-f\fP"
Force deletion of job(s). The job(s) are deleted from the list of
jobs registered at
.M sge_qmaster 8
even if the
.M sge_execd 8
controlling the job(s) does not respond to the delete request sent by
.M sge_qmaster 8 .
.sp 1
Users who are neither Grid Engine managers nor operators can only use the
.B \-f
option (for their own jobs) if the cluster configuration entry
.B qmaster_params
contains the flag ENABLE_FORCED_QDEL (see
.M sge_conf 5 ).
However, the behavior for administrative and
non-administrative users differs. Jobs are deleted from the Grid Engine
database immediately in the case of administrators. Otherwise, a regular
deletion is attempted first and a forced cancellation is only executed if
the regular deletion was unsuccessful.
.sp 1
Additionally, regular qdel requests can result in a forced deletion of a
job if \fBENABLE_FORCED_QDEL_IF_UNKNOWN\fP is set in the \fBqmaster_params\fP
(see 
.M sge_conf 5 ).
.\"
.IP "\fB\-help\fP"
Prints a listing of all options.
.\"
.IP "\fB\-t\fP"
Deletes specified tasks of an array job. It means tasks created
by the \fIqsub \-t\fP command. For example, after creating an array
job with the command
"qsub \-t 1\-100 $SGE_ROOT/examples/sleeper.sh" it is possible to
delete tasks 5\-10 from the job array with the command "qdel job_id \-t 5\-10".
All other tasks (1\-4 and 11\-100) will be executed.
.\"
.IP "\fB\-u wc_user_list\fP"
Deletes only those jobs which were submitted by
users specified in the list of usernames.
For managers it is possible to use \fB\qdel -u "*"\fP to delete
all jobs of all users. If a manager wants to delete a specific
job of a user, he has to specify the user and the job. If no 
job is specified, all jobs from that user are deleted.
.\"
.IP "\fBwc_job_range_list\fP"
A list of jobs which should be deleted.
.\"
.\"
.SH "ENVIRONMENT VARIABLES"
.\" 
.IP "\fBSGE_ROOT\fP" 1.5i
Specifies the location of the Grid Engine standard configuration
files.
.\"
.IP "\fBSGE_CELL\fP" 1.5i
If set, specifies the default Grid Engine cell. To address a Grid Engine
cell
.I qdel
uses (in the order of precedence):
.sp 1
.RS
.RS
The name of the cell specified in the environment 
variable SGE_CELL, if it is set.
.sp 1
The name of the default cell, i.e. \fBdefault\fP.
.sp 1
.RE
.RE
.\"
.IP "\fBSGE_DEBUG_LEVEL\fP" 1.5i
If set, specifies that debug information
should be written to stderr. In addition the level of
detail in which debug information is generated is defined.
.\"
.IP "\fBSGE_QMASTER_PORT\fP" 1.5i
If set, specifies the tcp port on which
.M sge_qmaster 8
is expected to listen for communication requests.
Most installations will use a services map entry for the
service "sge_qmaster" instead to define that port.
