qsig - signal pbs batch job
qsig [-s signal] job_identifier ...
command requests that a signal be sent to executing batch jobs.
The signal is sent to the session leader of the job.
If the option is not specified, `SIGTERM'
is sent. The request to signal
a batch job will be rejected if:
- The user is not authorized to signal the job.
- The job is not in the running state.
- The requested signal is not supported by the system upon which the job is
The qsig command sends a Signal Job
batch request to the server which
owns the job.
- -s signal
- Declares which signal is sent to the job.
The argument is either a signal name, e.g. SIGKILL
, the signal name
without the SIG
prefix, e.g. KILL
, or a unsigned signal number,
. The signal name SIGNULL
is allowed; the server will send
the signal 0 to the job which will have no effect on the job, but will cause
an obituary to be sent if the job is no longer executing. Not all signal names
will be recognized by qsig. If it doesn't recognize the signal name, try
issuing the signal number instead.
Two special signal names, "suspend" and "resume", are used
to suspend and resume jobs. Cray systems use the Cray-specific
On non-Cray system, suspend causes a SIGTSTP to be sent to all processes in
job's top task, wait 5 seconds, and then send a SIGSTOP to all processes in
all tasks on all nodes in the job. This differs from TORQUE 2.0.0 which did
not have the ability to propogate signals to sister nodes. Resume sends a
SIGCONT to all processes in all tasks on all nodes.
When suspended, a job continues to occupy system resources but is not executing
and is not charged for walltime. The job will be listed in the "S"
state. Manager or operator privilege is required to suspend or resume a job.
Note that interactive jobs may not resume properly because the top-level shell
will background the suspended child process.
The qsig command accepts one or more operands of the form:
The qsig command will write a diagnostic messages to standard error for each
Upon successful processing of all the operands presented to the qsig command,
the exit status will be a value of zero.
If the qsig command fails to process any operand, the command exits with a value
greater than zero.
