NAME

       qsig - signal pbs batch job

SYNOPSIS

       qsig [-s signal] job_identifier ...

DESCRIPTION

       The  qsig  command  requests that a signal be sent to executing batch jobs.  The signal is
       sent to the session leader of the job.

       If the -s 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
              executing.

       The qsig command sends a Signal Job batch request to the server which owns the job.

OPTIONS

       -s signal      Declares which signal is sent to the job.

                      The signal argument is either a signal name, e.g.  SIGKILL, the signal name
                      without  the  SIG  prefix,  e.g. KILL, or a unsigned signal number, e.g. 9.
                      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 suspend()/resume() calls.

                      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.

OPERANDS

       The   qsig   command   accepts   one   or   more  job_identifier  operands  of  the  form:
       sequence_number[.server_name][@server]

STANDARD ERROR

       The qsig command will write a  diagnostic  messages  to  standard  error  for  each  error
       occurrence.

EXIT STATUS

       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.
