Declares which signal is sent to the running 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.
qsig -s KILL 15406
Command Details
The qsig command requests that a signal be sent to executing batch jobs. The signal is sent to the session leader of the job. A signal can only be sent to a job that is in the running state.
Specifying SIGNULL will cause the signal 0 to be sent to the job which will have no effect on the job, but will cause a job obituary to be sent if the job is no longer executing.
