PMSIGNAL(1)                General Commands Manual               PMSIGNAL(1)

NAME         top

       pmsignal - send a signal to one or more processes

SYNOPSIS         top

       $PCP_BINADM_DIR/pmsignal [-alnp] [-s signal] [PID ...|name ...]

DESCRIPTION         top

       pmsignal provides a cross-platform event signalling mechanism for use
       with tools from the Performance Co-Pilot toolkit.  It can be used to
       send a named signal (only HUP, USR1, TERM, and KILL are accepted) to
       one or more processes.

       The processes are specified directly using PIDs or as program names
       (with either the -a or -p options).  In the all case, the set of all
       running processes is searched for a basename(1) match on name.  In
       the program case, process identifiers are extracted from files in the
       $PCP_RUN_DIR directrory where file names are matched on name.pid.

       The -n option reports the list of process identifiers that would have
       been signalled, but no signals are actually sent.

       If a signal is not specified, then the TERM signal will be sent.  The
       list of supported signals is reported when using the -l option.

       On Linux and UNIX platforms, pmsignal is a simple wrapper around the
       kill(1) command.  On Windows, the is no direct equivalent to this
       mechanism, and so an alternate mechanism has been implemented - this
       is only honoured by PCP tools, however, not all Windows utilities.

OPTIONS         top

       The available command line options are:

       -a, --all
            Send signal to all named processes.

       -l, --list
            List supported signals.

       -n, --dry-run
            List processes that would be affected.

       -p, --program
            Extract programs from PCP runtime PID files.

       -s signal, --signal=signal
            Specify the signal to send, one of: HUP, USR1, TERM, KILL.

       -?, --help
            Display usage message and exit.

PCP ENVIRONMENT         top

       Environment variables with the prefix PCP_ are used to parameterize
       the file and directory names used by PCP.  On each installation, the
       file /etc/pcp.conf contains the local values for these variables.
       The $PCP_CONF variable may be used to specify an alternative
       configuration file, as described in pcp.conf(5).
