PMSIGNAL(1)              General Commands Manual             PMSIGNAL(1)

NAME

       pmsignal - send a signal to one or more processes

SYNOPSIS

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

DESCRIPTION

       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 directory 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

       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

       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).
