pmsignal

PMSIGNAL(1)						      General Commands Manual						       PMSIGNAL(1)

NAME

       pmsignal - send a signal to one or more processes

SYNOPSIS

       $PCP_BINADM_DIR/pmsignal [-a|-l] [-n] [-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 using PID or the
       binary name (with -a option).

       If a signal is not specified, then the TERM signal will be sent.

       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.

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 configura-
       tion file, as described in pcp.conf(5).

       kill(1), killall(1), pcp.conf(5) and pcp.env(5).
