DESCRIPTION

       searches for processes having attributes matching the selection criteria specified by its arguments.  The process ID numbers of the matched
       processes are printed, separated by a delimiter, the default being the newline.	Each attribute option can take multiple  values  separated
       by  comma.   will  select those processes that match all the attribute options specified.  If an attribute option has multiple values, then
       the process needs to match one of the values.

       For example:

       matches processes having effective user ID OR AND real group ID OR

       selects processes similar to but instead of printing the process ID numbers, it signals the matched processes.  The user  can  specify  the
       signal to be sent to the matched process as the first argument to By default is assumed.

   Options
       The following options can be used to specify processes to be selected.

       Specifies the signal to be sent to each matched process
		      If  no  signal  is  specified,  is sent by default.  The value of signal follows the same syntax as that of the command; see
		      kill(1).	This option, if specified, should be the first argument to

       Specifies the delimiter to be used while printing the matched entries
		      only).  The default delimiter is a newline.

       Selects processes whose elapsed time matches the time limits specified in
		      timelist.  This time limit can be specified as given below:

		      which will be interpreted as elapsed time than time1 and than time2.  If the argument is only time, then	is  assumed.   The
		      syntax for specifying time is:

		      D:H:m:s

		      for D days, H hours, m minutes and s seconds.  If one of the fields is empty, then 0 is assumed for that field.

		      For example:

		      will be interpreted as elapsed time greater than 300 seconds, and

		      will  be	interpreted  as  elapsed time (greater than 30 minutes and 10 seconds AND less than 2 days, specified by 'el'2) OR
		      (greater than 3 days) OR (less than 10 seconds, specified by 'el'10).

       Perform pattern matching on the entire command line rather than
		      the command name.

       Select processes whose real group ID numbers or group names are given in
		      grouplist.

       Select processes whose process group ID numbers are given in
		      pgrplist.

       Long listing   only).  Print the command name along with the PID.  If used with the option, the command line argument is printed instead of
		      command name.

       Select the most recently created process matching the criteria.
		      This option is mutually exclusive with the option.

       Select the oldest process matching the criteria.
		      This option is mutually exclusive with the option.

       Select processes whose parent process ID numbers are given in
		      ppidlist.

       Select processes belonging to PRM process resource groups whose
		      names or ID numbers are given in prmgrplist.  See

       Selects processes whose current state is given in the
		      statelist.  The values for statelist can be:

		      Running
		      Sleeping
		      Stopped
		      Zombie

       Select processes whose session ID numbers are given in
		      sidlist.

       Select processes associated with the terminals given in
		      termlist.  Terminal identifiers can be specified in one of two forms:

			o  the device's file name (such as or

			o  if the device's file name starts with just the rest of it (such as

		      If  the  device's  file is in a directory other than or the terminal identifier must include the name of the directory under
		      that contains the device file (such as

       Select processes whose real user ID numbers or login names
		      are given in ruserlist.

       Select processes whose real user ID numbers or login names are given in
		      userlist.

       Reverse selection.
		      Select processes that do not meet the matching criteria.

       Perform an exact match of the pattern string.

       Select processes whose processor set IDs are given in
		      psetlist.

       Selects processes whose virtual size matches the size limits specified in
		      sizelist.  The syntax for specifying size limit is as given below:

		      which will be interpreted as virtual size in kilobytes than lowerlimit and than upperlimit.  If the argument is  only  limit
		      then is assumed.

   Operands
       pattern	      Expression (ERE) pattern to match against either the basename or full process argument string.  See regexp(5) for a complete
		      description of the ERE syntax.

EXTERNAL INFLUENCES

   Environment Variables
       If is not specified or is null, it defaults to (see lang(5)).

RETURN VALUE

       and exits with one of the following values:

	      One or more processes matched the criteria.

	      No process matched the criteria.

	      Syntax error in command line.

	      Other errors

EXAMPLES

       Print PID of the cron daemon:

       Send signal to

       Print PIDs of telnet sessions that are active for more than 2 days:

WARNINGS

       Process information can change while or is running; the picture it gives is only a snapshot in time.

       With the option, and matches only up to the initial 1020 bytes of command line with the pattern string.

       and will not match itself.

DEPENDENCIES

   HP Process Resource Manager
       The option require the optional HP Process Resource Manager (PRM) software to be installed and configured.  See prmconfig(1) for a descrip-
       tion of how to configure HP PRM, and prmconf(4) for the definition of

       If HP PRM is not installed and configured and is specified, or fails with error message.

FILES

       Directory of terminal device files.
