It will be having 2 values bcoz your infile has two lines of prmAttunityUser..
Code:
$ ret=$(grep "^\$prmAttunityUser=" infile | sed 's/\$//g')
$ echo $ret
prmAttunityUser=ais prmAttunityUser=ais

One more ..
Code:
$ ret=$(nawk '/\$prmAttunityUser=/{sub(/\$/,"");print}' infile)
$ echo $ret
prmAttunityUser=ais prmAttunityUser=ais

papi_get_multiplex

PAPI_get_multiplex(3)						       PAPI						     PAPI_get_multiplex(3)

NAME

       PAPI_get_multiplex -

       Get the multiplexing status of specified event set.

SYNOPSIS

Detailed Description
       C Interface:
	   #include <papi.h>
	    int PAPI_get_multiplex( int  EventSet );

       Fortran Interface:
	   #include fpapi.h
	    PAPIF_get_multiplex( C_INT	EventSet,  C_INT  check )

       Parameters:
	   EventSet an integer handle for a PAPI event set as created by PAPI_create_eventset

       Return values:
	   PAPI_OK
	   PAPI_EINVAL One or more of the arguments is invalid, or the EventSet is already multiplexed.
	   PAPI_ENOEVST The EventSet specified does not exist.
	   PAPI_EISRUN The EventSet is currently counting events.
	   PAPI_ENOMEM Insufficient memory to complete the operation.

       PAPI_get_multiplex tests the state of the PAPI_MULTIPLEXING flag in the specified event set, returning TRUE if a PAPI event set is
       multiplexed, or FALSE if not.

       Example:

	   *   int EventSet = PAPI_NULL;
	   *   int ret;
	   *
	   *   // Create an empty EventSet
	   *   ret = PAPI_create_eventset(&EventSet);
	   *   if (ret != PAPI_OK) handle_error(ret);
	   *
	   *   // Bind it to the CPU component
	   *   ret = PAPI_assign_eventset_component(EventSet, 0);
	   *   if (ret != PAPI_OK) handle_error(ret);
	   *
	   *   // Check  current multiplex status
	   *   ret = PAPI_get_multiplex(EventSet);
	   *   if (ret == TRUE) printf("This event set is ready for multiplexing.")
	   *   if (ret == FALSE) printf("This event set is not enabled for multiplexing.")
	   *   if (ret < 0) handle_error(ret);
	   *
	   *   // Turn on multiplexing
	   *   ret = PAPI_set_multiplex(EventSet);
	   *   if ((ret == PAPI_EINVAL) && (PAPI_get_multiplex(EventSet) == TRUE))
	   *	 printf("This event set already has multiplexing enabled0);
	   *   else if (ret != PAPI_OK) handle_error(ret);
	   *
