Send ctrl-C signal using bash script.
Code:
declare -a array=( "LLC-load-misses" "LLC-loads" "LLC-store-misses" "LLC-stores" "branch-load-misses" "branch-loads" "dTLB-load-misses" "dTLB-loads" "dTLB-store-misses" "dTLB-stores" "iTLB-load-misses" "iTLB-loads" "branch-instructions" "branch-misses" "bus-cycles" "cache-misses" "cache-references" "cpu-cycles" "instructions" "ref-cycles" "alignment-faults" "context-switches" "cpu-clock" "cpu-migrations" "emulation-faults" "major-faults" "minor-faults" "page-faults" "task-clock" )


arraylength=${#array[@]}
#echo $arraylength
# use for loop to read all values and indexes
for ((i=0; i<${arraylength}-25; i++))
do  
  var1="perf stat --log-fd 3 --repeat 10 -e "
  var2=${array[i]}
  var3=' filebench 3>resultsfilebench' 
  var4=$i
  var5='.log'
  varfinal=$var1$var2$var3$var4$var5
  eval $varfinal
done


When I try to run this script, it opens filebench application and waits for the user to press ctrl-C to iterate through the loop. I want this to be done automatically. perf command first enters the applications waits for the user to press ctrl-C and then print out the results. Is there any way to automate this by iterating through the loop without pressing ctrl-C?

ng_atmllc

NG_ATMLLC(4)						   BSD Kernel Interfaces Manual 					      NG_ATMLLC(4)

NAME

     ng_atmllc -- ATM LLC netgraph node type

SYNOPSIS

     #include <netgraph/ng_atmllc.h>

DESCRIPTION

     The atmllc node type translates frames in to and out of ATM LLC encapsulation, as specified by RFC 1483.  In LLC encapsulation the protocol
     of a given protocol data unit (PDU) is specified by an IEEE 802.2 LLC header, possibly followed by an IEEE 802.1a SubNetwork Attachment Point
     (SNAP) header.  This node currently handles the Ethernet and FDDI protocols.

     The node transmits and receives ATM PDUs on the atm hook.	Received PDUs are decoded and forwarded to the ether or fddi hooks as appropriate.
     Data received on the ether or fddi hooks are assumed to be full Ethernet or FDDI packets as appropriate and are encapsulated into a PDU and
     transmitted via the atm hook.

HOOKS

     This node type supports the following hooks:

     atm     ATM connection.  Typically, this hook would be connected to a ng_atm(4) node, which handles transmission of ATM PDUs over an ATM
	     device.

     ether   Ethernet connection.  This hook sends and receives Ethernet frames.  This would normally be connected to an ng_eiface(4) node if in
	     use.

     fddi    FDDI connection.  This hook sends and receives FDDI frames.

CONTROL MESSAGES

     This node type supports the generic control messages.

SHUTDOWN

     This node shuts down upon receipt of a NGM_SHUTDOWN control message, or when all hooks have been disconnected.
