Hi,

in the input data, I noticed that both either a b c or x y z could be empty.

So I changed the comparison line to:

Code:
echo "${a:=1000}<${x:=1000}" | bc 
echo "${b:=1000}<${y:=1000}" | bc
echo "${c:=1000}<${z:=1000}" | bc

Was hoping that this would do the trick, but when given an input

Code:
22.2
40.8
59.2

36.5
53.7

it returns me
Code:
1
0
1

While it should have been
Code:
1
0
0

.

I am not sure if I understand things right here. Could you please help.

Edit: Fixed the problem, was a mistake with variable names that I was using...Sorry..

tping

TPING(1)                                                           LAM COMMANDS                                                           TPING(1)

NAME

       tping - Send echo messages to LAM nodes.

SYNOPSIS

       tping [-hv] [-c count] [-d delay] [-l length] nodes

OPTIONS

       -h            Print the command help menu.

       -v            Turn OFF verbose mode.

       -c count      Send count messages.

       -d delay      Delay delay seconds between each message.

       -l length     Each message is length bytes long.

DESCRIPTION

       The  tping  command  sends  messages  to,  and  collects replies from, a list of nodes, via the LAM echo server.  It is similar to the UNIX
       ping(8) command, and is used as a quick diagnosis of the LAM network.

       Unless options are specified, tping sends a 1 byte message an infinite number of times, displaying the roundtrip time of each message as it
       completes,  with  a delay of 1 second between roundtrips.  After the loop is broken (with keyboard interrupt, eg: ^C), tping prints statis-
       tics about all roundtrip messages.

EXAMPLES

       tping h
           Echo messages to the local node.

       tping -v n7 -l 1000 -c 10
           Echo 1000 byte messages to node 7.  Stay silent while working.  Stop after 10 roundtrips and report statistics.

BUGS

       There is no built-in timeout and tping will wait forever to receive an echo.  If no echo is received, due to a dead  link  or  node,  tping
       hangs.   Stop  the  process  with  a  keyboard suspend signal (eg: ^Z) and terminate LAM with lamhalt(1) or lamwipe(1) (although the use of
       lamwipe(1) is deprecated).
