I think eventually humans will wipe each other out through war; Then the Earth would become so polluted that the few survivors will die from radiation/illness/poisoning, etc.
PS: I wish there was an option for zombies.

Hi,
I want to add \n as a EOF at the end of file if it does't exist in a single command. How to do this?
when I use command
echo "1\n" > a.txt
and
od -c a.txt
0000000 1 \n \n
0000003
How does it differentiate \n and eof in this case?

TPING(1) LAM COMMANDS TPING(1)
NAME
tping - Send echo messages to LAM nodes.
SYNTAX
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 wipe(1) (although the use of wipe(1)
is deprecated).
