How to avoid that extra Enter input

Question

I want to put a command result to my clipboard.Such as my command is echo I love you..Then I execute this in my CMD:

echo I love you.|clip

But actually I will get

I love you.[Enter]

A extra CR character in my clipboard.How to avoid this?Furthermore,can I assign the string "I love you." to a variable a?As I try:

echo I love you.|set a=

will fail to do it.

Maybe I should post two question.But this two question very similar.Any body can help me?I'm in windows 10 now.

Use the set /p prompt to output text without appending cr/lf like echo always does. So:

set /P =I love you<Nul|clip

won't append the cr/lf

Suppose you want to get hostname from this ping output:

> ping -4 -n 1 -a 127.0.0.1

Pinging Matar [127.0.0.1] with 32 bytes of data:
Reply from 127.0.0.1: bytes=32 time<1ms TTL=128

Ping statistics for 127.0.0.1:
    Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

This batch

For /f "tokens=2delims=[ " %%A in (
  'ping -n 1 -a 127.0.0.1^|find "["'
) do Echo %%A

Will return
