How to get only the reply line of a ping test on W

问题:

Usually, when pinging a server IP address we have this in return:

Pinging <IP address> with 32 bytes of data:
Reply from <ip> : bytes=32 time=151 TTL=121
Reply from <ip> : bytes=32 time=151 TTL=121
Reply from <ip> : bytes=32 time=151 TTL=121
Reply from <ip> : bytes=32 time=151 TTL=121

Ping statistics for <IP address>:
packets: sent = 4, Received = 4, lost = 0 (0% loss),
Approximate round trip times in milli-secounds:
Minimum = 151ms, Maximum = 151 ms, Average = 151 ms

How do I get only the following line (only the reply line of one ping test) in return by a simple command in cmd.exe on Windows (whatever Windows language used)?

Reply from <IP address> : bytes=32 time=151 TTL=121

Maybe the simplest way is to display only the second line? How should this be done? Because I don't know how to do it on Windows.

回答1:

This may work more universally.

ping -n 1 <hostname/IP> | FIND "TTL="

回答2:

You can combine findstr command with the skip lines option of for:

C:\>ping 127.0.0.1 | for /f "skip=3 tokens=*" %a in ('findstr Reply') do @echo %a

Output is:

Reply from 127.0.0.1: bytes=32 time<1ms TTL=128

Change %a to %%a if writing a batch file.

回答3:

Well,

ping -n 1 <hostname/IP>

Will send only 1 ping request. And you should be able to find the reply line using none other than the FIND command.

So, something like this:

ping -n 1 <hostname/IP> | FIND "Reply"

UPDATE

I know the above works on an English, Windows 7 machine. I would assume that it would work for other localizations, but this may be an incorrect assumption.

UPDATE 2

This question seems to provide some insight. You may have to write the output of ping to a file (using the > output redirection pipe) and then use the commands in the answers to get only the second line.

It's pretty simple from within batch, but from command line... ugly is major understatement:

(for /f "skip=1 delims=" %F in ('ping -n 1 localhost') do @if not defined _A @echo %F&set _A=0) &set "_A="

But it does the trick, prints second line (whatever it will happen to contain) and skips the rest. You may change line it prints changing skip=.

If you have powershell available, you could simply do: (yes I know it's not how pinging is supposed to be done in PS): powershell "ping -n 1 localhost | select -index 2". You may need to play with index, as on my (XP) laptop ping inserts addtional CR in each line, which has an effect of double - spacing output from PS.

回答5:

You can accomplish this with powershell... here is the code you can add to a script

$ping = new-object System.Net.NetworkInformation.Ping
$reply = $ping.send('127.0.0.1')
if ($reply.status -eq "Success"){
    [string]::Format("Reply from {0},time={1}",$reply.Address.ToString(),$reply.RoundtripTime)
    }else{
    $z = [system.net.dns]::gethostaddresses($hostname)[0].ipaddresstostring
    [string]::Format("FAIL,{0},{1}",$z,"***")
}

You can format the string in any format you want.

Based on @wmz answer,

(for /f "skip=3 tokens=*" %F in ('ping -n 1 <hostname/IP>') do @if not defined _A @echo %F&set _A=0) &set "_A="

is ok as a one-liner not language dependent.
It will also give the result when no response is given (Timeout), where find and findstr will not.
