Is it possible to run a specific script and receive a message (like msg command) when the pinged machine becomes available?

ping -n <Address> | find "TTL=" && (
msg * Online
)

CodePudding user response：

Here is a PowerShell way:

ping -t <Address> | Select-String 'TTL=' | Select-Object -First 1
msg * Online

• ping -t <Address> repeatedly pings the given host.
• Select-String 'TTL=' searches each output line of ping for the given RegEx pattern. If found, it is piped to the next command.
• Select-Object -First 1 ends the pipeline as soon as the first line has been found.
• This outputs the line containing "TTL=" to the console. If you don't want this, append | Out-Null.
