ping a host until it responds, then play a sound, then exit

After this, just type:

beepwhenup

You need to install "beep" before this would make the beep sound.

Save it in your .profile if you want to use it later

WARNING: this command won't exit until it is successful. You won't be able to CONTROL+C out of it.

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
Mac OSX: ping -oc 30 8.8.4.4 > /dev/null && say "Google name server is up" || say "This host is down"

Audio acknowledgement for host availability.

When running the command from a Linux systems, you can use "festival" or "espeak" instead of "say".

Know a better way?

If you can do better, submit your command here.

What others think

Rather than installing the 'beep' program, on some consoles you can run this for a beep:

echo -en "\x07"

You can achieve this with just ping.

ping -a -c 1

-a is emit audible bell

-c is exit after receiving count replies in this case one

Comment by haplo 266 weeks ago

@haplo: nope. A certain number of pings may be more or less than is needful before you hear a sound. The code presented will only beep when the host finally responds-- not until an arbitrary ping count has been reached.

However you are correct about the "-a" flag to the extent that it "works". It simply does not emit any sound when I use it on my ubuntu workstation.
