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

beepwhenup () { echo 'Enter host you want to ping:'; read PHOST; if [[ "$PHOST" == "" ]]; then exit; fi; while true; do ping -c1 -W2 $PHOST 2>&1 >/dev/null; if [[ "$?" == "0" ]]; then for j in $(seq 1 4); do beep; done; ping -c1 $PHOST; break; fi; done; }
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.

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

@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.
