IP ping bash test

— *ping* … Hello? World?

Check host availability by using ping in bash/shell script command line

#!/bin/sh
 
# -q quiet
# -c nb of pings to perform
 
ping -q -c5 google.com > /dev/null
 
if [ $? -eq 0 ]
then
	echo "ok"
fi

Wait for the “ok” to echo. No echo, no host.

Alternatively, try this:

ping 256.256.256.256 ; echo $?

Viel Glück
