I have this script:
#!/bin/bash
ping_1=$(ping -c 1 www.test.com | tail -1| awk '{print $4}' | cut -d '/' -f 2 | sed 's/\.[^.]*$//')
ping_2=$(ping -c 1 www.test1.com | tail -1| awk '{print $4}' | cut -d '/' -f 2 | sed 's/\.[^.]*$//')
ping_3=$(ping -c 1 www.test2.com | tail -1| awk '{print $4}' | cut -d '/' -f 2 | sed 's/\.[^.]*$//')
ping_4=$(ping -c 1 www.test3.com | tail -1| awk '{print $4}' | cut -d '/' -f 2 | sed 's/\.[^.]*$//' )
Then I would like to treat the outputs of ping_1-4 in one variable. Something like this:
#!/bin/bash
if [ "$ping_*" -gt 50 ]; then
echo "One ping is to high"
else
echo "The pings are fine"
fi
Is there a possibility in bash to read these variables with some sort of wildcard?
$ping_*
Did nothing for me.
I don't think there's such wildcard. But you could use a loop to iterate over values, for example:
exists_too_high() {
for value; do
if [ "$value" -gt 50 ]; then
return 0
fi
done
return 1
}
if exists_too_high "$ping_1" "$ping_2" "$ping_3" "$ping_4"; then
echo "One ping is to high"
else
echo "The pings are fine"
fi
