extract average time from ping -c

Question

I want to extract from the command ping -c 4 www.stackoverflow.com | tail -1| awk '{print $4}' the average time.

107.921/108.929/110.394/0.905 ms

Output should be: 108.929

Answer 1

One way is to just add a cut to what you have there.

ping -c 4 www.stackoverflow.com | tail -1| awk '{print $4}' | cut -d '/' -f 2

Answer 2

ping -c 4 www.stackoverflow.com | tail -1| awk -F '/' '{print $5}' would work fine.

"-F" option is used to specify the field separator.
