I found this very cool code to get upload/download speed:
awk '{ if (l1) {
print "↓"($2-l1)/1024"kB/s ","↑"($10-l2)/1024"kB/s"
} else {
l1=$2; l2=$10;
}
}' <(grep wlan0 /proc/net/dev) <(sleep 1; grep wlan0 /proc/net/dev)
However, it returns up to 4 decimals. I rather have no decimals whatsoever. I have previously been able to round numbers using bc or printf, but I seem to only be able to use print
in awk
. What is a good solution to this issue?

%.2f
is a floating point number with two decimal places. Use%.0f
or%i
(integer) to display just the integral part.
