Monitor network (data) usage

The amount of data sent(uploaded) & received (downloaded) can be found out using the following bash script.
  • Only works per session, i.e stats are gathered once you power up your PC (or login).
  • Good to have if you have limited data avaiability & want to montior your data usage.
netu() {
# [net]work [u]sage: check network usage stats
​
net_device=$(route | awk '/default/ {print $8}')
TRANSMITTED=$(ifconfig "$net_device" | awk '/TX packets/ {print $6$7}')
RECEIVED=$(ifconfig "$net_device" | awk '/RX packets/ {print $6$7}')
​
pc_uptime=$(uptime -p | awk '{for (i=2; i<NF; i++) printf $i " "; if (NF >= 1) print $NF; }')
printf "%s\n\n" "Network Usage since $pc_uptime"
printf "%s\n" "$(tput bold)🔼 TRANSMITTED $(tput sgr0): $TRANSMITTED"
printf "%s\n" "$(tput bold)🔽 RECEIVED $(tput sgr0): $RECEIVED"
}
