I can get total network usage from terminal by ifconfig wlp0s20f3 but i also get many other extra info about wlp0s20f3 device.

The output:

wlp0s20f3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500

        inet 192.168.43.67  netmask 255.255.255.0  broadcast 192.168.43.255

        inet6 fe80::5f55:a45c:b66a:a7d2  prefixlen 64  scopeid 0x20<link>

        ether 48:f1:7f:f3:15:83  txqueuelen 1000  (Ethernet)

        RX packets 82724  bytes 108476705 (103.4 MiB)

        RX errors 0  dropped 0  overruns 0  frame 0

        TX packets 28959  bytes 3840172 (3.6 MiB)

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

I only need 103.4 MiB for rx and 3.6 MiB for tx to use together with command output plasmoid in kde panel. How can i get that?

PS: Any bash script to parse ifconfig output or any application gives that values are acceptable

The more obvious route is to use Grep to extract only the values.

# RX bytes

ifconfig wlp0s20f3 | grep -o '[0-9.]* MiB' | head -n1

# TX bytes

ifconfig wlp0s20f3 | grep -o '[0-9.]* MiB' | tail -n1

A more elegant alternative is to fetch the values (in bytes) from the /sys/class/net/wlp0s20f3/statistics/ directory.
```
cat /sys/class/net/wlp0s20f3/statistics/rx_bytes

cat /sys/class/net/wlp0s20f3/statistics/tx_bytes
```
