stoyanovgeorge / avg_speed.sh
Last active November 3, 2024 19:13
An one line command to get the average RX and TX speed of a particular interface (eth0) over $INT seconds in bytes per second. You need to divide by 128 to get it in Kbps or by 131072 (128*1024) for Mbps.
#!/bin/bash
INT=2; RXDIR=/sys/class/net/eth0/statistics/rx_bytes; TXDIR=/sys/class/net/eth0/statistics/tx_bytes; RXSTART=$(cat $RXDIR); TXSTART=$(cat $TXDIR); sleep $INT; RXEND=$(cat $RXDIR); TXEND=$(cat $TXDIR); RXBPS="$(((RXEND-RXSTART)/INT))"; TXBPS="$(((TXEND-TXSTART)/INT))"; echo "$RXBPS" "$TXBPS"
