DESCRIPTION

    Output format example:

    13:53:21 int: ppp0 recv: [+6270] 5.789.621  tran: [+393] 537.478  rate: 6663 b/s

    Output explanation for each column:

    13:53:21 - time
    int: - short for interface
    ppp0 - interface type
    recv: - marks received bytes start
    [+6270] - received 6270 bytes since last time interval specified as <n>s|m|h|d
    5.789.621 - received 5.789.621 bytes since the interface has been up
    tran: - marks transferred bytes start
    [+393] - transferred 393 bytes since last time interval specified as <n>s|m|h|d
    537.478 - transferred 537.478 bytes since the interface has been up
    rate: - speed in bytes/s of the total traffic
    6663 b/s - 6663 bytes/s

NOTE

    This script relies on the structure of the output generated by kernels 2.2.x and
    2.4.x in /proc/net/dev file.
