    Array help

    I all!!

    I never use array and I'm loosing in documentation..
    I have got this result

    ---start---
    ds0 ds1

    1116577800: 4.9947045401e+0 6 1.8617100885e+0 5
    1116579600: 5.6350684561e+0 6 2.0436081850e+0 5
    1116581400: 5.6629472702e+0 6 2.3664823803e+0 5
    ---end----

    I would like to have only this value:

    $ds0 = 4.9947045401e+0 6
    $ds1 = 1.8617100885e+0 5

    for each line

      How did you generate this result? Code?

          using rrdtool
          RRDtool - The Time Series Database
          https://www.rrdtool.org
          RRDtool is the OpenSource industry standard, high performance data logging and graphing system for time series data. RRDtool can be easily integrated in shell scripts, perl, python, ruby, lua or tcl applications.

              I noticed that Message-ID:

              Use explode() on each line, spitting on the space. The items you need
              will be the second and third elements of the resultant arrays.

                  Hi,

                  This is correct, and I guess about it but I cannot understand how to
                  exclude these 2 initial rows:

                  line1 ds0 ds1
                  line2

                  Cheers
