Hi,
I have file on Linux with 50000+ lines like below:
Wed Nov 19 04:42:33 2014|1969929|877973|439.549|
Wed Nov 19 04:43:05 2014|1291231|969149|138.522|
Wed Nov 19 04:43:05 2014|969151|969149|5.884|

I need to do the following on Linux:
    First column convert to format "%Y%m%d%H%M%S"
    Second and third column divide by 1048576
    Forth column roundup
