Awk to print data from current and previous line
Hi guys,

I have found your forum super useful. However, right now I am stuck on a seemingly "simple" thing in AWK. I have two columns of data, the first column in Age (in million years) and the second column is Convergence Rate (in mm/yr).

I am trying to process my data so I can use it to create a step graph of the convergence rate of one continent to another. Here is a sample of my raw input.

105.0 125.2
100.0 128.5
95.0 114.8
90.0 128.1

I want to use awk to get my output to look like this:

105.0 125.2
100.0 125.2
100.0 128.5
95.0 128.5
95.0 114.8
90.0 114.8
90.0 128.1

So I print the first line as is. Then I print the first column from the next record, and the second column from the first line. Then I print both columns from the second line in the raw data, and I repeat that pattern.

I would really REALLY appreciate any help on this. It's really doing my head in - been looking online everywhere but haven't been able to figure it out... Thanks guys :-) If you guys need more info, let me know! Thanks again!

GIT-COLUMN(1)                                                       Git Manual                                                       GIT-COLUMN(1)

NAME

       git-column - Display data in columns

SYNOPSIS

       git column [--command=<name>] [--[raw-]mode=<mode>] [--width=<width>]
                    [--indent=<string>] [--nl=<string>] [--padding=<n>]

DESCRIPTION

       This command formats its input into multiple columns.

OPTIONS

       --command=<name>
           Look up layout mode using configuration variable column.<name> and column.ui.

       --mode=<mode>
           Specify layout mode. See configuration variable column.ui for option syntax.

       --raw-mode=<n>
           Same as --mode but take mode encoded as a number. This is mainly used by other commands that have already parsed layout mode.

       --width=<width>
           Specify the terminal width. By default git column will detect the terminal width, or fall back to 80 if it is unable to do so.

       --indent=<string>
           String to be printed at the beginning of each line.

       --nl=<N>
           String to be printed at the end of each line, including newline character.

       --padding=<N>
           The number of spaces between columns. One space by default.
