So now I need to solve this one:

Now I have a file like below. I want to take each paragraph between the ">" and

Find the line for which the second and third column is 0. Take the first value.

For example I find 10 0 0 from first paragraph and get the 10.

Then take each line and get the first value and subtract it from 10.

ie

10-10
13-10
16-10
19-10
22-10

If the result is greater than 40 I need to remove the row. Trying to do it in awk.

Do the same for the second section

Find 50 0 0, then take the 50

Subtract first column value from each line in section between ">" from 50. If result greater than 40, remove the row from the file.

etc for all the sections between the ">".

Code:

10 0 0
13 5.92346 5.92346
16 10.3106 10.3106

GIT-STRIPSPACE(1)						    Git Manual							 GIT-STRIPSPACE(1)

NAME
git-stripspace - Remove unnecessary whitespace SYNOPSIS
git stripspace [-s | --strip-comments] < input DESCRIPTION
Clean the input in the manner used by git for text such as commit messages, notes, tags and branch descriptions. With no arguments, this will: o remove trailing whitespace from all lines o collapse multiple consecutive empty lines into one empty line o remove empty lines from the beginning and end of the input o add a missing to the last line if necessary. In the case where the input consists entirely of whitespace characters, no output will be produced. NOTE: This is intended for cleaning metadata, prefer the --whitespace=fix mode of git-apply(1) for correcting whitespace of patches or files in the repository. OPTIONS
-s, --strip-comments Skip and remove all lines starting with #. EXAMPLES
Given the following noisy input with $ indicating the end of a line: |A brief introduction $ | $ |$ |A new paragraph$ |# with a commented-out line $ |explaining lots of stuff.$ |$ |# An old paragraph, also commented-out. $ | $ |The end.$ | $ Use git stripspace with no arguments to obtain: |A brief introduction$ |$ |A new paragraph$ |# with a commented-out line$ |explaining lots of stuff.$ |$ |# An old paragraph, also commented-out.$ |$ |The end.$ Use git stripspace --strip-comments to obtain: |A brief introduction$ |$ |A new paragraph$ |explaining lots of stuff.$ |$ |The end.$ GIT
