You would use the Tie::File module. The Tie::File documentation should explain it.

Or you could read the file into an array and use an array slice to remove the lines:

open(FH,'file');
@array = <FH>;
close FH;
open(OUT,'>','file');
print OUT @array[4..$#array-2];
close OUT;

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
