The last line of the file contains a total row count and a checksum:
END|1537451|1328569446
After making other adjustments to the file, I need to strip out the checksum and apply a new value - I have a script to generate the checksum and 'cat' it... (3 Replies)

Hello,
I have a large database with the following structure:

PPI::Token::Comment(3) User Contributed Perl Documentation PPI::Token::Comment(3)NAME
PPI::Token::Comment - A comment in Perl source code
INHERITANCE
PPI::Token::Comment
isa PPI::Token
isa PPI::Element
SYNOPSIS
# This is a PPI::Token::Comment
print "Hello World!"; # So it this
$string =~ s/ foo # This, unfortunately, is not :(
bar
/w;
DESCRIPTION
In PPI, comments are represented by "PPI::Token::Comment" objects.
These come in two flavours, line comment and inline comments.
A "line comment" is a comment that stands on its own line. These comments hold their own newline and whitespace (both leading and trailing)
as part of the one "PPI::Token::Comment" object.
An inline comment is a comment that appears after some code, and continues to the end of the line. This does not include whitespace, and
the terminating newlines is considered a separate PPI::Token::Whitespace token.
This is largely a convenience, simplifying a lot of normal code relating to the common things people do with comments.
Most commonly, it means when you "prune" or "delete" a comment, a line comment disappears taking the entire line with it, and an inline
comment is removed from the inside of the line, allowing the newline to drop back onto the end of the code, as you would expect.
It also means you can move comments around in blocks much more easily.
For now, this is a suitably handy way to do things. However, I do reserve the right to change my mind on this one if it gets dangerously
anachronistic somewhere down the line.
METHODS
Only very limited methods are available, beyond those provided by our parent PPI::Token and PPI::Element classes.
line
The "line" accessor returns true if the "PPI::Token::Comment" is a line comment, or false if it is an inline comment.
SUPPORT
See the support section in the main module.
