Dear Monks,

As a matter a fact I want to compare lines of texts. E.g. I have file A containing 10..20 lines and I want to search in file B containing 10,000+ lines. Ideally it is also approximated, as text in B may be a little bit different. Invoking an external sub modify or delete text in either or even both texts might be required.

Example:-

File A contains
10:13 process abc encountered a problem
10:14 process abc did a restart

[download]

File B is some trace file.

The sub ignorestuf contains

s/^\d+:\d+//

so that timestamps are removed from A and B while comparing. If both two lines from A are seen in that order in B, there is a match.

The question:-

Is there any module already capable of doing this.

I scan many in CPAN to no avail in the Text::*

Any other pointer to algorithm(s) to ease writing this code.
