Can't figure out how to find specific characters in specific columns
I am trying to find a specific set of characters in a long file. I only want to find the characters in column 265 for 4 bytes.
Is there a search for that? I tried cut but couldn't get it to work.
Ex. I want to find '9999' in column 265 for 4 bytes. If it is in there, I want it to print out the whole line.
Thanks for any advice.

pod::abstract::filter::find
Pod::Abstract::Filter::find(3pm) User Contributed Perl Documentation Pod::Abstract::Filter::find(3pm)
NAME
Pod::Abstract::Filter::find - paf command to find specific nodes that contain a string.
DESCRIPTION
The intention of this filter is to allow a reduction of large Pod documents to find a specific function or method. You call "paf find
-f=function YourModule", and you get a small subset of nodes matching "function".
For this to work, there has to be some assumptions about Pod structure. I am presuming that find is not useful if it returns anything
higher than a head2, so as long as your module wraps function doco in a head2, head3, head4 or list item, we're fine. If you use head1 then
it won't be useful.
In order to be useful as an end user tool, head1 nodes (...) are added between the found nodes. This stops perldoc from dying with no
documentation. These can be easily stripped using: "$pa->select('/head1')", then hoist and detach, or reparent to other Node types.
A good example of this working as intended is:
paf find select Pod::Abstract::Node
