I have a list of phone numbers that I want to use only the last 4 digits as PINs for something I am working on. I have all the numbers in a file but now I want to be removed all items EXCEPT the last 4 digits.
I have seen sed commands and some grep commands but I am having some trouble.
Here is what I want to do.
file(before edit)
Code:
718-555-5465
(718) 555-1234
718-555-5678
file(after edit)
Code:
5465
1234
5678
thanks a lot guys.

Reason: Code tags, please!
sed 's/^..//' file1.txt > file2.txt
this will remove the first two characters of each line of a text file, what sed command will remove the last two characters? This is a similar post to my other....sry if I'm being lazy....
I need a file like this (same as last post)

Hello!
I know that this expression gets rid of non-alphanumeric characters:
sed 's///g'
and I understand that it is replacing them with nothing - hence the '//'-, but I don't understand how it's doing it.
It seems it's finding strings that begin with alphanumeric and replacing them with... (2 Replies)

template::namespace::constants
Template::Namespace::Constants(3) User Contributed Perl Documentation Template::Namespace::Constants(3)NAME
Template::Namespace::Constants - Compile time constant folding
SYNOPSIS
# easy way to define constants
use Template;
my $tt = Template->new({
CONSTANTS => {
pi => 3.14,
e => 2.718,
},
});
# nitty-gritty, hands-dirty way
use Template::Namespace::Constants;
my $tt = Template->new({
NAMESPACE => {
constants => Template::Namespace::Constants->new({
pi => 3.14,
e => 2.718,
},
},
});
DESCRIPTION
The "Template::Namespace::Constants" module implements a namespace handler which is plugged into the "Template::Directive" compiler module.
This then performs compile time constant folding of variables in a particular namespace.
METHODS
new(\%constants)
The new() constructor method creates and returns a reference to a new Template::Namespace::Constants object. This creates an internal
stash to store the constant variable definitions passed as arguments.
my $handler = Template::Namespace::Constants->new({
pi => 3.14,
e => 2.718,
});
ident(@ident)
Method called to resolve a variable identifier into a compiled form. In this case, the method fetches the corresponding constant value
from its internal stash and returns it.
