That works great, cabrao! Thanks a million! Just curious on how to have this output redirected back to the original file, if possible. Or will I have to have this output directed to a new file? I don't want the original file to grow out of control, as it is capturing all logins.

Maybe (if you can not redirect new output into original file) we could parse any lines in original file with a date older than 90 days? Any help is appreciated...

---------- Post updated at 10:03 AM ---------- Previous update was at 09:41 AM ----------

This is the original script to produce output file:

Code:
grep somestring /var/log/messages | awk '{print $1, $2, $9}' | sed -e 's/account=//g' -e 's/@gmail.com//g' -e 's/;//g' -e 's/,...//g' | tr '-' ' '|awk '{print $5" "$2"/"$3"/"$1" "$4}' | sort -o /tmp/testfile1 | uniq

Is there a way to add what cabrao stated to this to minimize the size of my current forever-growing output file (/tmp/testfile1)? All help is greatly appreciated.

moose::meta::typeconstraint::ducktype5.18

Moose::Meta::TypeConstraint::DuckType(3)		User Contributed Perl Documentation		  Moose::Meta::TypeConstraint::DuckType(3)

NAME

       Moose::Meta::TypeConstraint::DuckType - Type constraint for duck typing

VERSION

       version 2.1202

DESCRIPTION

       This class represents type constraints based on an enumerated list of required methods.

INHERITANCE

       "Moose::Meta::TypeConstraint::DuckType" is a subclass of Moose::Meta::TypeConstraint.

METHODS

       Moose::Meta::TypeConstraint::DuckType->new(%options)
	   This creates a new duck type constraint based on the given %options.

	   It takes the same options as its parent, with several exceptions. First, it requires an additional option, "methods". This should be an
	   array reference containing a list of required method names. Second, it automatically sets the parent to the "Object" type.

	   Finally, it ignores any provided "constraint" option. The constraint is generated automatically based on the provided "methods".

       $constraint->methods
	   Returns the array reference of required methods provided to the constructor.

       $constraint->create_child_type
	   This returns a new Moose::Meta::TypeConstraint object with the type as its parent.

	   Note that it does not return a "Moose::Meta::TypeConstraint::DuckType" object!

       See "BUGS" in Moose for details on reporting bugs.
