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...

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.

uniq
UNIQ(1) General Commands Manual UNIQ(1)NAME
uniq - report repeated lines in a file
SYNOPSIS
uniq [ -udc [ +n ] [ -n ] ] [ input [ output ] ]
DESCRIPTION
Uniq reads the input file comparing adjacent lines. In the normal case, the second and succeeding copies of repeated lines are removed;
the remainder is written on the output file. Note that repeated lines must be adjacent in order to be found; see sort(1). If the -u flag
is used, just the lines that are not repeated in the original file are output. The -d option specifies that one copy of just the repeated
lines is to be written. The normal mode output is the union of the -u and -d mode outputs.
The -c option supersedes -u and -d and generates an output report in default style but with each line preceded by a count of the number of
times it occurred.
The n arguments specify skipping an initial portion of each line in the comparison:
-n The first n fields together with any blanks before each are ignored. A field is defined as a string of non-space, non-tab charac-
ters separated by tabs and spaces from its neighbors.
+n The first n characters are ignored. Fields are skipped before characters.
