If you read a file to EOF with the inner while, then the outer while loops, the inner file handle is still at EOF. Sequential disk files are like tape drives, and FILE* in C has a redundant command rewind(), which is an fseek to 0 absolute.
Man Page for rewind (opensolaris Section 3) - The UNIX and Linux Forums Of course, R may rewind for you, but that seems a bit too magic.

string::similarity
Similarity(3pm) User Contributed Perl Documentation Similarity(3pm)
NAME
String::Similarity - calculate the similarity of two strings
SYNOPSIS
use String::Similarity;
$similarity = similarity $string1, $string2;
$similarity = similarity $string1, $string2, $limit;
DESCRIPTION
$factor = similarity $string1, $string2, [$limit]
The "similarity"-function calculates the similarity index of its two arguments. A value of 0 means that the strings are entirely
different. A value of 1 means that the strings are identical. Everything else lies between 0 and 1 and describes the amount of
similarity between the strings.
It roughly works by looking at the smallest number of edits to change one string into the other.
You can add an optional argument $limit (default 0) that gives the minimum similarity the two strings must satisfy. "similarity" stops
analyzing the string as soon as the result drops below the given limit, in which case the result will be invalid but lower than the
given $limit. You can use this to speed up the common case of searching for the most similar string from a set by specifying the
maximum similarity found so far.
