There are two important differences. First, we prepare the text lines to be prependedbeforethe file is locked. Second, instead of creating a new array and copying lines from one array to another, we append the file directly to the@linesarray. ...
Using pack() to extract the required sort key into a consistent string can be an efficient way to build a single string to compare, instead of using multiple sort keys, which makes it possible to use the standard, written in c and fast, perl sort() function on the output, and is the...
