"How can I find all the permutations of a list (or a word)"? I have seen this question asked a number of times on forums. There is a module that makes this task very easy: List::Permutor. It is not a core module so you may need to install it. See module for more details: List::Permutor (View Snippet)
You will need to install the Email::Valid module if it's not already installed. See the module documentation for further details.
Email::Valid (View Snippet)
Code snippet to generate random passwords. Avoids using confusing characters such as lower case L (l) and the number one (1), the letter 'O' and the number zero. Upper-case alpha characters could be added to the character set if mixed-case passwords are desired. (View Snippet)
The File::Basename module is used to parse file paths into directory, filename and suffix (or file extension). My simple example shows how to get just the file extensions. (View Snippet)
