I have a list of file names in a text file and what I need to do is check whether the file exists in a directory and/or any of its sub-directories (the parent directory is remote if that makes a difference so I am using a path like '\\computer\share$\parent'<wbr />. If the file exists I want to be able to read the file and look for certain string patterns using regular expressions. This has to be done in Perl but I am a complete novice!<br />
<br />
This process will be running over a huge amount of files so needs to be quite efficient and close any unused resources if there are any... Any ideas?

File Search and contents scan with Perl

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.
