Log-File-IP-Sanitizer

Recurses through files in a given directory, and replaces IPv4 Addresses with a pattern of your choosing. You also have the option to specify a string, such as a domain name, to replace.

#IP Sanitizer by Roberto Seldner #Syntax: .\IPSanitize.ps1 .\path
#Use this script to remove IP addresses and a domain from all files within a specified directory and its subdirectories #Script will create a "Sanitized-Logs" directory ONE LEVEL UP from the input folder. All output files will be in this folder.
#Future Change: I will duplicate the input folder, then, rather than redirecting output, I will set-content of the duplicate #folder. This is to preserve the directory structure of the input folder.

#NOTE: I used a simple regex to match IP addresses. It does not validate proper IP formats. #NOTE: I.E. the script would replace a string such as 999.999.999.999 even though that's obviously not an IP Address. #NOTE: I felt there was no need to validate for IPs for my use case since all strings matching this format were IPs/Netmasks.

#KNOWN ISSUES:

1. Directory structure is flattened (as noted above). Consequently, some output files can be overwritten if subdirectories contain same filenames.

2. An empty file is created in the output folder for each directory the script recurses through
