PDGREPPE and FGREPPE are two software tools for editing pattern matches in files. PDGREPPE uses Extended Regular Expressions, while FGREPPE uses FIXED literal patterns. Both offer a variety of options to customize searches. Additionally, PDGREPPE allows for the reuse of patterns.

One of the main advantages of Greppes is that it comes in two different versions: PDGREPPE and FGREPPE. PDGREPPE stands for Pattern Definition GREP with Pattern Editing, and it uses an Extended Regular Expression that is similar to EGREP on UNIX systems. This allows you to define complex search patterns and reuse them across different files. In contrast, FGREPPE (Fast or Fixed GREP with Pattern Editing) is more simplified and focuses on searching for fixed patterns only.
Both versions use a Command Line Interface (CLI) that can be customized to suit your needs. You can make changes to the International Text bytes, set up data logging, create custom filter shell commands, and much more. They also come with a variety of features like screen paging, word wrap, recursive file system descent, and multiple drive specifications.
If you need additional support, the online documentation file README.EXE and their website offer detailed information about how to use Greppes to its fullest potential. So if you're looking for a reliable, flexible file editing tool that works on any DOS computer, then Greppes is the way to go.
