neud

neud is a command-line utility that allows users to easily search and replace text within files. It provides a simple and efficient way to perform bulk text modifications directly from the terminal. The tool is designed to be user-friendly, offering a straightforward syntax for specifying search patterns and replacement strings.

The primary function of neud is to take a pattern to search for and a string to replace it with, along with a list of files to operate on. It can handle multiple files simultaneously, making it suitable for large-scale text manipulation tasks. The utility typically processes files sequentially, applying the specified replacements.

neud supports regular expressions for pattern matching, allowing for more complex and flexible search criteria. This enables users to target specific text structures rather than just literal strings. The replacement string can also incorporate captured groups from the regular expression, further enhancing its power.

When executed, neud usually provides feedback on the operations performed, indicating which files were modified and how many replacements were made. Some versions may offer options for dry runs, allowing users to preview the changes without actually altering the files. This feature is useful for verifying the correctness of the search pattern and replacement string before committing to the changes. neud aims to be a reliable tool for developers and system administrators who frequently need to manage and modify text content across various files.
