findstr

Findstr is a command line tool available in Windows operating systems that allows users to search for specific strings within text files. It provides an efficient way to find text patterns or specific data within a file or a set of files. Using findstr, users can search for fixed strings, regular expressions, and more complex search patterns. It supports options such as case-sensitive or case-insensitive searches, exact matches, whole word searches, and searching within subdirectories. Findstr has multiple uses, including searching for specific keywords in log files, filtering output from other commands, or locating specific code snippets within a directory of source files. It also provides options to limit search results to specific file types or exclude specific directories. Findstr outputs the matching lines of text, along with the filename and line number, making it easier for users to analyze and locate relevant information.
