zfgrep

Zfgrep is a command line tool that stands for "zero-frequency grep." It is a utility used for searching and scanning through plain text files. Unlike regular grep, zfgrep doesn't consider frequency or occurrence of search patterns but instead treats each pattern as unique. This means that it only matches the exact search pattern, allowing for precise searching. Zfgrep is efficient in terms of memory and processing power, making it ideal for large text files. It is particularly useful for finding specific patterns, strings, or lines in log files or other types of text documents. The tool supports regular expressions, allowing for complex search patterns to be specified. Zfgrep provides various options and flags that allow users to customize the search process. It is a part of the GNU grep package, which is widely used in Unix and Unix-like operating systems. Overall, zfgrep is a powerful and lightweight tool for quickly searching text files with precise pattern matching capabilities.
