countpostln

countpostln is a command-line utility designed for counting lines within files. It offers a straightforward method for determining the number of lines in one or more text files. The program is typically used by developers, system administrators, and anyone who needs to quickly ascertain the size of text-based data.

The primary function of countpostln is to read specified files and output the total number of lines found. It can process multiple files concurrently, providing a combined line count. Advanced options may include filtering capabilities, allowing users to count lines that match specific patterns or exclude certain lines from the count. Some versions might also offer options for case-sensitive matching or regular expression support for more complex filtering scenarios.

The tool is often found in Unix-like operating systems and is a common component of software development toolchains. Its simplicity makes it a valuable addition to scripting and automation tasks where precise line counts are required. For example, it can be used to monitor log file growth or to perform basic analysis on code repositories. The output of countpostln is typically a single integer representing the total line count, making it easy to parse and integrate into other processes.
