info

The "info" command line tool is a documentation browser that provides detailed information about programs, commands, and other topics on Unix-like systems. It is used primarily to access the GNU Project's documentation, which includes information about various software tools and libraries.

The main purpose of "info" is to provide comprehensive and structured documentation in a manageable format. It offers a hierarchical organization of topics, similar to a tree, allowing users to navigate through different levels of details. Each topic within "info" has its own "node" that contains information, examples, and references for that specific topic.

The "info" tool can be invoked by typing "info" followed by the topic name or command you seek information about. Once inside "info," you can use specific key bindings to navigate through different nodes and sections, access links, search for keywords, and more.

In addition to the GNU Project's documentation, some software installed on your system may also have their documentation available in "info" format. This makes "info" a valuable tool for accessing extensive documentation without the need for an internet connection.

Overall, the "info" command line tool provides a comprehensive and structured way to explore and access documentation in Unix-like systems efficiently.
