What does the '/etc' directory typically contain?

The '/etc' directory is a critical part of the Linux filesystem hierarchy, primarily serving as the location for system configuration files. These files control various aspects of the system's behavior and settings. For example, configurations for system services like networking, user accounts, system boot processes, and software applications are typically found in this directory.

Inside '/etc', you'll find files such as 'passwd' for user account information, 'hosts' for hostname resolution, and various configuration files for system services and daemons. The contents are generally plain text files that system administrators can edit to customize their system's behavior.

Temporary files and logs belong to different directories; for instance, logs are commonly found in '/var/log', and temporary files are located in '/tmp'. User applications and tools are usually stored in directories like '/usr/bin' or '/bin'. User-specific data and libraries are typically placed in the user's home directory under '/home' and in locations like '/usr/lib'.

Thus, recognizing that '/etc' is focused on system configuration files is essential for understanding Linux system management and operation. This comprehension aids in effectively navigating and managing a Linux environment.
