Master Linux Like a Pro: Dive into the 2025 RHEL Red Hat Challenge!

The command used to list the contents of a directory in a RHEL Linux environment is the "ls" command. This command is fundamental to Linux and Unix-like operating systems, where it effectively displays the files and directories contained within a specified directory. When invoked, "ls" provides a simple yet informative view of the contents, which can be complemented with various options to customize the output further. For example, using "ls -l" provides detailed information in a long format.

The other options do not align with standard Linux commands. "show" is not a recognized command in RHEL for listing directory contents. The "dir" command is indeed used to list directory contents but is more common in DOS and Windows environments; while it exists in Linux, it is merely an alias for "ls" and is not the primary or preferred command. "list" is not a command in Linux to list directory contents. Understanding these nuances is important for effectively navigating and managing files within a Linux system.
