Which command would you use to list files in the current directory?

The command that is commonly used to list files in the current directory is 'ls'. This command is a staple of Unix-based systems and is recognized for its efficiency in displaying the contents of directories. When executed, 'ls' provides a list of files and subdirectories, typically showing their names, and can be modified with various options to display additional information such as file permissions, ownership, size, and modification date.

While 'dir' can also be used for listing files in some Unix-based systems and is more prominent in DOS/Windows environments, it is not as widely recognized as 'ls' in the Linux community. 'list' and 'show' are not standard commands for listing files in a Linux environment; therefore, they do not serve the intended purpose of the question effectively. Familiarity with 'ls' and its options is essential for anyone working in Linux, as it is a fundamental command for navigating and interacting with the file system.
