What command lists all files and folders in the current directory?

The command that lists all files and folders in the current directory is known as "ls." This command is a fundamental part of Unix-like operating systems and is widely used to display the contents of a directory. By executing "ls," users can see the names of files and directories located in the current working directory, along with various options to modify the output, such as including hidden files or displaying detailed information.

"ll" is often actually an alias for "ls -l," which provides a long listing format of files, including permissions, number of links, owner name, owner group, file size, and time of last modification. While "ll" can be used to achieve a similar result, it is not a standalone command universally present across all systems without creating a specific alias.

The command "ps -elf" is used to display currently running processes, providing detailed information about each process rather than listing files or directories. Similarly, "ifconfig" is used for configuring network interfaces and does not pertain to file management at all.

Thus, while the "ll" command can be helpful in some scenarios for a detailed view, "ls" is the primary command for listing files and folders in the current directory.
