Which command would you use to list all files and directories in the current directory including hidden files?

The command used to list all files and directories in the current directory, including hidden files, is ls -a. In Linux, files and directories that begin with a dot (.) are considered hidden and do not show up in the output of the standard ls command. However, by adding the -a option to ls, you instruct the command to include these hidden files in its output.

The command ls -l is useful for providing detailed information about files and directories, such as permissions, number of links, owner, group, size, and the date and time of last modification, but it does not include hidden files unless used in conjunction with -a (as in ls -la).

The dir command also lists files and directories but does not provide information about hidden files without specific options, and its output format may vary between implementations. The option list -h is not a standard command in Linux and would not be recognized by the system.

Thus, using ls -a is the correct choice for listing all files and directories, including hidden ones.
