Which command is used to list all files, including hidden files, in a directory?

• A. ls -a
• B. ls -l
• C. ls -h
• D. ls --all

Answer: (A)

The command that is used to list all files in a directory, including hidden files, is the one that employs the `-a` option with `ls`. In Linux, files that start with a dot (.) are considered hidden files and are not shown by default when using the `ls` command. By adding the `-a` option, you instruct the `ls` command to display all files, including these hidden ones, thus ensuring that you have a complete view of the directory contents. The `-l` option, on the other hand, is used to list files in a long format, providing additional details like permissions, number of links, owner, group, size, and modification date. While it gives a comprehensive view of the listed files, it does not include hidden files unless combined with the `-a` option. The `-h` option stands for human-readable format, which adjusts the file sizes shown (e.g., in KB or MB), but does not affect the inclusion of hidden files. Similarly, the `--all` option is another way to achieve the same effect as `-a`, since it is a longer form of the command that also lists all files, including hidden ones. However, the most
