The correct answer is: D. ls -a
The ls
command lists the contents of a directory. The -a
option tells ls
to list all files, including hidden files. Hidden files are files whose names start with a dot (.).
The ls -l
command lists the contents of a directory in long format. This includes the file name, permissions, owner, group, size, and modification date.
The ls -x
command lists the contents of a directory in extended format. This includes the file name, permissions, owner, group, size, modification date, and links.
The ls -F
command lists the contents of a directory with a special character for each type of file. For example, directories are listed with a /
, regular files are listed with a -
, and symbolic links are listed with an @
.
None of the above options will list all the hidden files along with the other files.
