| ------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------ |
| `-a` | Displays all files, even hidden ones. Hidden files in Linux are those beginning with `.`. |
| `-i` | Displays inode numbers. |
| `-l` | Displays a vertical list of files with additional information formatted in columns. |
| `-l` | Use a long listing format, that is, each line displays long format information for a file or directory. |

The `ls` command, however, has a lot of options (see `man`):

| Option | Information |
| ------ | ------------ |
| `-d` | Displays information about a directory instead of listing its contents. |
| `-g` | Displays UID and GID rather than owner names. |
| `-h` | Displays file sizes in the most appropriate format (byte, kilobyte, megabyte, gigabyte, ...). `h` stands for Human Readable. |
| `-s` | Displays the number of blocks occupied by the file. One block equals 400K. |
| `-g` | Like -l option, but do not list owner. |
| `-h` | Displays file sizes in the most appropriate format (byte, kilobyte, megabyte, gigabyte, ...). `h` stands for Human Readable. Needs to be used with -l option. |
| `-s` | Displays the allocated size of each file, in blocks. In the GNU/Linux operating system, "block" is the smallest unit of storage in the file system, one block equals 4096Byte. |
| `-A` | Displays all files in the directory except `.` and `..` |
| `-R` | Displays the contents of subdirectories recursively. |
| `-F` | Displays the type of files. Prints a `/` for a directory, `*` for executables, `@` for a symbolic link, and nothing for a text file. |
| `-X` | Sorts files according to their extensions. |
| `-X` | Sorts files according to their extensions. |
