| `-d` | Displays information about a directory instead of listing its contents. |
| `-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. |
| `-s` | Displays the allocated size of each file, in blocks. In the `ls` command, the default size of a single block is 1024-Byte. In the GNU/Linux operating system, "block" is the smallest unit of storage in the file system, and generally speaking, one block is equal to 4096-Byte. In the Windows operating system, taking the NTFS file system as an example, its smallest storage unit is called a "Cluster". The definition of the minimum storage unit name may vary depending on different file systems. |
| `-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. |
