Display all files, including hidden files (files starting with .), which are also listed together. This is one of the most commonly used options. | |
Display all files, including hidden files, but excludes the . and .. directories. | |
Only lists the directory itself, not the file data within the directory. | |
#ls will sort by file name by default. Using the -f option will list the results directly without sorting. | |

Display inode node information. | |
Use long format to list file and directory information. | |
UID and GID are displayed instead of the file user name and group name respectively. | |
Output the sorting results in the reverse direction. For example, if the original file names are from small to large, the reverse is from large to small. | |
Listing together with the contents of the subdirectory is equivalent to displaying all files in the directory. | |
Sort by file size, not by file name. | |
Sort by time, not by file name. | |
--color=always --color=auto | never means that the color display is not based on the file characteristics. always means displaying color, ls adopts this method by default. auto means to let the system determine whether to give color based on the configuration. |
