List contents of directories. If no names are given, list the files in the current directory. With one or more names, list files contained in a directory name or that match a file name. names can include filename metacharacters. The options let you display a variety of information in different formats. The most useful options include -F, -R, -l, and -s. Some options don’t make sense together (e.g., -u and -c).
Print one entry per line of output.
List all files, including the normally hidden files whose names begin with a period.
Display nonprinting characters in octal and alphabetic format.
List files by status change time (not creation/modification time).
Colorize the names of files depending on the type of file. Accepted values for when are never, always, or auto.
Report only on the directory, not its contents.
Print directory contents in exactly the order in which they are stored, without attempting to sort them.
List times in full, rather than use the standard abbreviations.
Long listing like -l, but don’t show file owners.
Print sizes in kilobytes and megabytes.
Print a help message and then exit.
List the inode for each file.
Display filenames without the flags assigned by -p or -f (default).
If file sizes are being listed, print them in kilobytes. ...
