Dir option

Several optional parameters, when separated from the rest of the command with a dash, can follow the DIR command:

A	display directory information about files with the archive bit on. The archive bit automatically sets to "on" whenever a file is changed. The operating system's back-up utility or the -A option of the COPY command turns it off (see COPY command). This option is completely ignored by Linux systems.
L	display long filenames in addition to the normal DOS style directory. List the permissions for each file on Linux versions.
O	sort the directory output in alphabetical order.
P	pause scrolling after a full screen of information has been displayed. Press <ENTER> for next screen.
W	display names in four columns across the width of the screen. One name per line appears when directory I information is redirected to a file. This option sorts the output and uses the long filename format. -W works like -C, except the sequence of filenames is across instead of down.
U	unadorned - display directory content without the extended filenames
C	print in columnar sorted order with a trailing / symbol for directories and a trailing * for executables.
L	display long filenames in addition to the normal DOS style directory. Show permissions on the left and long filenames on the right.
B	display only the bare long filename, similar to DOS.
