-F Causes directories to be marked with a trailing ``/'',

executable files to be marked with a trailing ``*'', and

symbolic links to be marked with a trailing ``@'' symbol.

-q Forces printing of non-graphic characters in filenames as the

character ``?''.

-b Forces printing of non-graphic characters in the \ddd

notation, in octal.

-v Causes non-printing characters (with the exception of tabs,

newlines, and form feeds) to be displayed. Control characters

are displayed as ^X (x), where X is the key pressed with

the key (for example, m is displayed as ^M). The

character (octal 0177) is printed as ^?. Non-ASCII

characters (with the high bit set) are printed as -x, where

x is the character specified by the seven low order bits.

-t Causes tabs to be printed as ^I and form feeds as ^L. This

option is ignored if the -v option is not specified.

-e Causes a ``$'' character to be printed at the end of each
line

(prior to the new-line). This option is ignored if the -v

option is not set.

Control assignments

control-character C

Sets control-character to C, where control-character is

erase, kill, intr (interrupt), quit, eof, eol, swtch

(switch), start, stop or susp.

start and stop are available as possible control char-

acters for the control-character C assignment.

If C is preceded by a caret (^) (escaped from the

shell), then the value used is the corresponding con-

trol character (for example, ^D is a d; ^? is

interpreted as DELETE and ^- is interpreted as unde-

fined).
