Highlights selected text from stdin; lines w/o matches are optionally deleted.
    hilight [-hboruB] [-e] pattern [-e pattern] ... [file ...]

where pattern's are valid sed patterns.
The default highlighting method is to use the "standout" escape sequence.
    
Hilighting Options:
    -b	-- bold hilighting, if available.
    -r	-- reverse-video hilighting, if available.
    -u	-- underline hilighting, if available.
    -B	-- underscore-backspace hilighting: precede each character with _\b.
	   This man page convention is interpreted by "less" to mean underline.
    -o	-- overstrike hilighting: replace each character x with x\bx.
	   This man page convention is interpreted by "less" to mean boldface.

Other Options:
    -e	-- The next word is a pattern.  This is optional before the first
		pattern, but required before the other patterns, else the
		patterns will be interpreted as filenames.  (The name "-e"
		is used by analogy with sed's "-e", although "e" has no
		mnemonic value in "hilight").
    -d  -- delete lines without any hilighted text (default: print all lines).
    -h	-- print this message, then exit.
    -D  -- debug mode (print sed hilighting command before executing).

Note: options must be entered separately; don't run them together.
