-i      ignore case
-l      the following pattern will highlight the entire line (implies -x)
-m      match case (default)
-o      the following pattern will only match once per line
-x      the following pattern is exclusive
-t      display each file (as a single stream)
-T      display each file (labelling each name)
-r      run program
B       background color attribute (original if absent)
F       foreground color attribute or color name ("foreground.background")
pattern regular expression

When an exclusive pattern matches, no further patterns are tried unless they
exist within a group.
Consecutive format patterns will apply to consecutive lines (up to 8).
The first color is for the match as a whole; the remainder apply to each
captured subpattern (up to 15).  If the first is missing, it will use the
default; any others missing will use the first.  An attribute may be "~" to use
the original value; "!" to invert the original's intensity; or "=" to preserve
the existing color.  The default color is defined by the environment variable
OHL_ATTR; if not set, the foreground intensity of the original color will be
inverted.  Please use "COLOR/?" for attribute values or "//?" for names.
File may contain wildcards, in which case directories, hidden files and
apparent binary files (a zero byte in the first Ki) are silently ignored.
