Depending on how big the uniq output ends up being you might be better using a temporary file. Anything bigger than 4K isn't guaranteed to fit in an argument list on some shells.
without using ls, just using echo so purely pattern matching

change to the new definition.
Color capabilities must be supported by the terminal and initialized using ncurses_start_color(3) prior to calling this function. In addi-

o $r
- A color value, between 0 and 1000, for the red component.
o $g
- A color value, between 0 and 1000, for the green component.
o $b
- A color value, between 0 and 1000, for the blue component.
RETURN VALUES

not have color changing capabilities.
