sed, start af fil navne

Jeg har nogle filer sally-r1, sally-r10, harry-r100, harry-r2

Jeg vil gerne generere en liste hvor de første tegne fra filnavnet 
indtil -r[0-9]+ optræder kun engang.
I ovennævnte eksempel skulle listen i såfald blive

sally
harry

Hvordan gør jeg det. Jeg tror at jeg skal bruge noget lign

ls | sed 's/\(.+\)r[0-9]+/\1/' | sort -u

Men min sed kommando virker ikke som ønsket. Hvad gør jeg galt?
