SYNOPSIS

uniq [ -udc [ +-num ] ] [ file ]

-u
Print unique lines.
-d
Print (one copy of) duplicated lines.
-c
Prefix a repetition count and a tab to each output line. Implies -u and -d.
-num
The first num fields together with any blanks before each are ignored. A field is defined as a string of non-space, non-tab characters separated by tabs and spaces from its neighbors.
+num
The first num characters are ignored. Fields are skipped before characters.
