NAME

       uniq - report repeated lines in a file

SYNOPSIS

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

DESCRIPTION

       Uniq  copies  the  input  file,  or  the standard input, to the standard output, comparing
       adjacent lines.  In the normal case, the second and succeeding copies  of  repeated  lines
       are removed.  Repeated lines must be adjacent in order to be found.

       -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.

BUGS

       Field selection and comparison should be compatible with sort(1).
