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 charac- ters separated by tabs and spaces from its neighbors. +num The first num characters are ignored. Fields are skipped before characters.
