UNIQ(1)                 COMMAND REFERENCE                 UNIQ(1)



NAME
     uniq - report repeated lines in a file

SYNOPSIS
     uniq -{u,d,c} [ +n ] [ -n ] [input[output]]

DESCRIPTION
     Uniq reads the input file comparing adjacent lines.  The
     second and succeeding copies of repeated lines are removed;
     the remainder is written on the output file.  Note that
     repeated lines must be adjacent in order to be found. See
     sort(1).  If the -u flag is used, just the lines that are
     not repeated in the original file are output. The -d option
     specifies that one copy of just the repeated lines is to be
     written.  The default output is the union of the -u and -d
     mode outputs.

     The -c option generates an output report in default style
     but with each line preceded by a count of the number of
     times it occurred.

     Only one of the flags u , d , or c can be used at a time.

     The n arguments specify skipping an initial portion of each
     line in the comparison.

OPTIONS
     -c  Generates a default output with each line preceded with
         a count of how many times it occurred.

     -d  Only the first repeated line is output.

     -n  The first n fields together with any blanks before each
         are ignored.  A field is defined as a string of
         nonspace, nontab characters separated by tabs and spaces
         from its neighbors.

     +n  The first n characters are ignored. Fields are skipped
         before characters.

     -u  Repeated lines in the original file are not output.

EXAMPLES
     Typically this command is used on previously sorted files
     like sorted.  In the following example the output is written
     on a new file uniqed:



          uniq sorted uniqed

UNIQ(1)                 COMMAND REFERENCE                 UNIQ(1)



     All lines in the file uniqed will be distinct, since the
     input to uniq was previously sorted.

RETURN VALUE
     [NO_ERRS]      Command completed without error.

     [USAGE]        Incorrect command line syntax. Execution
                    terminated.

     [P_ERR]        A system error occurred. Execution
                    terminated.  See intro(2) for more
                    information on system errors.

CAVEATS
     Lines over 1024 characters in length will be truncated.
