                     12: uniq reads  input line  by line from  infile and writes  all non-
                     13: duplicated  lines to  outfile.  The  input  file must  be sorted.
                     14: uniq uses  the standard input or output if  either infile or out-
                     15: file is omitted.  The following describes the available options:
                     16: 
                     17: -cc    Print each  line once,  discarding duplicate  lines; before
                     18:      each line,  print the number of times  it appears within the
                     19:      file.
                     20: 
                     21: -dd   Print only lines  that are duplicated within the file; print
                     22:      each line only once; do not print any counts.
                     23: 
                     24: -uu   Print only lines that are _n_o_t duplicated within the file.
                     25: 
                     26: uniq by default  behaves as if both -uu and  -dd were specified, so
                     27: it prints each unique line once.
                     28: 
                     29: Optional specifiers  allow uniq to  skip leading portions  of the
                     30: input lines when comparing for uniqueness.
                     31: 
                     32: -_n   Skip n fields of each  input line, where a field is any num-
                     33:      ber of  non-white space characters surrounded  by any number
                     34:      of white space characters (blank or tab).
                     35: 
                     36: +_n   Skip n characters  in each input line, after skipping fields
                     37:      as above.
