                  delimit-method={none(default),prepend,separate}  Delimiting   is
                  done with blank lines.
    
           -f, --skip-fields=N
                  avoid comparing the first N fields
    
           -i, --ignore-case
                  ignore differences in case when comparing
    
           -s, --skip-chars=N
                  avoid comparing the first N characters
    
           -u, --unique
                  only print unique lines
    
           -z, --zero-terminated
                  end lines with 0 byte, not newline
    
           -w, --check-chars=N
                  compare no more than N characters in lines
    
           --help display this help and exit
    
           --version
                  output version information and exit
    
           A field is a run of blanks (usually spaces and/or TABs), then non-blank
           characters.  Fields are skipped before chars.
    
           Note: 'uniq' does not detect repeated lines unless they  are  adjacent.
           You  may want to sort the input first, or use 'sort -u' without 'uniq'.
           Also, comparisons honor the rules specified by 'LC_COLLATE'.
           There is NO WARRANTY, to the extent permitted by law.

           The full documentation for uniq is maintained as a Texinfo manual.   If
           the  info  and  uniq  programs are properly installed at your site, the
           command
    
                  info coreutils 'uniq invocation'
    
           should give you access to the complete manual.
