       Read standard input if FILE is -

       Mandatory arguments to long options are mandatory for short options too.

       -b, --suffix-format=FORMAT
              use sprintf FORMAT instead of %02d

       -f, --prefix=PREFIX
              use PREFIX instead of 'xx'

       -k, --keep-files
              do not remove output files on errors

       --suppress-matched
              suppress the lines matching PATTERN

       -n, --digits=DIGITS
              use specified number of digits instead of 2

       -s, --quiet, --silent
              do not print counts of output file sizes

       -z, --elide-empty-files

       --version

   Each PATTERN may be:
       INTEGER
              copy up to but not including specified line number

       /REGEXP/[OFFSET]
              copy up to but not including a matching line

       %REGEXP%[OFFSET]
              skip to, but not including a matching line

       {INTEGER}
              repeat the previous pattern specified number of times

       {*}    repeat the previous pattern as many times as possible

       A line OFFSET is a required '+' or '-' followed by a positive integer.
