       fmt [-WIDTH] [OPTION]... [FILE]...


       Reformat each paragraph in the FILE(s), writing to standard output.  The option -WIDTH is an abbreviated form of --width=DIGITS.

       -p, --prefix=STRING
              reformat only lines beginning with STRING, reattaching the prefix to reformatted lines

       -s, --split-only
              split long lines, but do not refill

       -t, --tagged-paragraph
              indentation of first line different from second

       -u, --uniform-spacing
              one space between words, two after sentences

       -w, --width=WIDTH
              maximum line width (default of 75 columns)

       -g, --goal=WIDTH
              goal width (default of 93% of width)

       --help display this help and exit

              output version information and exit

       With no FILE, or when FILE is -, read standard input.
