              filename [filename ...]

       Print  the  header(s)  of  a FITS file. Optional arguments allow the desired extension(s),
       keyword(s), and output format to be specified. Note that  in  the  case  of  a  compressed
       image, the decompressed header is shown by default.

              path to one or more files; wildcards are supported

   optional arguments:
       -h, --help
              show this help message and exit

       -e HDU, --extension HDU
              specify  the  extension  by name or number; this argument can be repeated to select
              multiple extensions

       -k KEYWORD, --keyword KEYWORD
              specify a keyword; this argument can be repeated to select multiple keywords;  also
              supports wildcards

       -t [FORMAT], --table [FORMAT]
              print  the  header(s)  in  machine-readable  table  format;  the  default format is
              "ascii.fixed_width" (can be "ascii.csv", "ascii.html", "ascii.latex", "fits", etc)

       -c, --compressed
              for compressed image data, show the true header  which  describes  the  compression
              rather than the data
