dfits(1) General Commands Manual dfits(1)NAME
dfits - display FITS file header information
SYNOPSIS
dfits [-x xtnum] <list>
dfits [-x xtnum] -
DESCRIPTION
dfits displays FITS header informations on stdout. Header information can be found in the main header only (default), in extensions, or in
both. See the -x option below. dfits accepts multi-file input. 'dfits -' expects single file data coming from stdin. dfits also accepts
now 'HDR' files. These are identified from the fact that they contain a line feed in one of the 80 first characters.
OPTIONS -x xtnum
Specifies the extension to print out. Extensions are numbered starting from 1. If this option is not specified, only the main header
is printed out. If this option specifies an extension that does not exist, nothing is printed out.
Specify 0 as extension number to get a print of the main header plus all extension headers.
Examples :
dfits *.fits
dfits *.fits | grep NAXIS3
gzip -d < star.fits.gz | dfits - | more
dfits -x 0 *.fits
dfits -x 3 *.fits
SEE ALSO
fitsort can be combined with dfits output to sort out keyword values of a group of FITS files.
FILES
Files shall all comply with FITS format
