Currently there is no easy way in the Fits program to identically copy multiple keywords from one FITS file/HDU into another file/HDU.

There was a simple example with '--asis' for copying one keyword. But not many. So in Commit d5542488 I just added an example to use '--asis' for many keys.

Further more, I just added an implementation of that example in copy-keys.sh (in my Useful scripts project, for things I haven't yet had time to implement in Gnuastro!).

But this is much easier/faster done inside the FITS program. With this task, I am proposing to add an option like '--keytoout' for this job that is called like below. In that command, the 'KEYA' and 'KEYB' of 'input.fits' will be copied directly into the 'out.fits' (HDU 1).

astfits input.fits --keytoout=KEYA,KEYB --output=out.fits --outhdu=1
