replacekey - replace keywords in a FITS header
SYNOPSIS

DESCRIPTION
replacekey is aimed at replacing keywords in a FITS file's header by new keywords provided by the user on the command-line.

replaces the associated card by the new one (new_keyword=value/comment). If old_keyword is either not found or not provided, associated
card by the new one (new_keyword=value/comment). new_keyword has to be provided.
Examples: You want to change the value of VALUE from 32 to 16 in myfile.fits: % replacekey -k "VALUE" -v "16" myfile.fits
If you want to replace the card with the keyword OLD by "NEW = 3.14 / This is a usefull key" in myfile.fits: % replacekey -k "NEW" -v
"3.14" -c "This is a usefull key" -K "OLD" myfile.fits
If your do not care about the HISTORY cards you have in the header, and want to replace the first one by VALUE=32, you would do:
% replacekey -k "VALUE" -v "32" -K "HISTORY" myfile.fits
