Change FITS and IRAF Image Header Keyword Names

keyhead is a utility for changing FITS or IRAF header keyword names or values. It parses the command line to separate file names from keywords. Files must be legal FITS or IRAF .imh (version 1 or 2) files. Keyword names may be entered in either upper or lower case; they will be automatically translated to upper case by the program. Each current image keyword whose entry is to be modified should be followed by an equal sign and a second keyword, with no intervening spaces. If the -r option is used, the value of the second keyword is transfered to that of the first. Otherwise, the name of the first keyword is changed to the second keyword. A list of filenames may be used by prefacing the name of the file containing the list with a @ or by using a wild card on the command line.
