NAME
gethead -- Print FITS or IRAF header keyword values
.ih
USAGE
gethead [-hptv] [-d pathname] [-n num] <FITS or IRAF file> kw1 kw2 ... kwn
.ih
DESCRIPTION
Print values of the specified keywords from the given image header.  By
default they are all listed on one line, separated by spaces.  The
.I \-v
flag causes the keyword names and values to be printed, one keyword per
line.
To read keywords from a list of files, substitute @<listfile> for the
file names on the command line.  To read a lot of keywords, put them,
one per line, in a file and substitute @<keylistfile> on the command line.
If two @ commands are present, the program will figure out which contains
file names and which contains keywords.
