Name

gethead - Print FITS or IRAF header keyword values

Synopsis

gethead [-hptv] [-d pathname] [-n num] <FITS or IRAF file> kw1 kw2 ... kwn

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 -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.
