gethead
gethead(1) General Commands Manual gethead(1)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 @<list-
file> 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.
Options-a List file name even if keywords are not found
-d Root directory for input files (default is cwd)
-e Output keyword=value's on one line per file
-f Never print filenames (default is to print them if more than one)
-g Output keyword=value's on one line per keyword
-h flag causes the keyword names to be printed at top of columns.
-n Number of decimal places in numeric output
-o OR conditions instead of ANDing them
-p Print full pathnames of files
-t flag causes the output to be in tab-separated tables with keyword column headings.
-u Always print ___ if keyword not found, event if only one keyword in search
-v Print output as <keyword>=<value>, one per line
