keyhead \- Change FITS or IRAF header keyword names
sethead [-hknv] <FITS or IRAF file> kw1=kw1a kw2=kwd2a ... kwn=kwdna
Write HISTORY line into output header with
version, current date and time, and names of keywords set.
Write KEYHEAD keyword into output header with the
version, current date and time, and names of keywords whose names are changed.
If a KEYHEAD keyword already exists, move the old value to a
HISTORY line before writing the new value
Write a new file with an added "e" before the extension.
.ls -r letter
Replace value of 1st keyword with value of 2nd keyword instead of changing
the name of the 1st keyword to the 2nd keyword. The 2nd keyword remains in
the header. If the 1st keyword does not exist in the header, it is created.
Print confirmations of each keyword change.
Change the names of keywords in FITS or IRAF image headers. 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.
To change keywords in a list of files, substitute @<listfile> for the file
names on the command line. To change a lot of keywords, put them, one
pair separated by an = sign with no spaces 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. Lines in a keyword list file which do not contain
an = are ignored.
