ccdlist image(s)                     gives a short header type list that tells what has been done with ccdproc

hselect @filename $I,exptime yes     showss the exposure times of all images listed in the file
hselect *.fit 1,$I,2 yes outfile     creates a table in an output file with columns of value header '1', name of the file, value header '2'
