NAME

bp-save-history - save bpipe field history

DESCRIPTION

bp-save-history operates on bpipe formatted data streams.

It saves history by transforming scalar fields into one dimensional arrays (stacks), and duplicating the current value of the field onto the stack. If a field is already a one-dimensional array, it does not increase its dimensionality.

Note that if the intrinsic datum stored in a field has non-zero dimensionality, bp-save-history cannot handle it, and will exit with error. It assumes that all one-dimesional arrays are history stacks of zero dimension data.

PARAMETERS

bp-save-history uses an IRAF-compatible parameter interface.

The following parameters are available:

input file

Input ray stream. If the filename is the string stdin, it reads the UNIX standard input stream.

output file

Output ray stream. If the filename is the string stdout, it writes to the UNIX standard output stream.

fields float

A comma separated list of fields to save. If fields is set to %all, all fields are saved.

version boolean

Print out bp-save-history's version and exit.

help boolean

Print out help and exit.
