	sponge
 n.

    [Unix] A special case of a filter that reads its entire input before
    writing any output; the canonical example is a sort utility. Unlike most
    filters, a sponge can conveniently overwrite the input file with the output
    data stream. If a file system has versioning (as ITS did and VMS does now)
    the sponge/filter distinction loses its usefulness, because directing
    filter output would just write a new version. See also slurp.
