Yes, it could have been:
< filename.gif remsh cray giftoppm '|' ppmtopgm '|' pgmtopbm | pbmto3b1

(it was based on a pipeline using cat in the previous posting,
and was intended as humour (note the smiley)-- the previous
poster asked if there was a way to do the conversion in less than
3 minutes)

Note that I've put the redirection first above; that preserves
the data flow from left to right, which is also evident in the
pipeline using cat.
