Follow-up w/ Perderabo re: mimetool

This is a follow-up re: this thread As I mentioned, this script works very nicely, thanks again. However, the ASCII data of the 'attached file' also shows below the body of the email message. Do you know of a way to 'disable' the attached text from showing? Although the file is attached,...

Perderabo is a UNIX King

This post is here because I couldn't think of putting it anywhere else, and also I imagine it will be deleted since we cannot set this sort of a precedent. However I have to say Perderabo is a UNIX king. I have been a frequent user of these forums for over 2 years (under 2 different names) and...

Sorry Perderabo, really was only asking advice on where best to post, and if I should post. Didn't intend for that missive to be posted.

Perderabo: Is that a common handle?

In an web based turn-based-strategy game I play (which until I am sure of the rules of this section of the forum, I'll not post a link to but is tiny and involves wars, warz even ;)), there is a player called Perderabo who has become rather powerful by the looks of things...

ppmtopgm

ppmtopgm(1)						      General Commands Manual						       ppmtopgm(1)

NAME

       ppmtopgm - convert a portable pixmap into a portable graymap

SYNOPSIS

       ppmtopgm [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as  input.  Produces a portable graymap as output.  The output is a "black and white" rendering of the original
       image, as in a black and white photograph.  The quantization formula used is .299 r + .587 g + .114 b.

       Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any  ppm  program  can
       read  pgm  (and	pbm  ) files automatically.  pgmtoppm is for colorizing a pgm file.  Also, see ppmtorgb3 for a different way of converting
       color to gray.  And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate  the  original
       colors, not necessarily a way that looks like a black and white photograph.

QUOTE

       Cold-hearted orb that rules the night
       Removes the colors from our sight
       Red is gray, and yellow white
       But we decide which is right
       And which is a quantization error.
