(Freddie)Here is the snippet:
         echo "$2" | sed -e 's/\./\\./g' > /tmp/add_to_proc.tmp
         TEMPFILE=`cat /tmp/sed/add_to_proc.tmp`;

         echo -e "
         # $2 start\r
         :0:\r
         * ^From: .*$TEMPFILE.*\r
         /dev/null\r
         # $2 end\r
         " >> $PROCFILE

         echo "Sucessfully added $2 to $PROCFILE"
         exit 0

This is just for a Linux box, it will not be moved to dos. The "only" 
problem with the ctrl-M is that procmail will not read the file with 
those in there. Like I said, it shows them in vi but not when you cat 
the file.

could you post up your script (or at least the part that does the writing)?

Remove the "\r" bits... The newline that follows each
of them is already embedded in the string which you are
echo-ing, so the file should look like you expect...

Another way to do this that might be slightly
easier than the echo statement would be to
use the "here-document" feature (although
a performance nazi might point out that the
binary for cat takes up slightly more memory
than that for echo):

cat > $PROCFILE <<EOF
# $2 start
...
...
EOF

Re: [Fwd: Re: ctrl-M]

[freddie]

well like some people said, the simple answer is to add for example 
"dos2unix $PROCFILE" to the end of your script. but thats not "elegant", if 
such things matter to you.
the \r is your culprit. that creates a ctrl-m. \n doesnt. im going to 
assume \r is CR/LF and \n is just LF...
i would also shorten the script like the following example, but thats a 
matter of taste of course:
echo "$2" | sed -e 's/\./\\./g' > /tmp/add_to_proc.tmp
TEMPFILE=`cat /tmp/sed/add_to_proc.tmp`;
echo -e "# $2 start\n:0:\n* ^From:.*$TEMPFILE.*\n/dev/null\n# $2 end\n" >> 
$PROCFILE
echo "Sucessfully added $2 to $PROCFILE"
exit 0

   \r will simply generate a ctrl-m ... wherever in the line it is.
If you put it at the end of a line, the implicit \n will get printed
after it (resulting in the well-known cr/lf pair.

\n will generate an extra  LF, but it's not necessary at the end of
a line, because it's implicitly there already.
