sendmail $ rules

[slacke]

Hi

I am trying write some rules for sendmail.
I found an example for removing brackets from adress like:

"Fred Thompson <[e-mail]>"

The example rule file (/tmp/testrules) should look like this:

#Add S3 at top of file
S3
R$ *$: < $1 >housekeeping<>
R$+ <$*> <$2>strip excess on left
R<$*> $+ <$1>strip excess on right
R<> $@ <@>MAIL FROM:<>case
R<$+> $: $1 remove housekeeping<>

next it tels me to execute the line:

echo "3 Fred Thompson<[e-mail]>" | sendmail -C/tmp/testrules -d21.12 -bt

But I get different result as it is shown in the example.
I get massage: line3: Inappropriate use of $: on LHS
and
line6: invalid rewrite line ...

I probably have the tabs and spaces wrong in the rules but it's not cleare in the example where to use them.

Can anybody help me pls.
