Ralph Sobek asked,
| What is the best method to eliminate embedded linefeeds?
| Otherwise, how to limit a $MATCH to just a single line?
The second question is much easier to answer than the first. If you had a
multiline match and wanted to strip out the newlines, I can't think of
anything other than feeding the value of $MATCH to tr. But I'm going to read
your post as wanting to strip a trailing newline from a single-line match.
| I currently have conditions like:
|
| * B ?? ()\/\<Foobars?\>
Apparently \> is matching to the newline.
| If "Foobar" is at the end of the line, $MATCH contains a linefeed. Do
| I have to add ".*$" at the end, to limit it to just the considered
| line?
No, that won't help, because "$" will match on the newline.
Suggestion: if your procmail version is new enough to be able to rematch
within a condition (if it isn't, upgrade),
* B ?? ()\/\<Foobars?\>
* MATCH ?? ^^\/.+
"." will match anything except a newline.
If it isn't and you can't upgrade, try Era's suggestion; there is yet another
way, but what Era has posted is better.
