MY QUESTION IS:
What is the purpose of the backslash-slash in the line
* ^Subject: send-ls-list \/[a-z0-9_.-]+@([a-z0-9-]+\.)*com$
---
There is no slash in the subject line of the incoming message, tested by:
UNIX> mail -s "send-ls-listing
anyone(_at_)anydomain(_dot_)anything(_dot_)com" jjg < /dev/null
---
Presumably, the backslash escapes the slash, but, then, what is the
purpose of that slash?
---
This backslash-slash combination is shown in one of the procmailex manpage
examples, but, I don't see an explanation of what the purpose of the
backslash-slash combination is in that manpage example, or in other procmail
manpage (although I may have missed it).
------
I don't see what the backslash-slash is doing in that condition? Do you?
Thanks,
John Gianni
It is the "fencepost operator" that is specific to
procmail. Everything after that on the line is
assigned as a value to the $MATCH variable.
