What's the better way?

2002-09-22 09:58:16

Inside backquotes:

        BOGOFACTOR="`/usr/local/bin/bogofilter -v 2>/dev/null | tail -1`"
        :0 fhw
        * BOGOFACTOR ?? ().*Spamicity.of.\/[0-9].+
        | formail -A "X-bogofactor: $MATCH

or using chained recipes:

        :0 hbw
        BOGOFACTOR=| (/usr/local/bin/bogofilter -v | tail -1)

        :0 afhw
        * BOGOFACTOR ?? ()Spamicity.of.\/[0-9].+
        | formail -A "X-bogofactor: $MATCH

Or is there any difference at all?

And while we're at it, can someone explain how I parse multiline output
that's been assigned to a variable, so I can skip the `| tail -1`?  I
*thought* that .* should match newlines as well, but it doesn't seem to.

Tnx.  :)
