Hi there,

through uniq? My routine and habitual cleanup looks something like

      perl -ple 's/^\s+//;s/\s+$//;s/\s+/ /g'|uniq

also toss in something like 's/^(.)\1\1\1+$/\1\1\1/' to reduce fancy

I tried including these two for all messages, that is, without a
condition:

:0 fBw
|perl -ple 's/^\s+//;s/\s+$//;s/\s+/ /g'|uniq

:0 fBw
|perl -ple 's/^(.)\1\1\1+$/\1\1\1/'

Now, my log shows:

procmail: Executing "perl -ple 's/^\s+//;s/\s+$//;s/\s+/ /g'|uniq"
procmail: Executing "perl,-ple,s/^(.)\1\1\1+$/\1\1\1/"

My question is, why are there commas in the second entry ? Do I have
to wonder ? Should I change something ? 

It seems to work well, btw.

Regards,

Sebastian
