Okay, but I don't see a need to run `date` twice in your

use to call procomail in your .forward or on your system.
Sure, I COULD finagle around with getting the date some other way,
but there were a variety of reason why rewriting the FROM_ header or
getting the date from the FROM_ header was not acceptable to me at
the time I first wrote these recipes (a lot of mail I was processing
was archived email that was being resorted under a new server.
`date` is cheap and I have no issues with calling it, even twice.
And yeah, I know, I could just call it once and then set the two
dates from there. But sometimes ease of reading is an advantage.
For example, I have code similar to yours for 'fixing' dates in the
FROM_ headers that where munged by Eudora. In fact, you probably
wrote a healthy percentage of that code three or four years back..
But which is more readable, the 20 lines you have or
DATE=`date '+%d-%b-%Y'`
LONGDATE=`date "+%y-%b-%d %I:%M:%S %z"`
?
I don't need 20 lines. It's an INCLUDERC.
INCLUDERC = $SUBS/datecheck
And I haven't had to look at it in years.
The thing is, I need and want those values anyway. If I ran /bin/date,
I'd still want to create all those vars for the stuff I do.
Another approach, that, so far as I know, David Tamkin was first to
post about circa seven or nine years ago, was to generate a file
daily, e.g., with cron. I did that for a number of years as well.
The file had in it, e.g.,
MYDATE = 02-Jun-2007
Now it can be read in with an INCLUDERC and doesn't require a
call to date with every single email. If you're processing old
mail, you could do that.
You could also have a test to compare the From_ date against
that read-in MYDATE and only bother to run /bin/date to get your
timestamp if the two are different; otherwise assume the message
timestamp is to be used.
If you are processing new mail, the timestamp in the From_ will
be sufficient for a log entry. If you are processing old mail,
you may not *want* the timestamp in the log entry anyway. So
use a different rcfile and do it differently.
