Find Command Syntax

[Drew Tomlinson]

I'm trying to write a script to feed the mail in my spam folder to 
Spamassassin's sa-learn and then delete the mails older than 1 day in 
that spam folder.  Here's my current directory listing:

blacklamb> ll /path/to/Maildir/.Spam/cur
total 70
-rw-------  1 user  group   6118 Sep 22 02:08 
1095844100.98444_0.blacklamb.mykitchentable.net:2,
-rw-------  1 user  group   3545 Sep 22 02:21 
1095844907.98477_0.blacklamb.mykitchentable.net:2,
-rw-------  1 user  group   7408 Sep 22 03:18 
1095848327.99825_0.blacklamb.mykitchentable.net:2,
-rw-------  1 user  group   6560 Sep 22 03:44 
1095849842.99908_0.blacklamb.mykitchentable.net:2,
-rw-------  1 user  group   5203 Sep 22 04:57 
1095854240.48102_0.blacklamb.mykitchentable.net:2,
-rw-------  1 user  group   3313 Sep 22 05:21 
1095855688.48172_0.blacklamb.mykitchentable.net:2,
-rw-------  1 user  group   5718 Sep 22 06:34 
1095860049.48407_0.blacklamb.mykitchentable.net:2,
-rw-------  1 user  group   5254 Sep 22 07:22 
1095862947.48525_0.blacklamb.mykitchentable.net:2,
-rw-r--r--  1 user  group  23314 Sep 21 18:41 
1095863122.M795851P95252V00005B00I0031FB22_1.blacklamb.mykitchentable.net,S=23314:2,S

I'm trying to use the find command to do the deleting but am having 
trouble with the syntax.  For testing, I'm using this command:

blacklamb> find /path/to/Maildir/.Spam/cur \! -newerct 1d -print
blacklamb>

It finds nothing.  I read in the manual that time specifications don't 
have much meaning without the '-' or '+' operator so I try adding it:

blacklamb> find /usr/home/tomlinson_dr/Maildir/.Spam/cur \! -newerct -1d 
-print
find: Can't parse date/time: -1d
blacklamb> find /usr/home/tomlinson_dr/Maildir/.Spam/cur \! -newerct +1d 
-print
find: Can't parse date/time: +1d

I've also tried a combination of adding ()'s around the expression but 
that hasn't worked either.  What am I missing?  Is this an appropriate 
choice for what I want to do?  Is there another command better suited 
for this task?

Thanks,

Drew
