The following script enables you to save your mail
to a folder called 19980506 (or whatever today is).
What you can do is when mail arrives you can decide to delete
mailboxes which don't start with:
199805
or
1998050
or 199805
To be selected as old.
Note this script creates a file in /tmp that does the
following:
cat >> 19980506
The mail lines are piped into that command. You
should put the path you want before the 1998
to be sure it goes where you want.
0: "/home/myuser/today"
| awk -F '\012' -f datefiler.awk
You use the END{ part of the awk script to do:
ls -al PATTERN | cut -c 58- | sort | sed 's/^/rm /g' > deljob ;
sh < deljob
The sort command will put them from the oldest
to the newest. You will be deleting the oldest
mailfolders with that command.
PATTERN is the dates you want to delete based
on today's dates.
You need to exclude today's folders.
-- Where datefilter.awk is --
BEGIN{
SHELL = "/bin/ksh"
x = 34
printf("date +%c%%Y%%m%%d%c | sed 's/^/cat \>\> /g' >
/tmp/today",x,x) | SHELL
print "chmod ugo +x /tmp/today | SHELL
}
{
print $1 | "/tmp/today"
}
END{
(delete 10 oldest mailfolders)
}
