Hi Gurus,
I've a syslog with thousands of entries as listed below. I need to get
the size for each message. I can do this by awk like:

grep "size=" /var/log/syslog | grep "stat=Delivered" | awk '{print
$13}'

but the issue here is, if the mailbox= paramater doesn't a space in it
will work fine but if it does, then awk '{print $13}' fails to grab
the size= parameter.
e.g. - the first line works fine. - mailbox=!users/hubertp/Trash
but the 2nd doesn't.
mailbox=!users/rachels/Junk E-mail - as it has space inbetween the
name.

Any is greatly appreciated.
TIA
