Full Discussion: inserting grep -c value into an email subject

Question inserting grep -c value into an email subject
I am profoundly new to *nix, but had a project dropped in my lap that has sparked an interest, leading me here.

I was tasked with daily sending one of our customers a listing of all the spam our filter blocked that was heading for them.
Between Google and I;
I discovered the Server is running Linux version 2.6.11-gentoo-r4.
I learned the basics of grep enough to pare down the amavis.log file to only the pertinent data and figured out how to get it mailed out.
I added a crontab to do this daily, and the job was done to the customer's satisfaction.

Unfortunately, I cannot leave well enough alone, and decided I wanted to have the email subject include the total blocked messages.
grep -c Blocked gives me the total, but I have not been able to track down how to modify the mail subject to reflect this.
I attempted to assign n = grep -c Blocked /var/amavis/amavis.log, but $n just echos as grep.


Pointing out where I'm screwing up or directing me to a link where I can find the info would be greatly appreciated.

AMAVISD-NEW(8)						      System Manager's Manual						    AMAVISD-NEW(8)

NAME

       amavisd-new - Interface between MTA and virus scanner/content filters

SYNOPSIS

       amavisd-new [ -u userid ] [ -g groupid ] [ -c config-file ]...  [ start | stop | reload | debug | debug-sa | foreground ]

DESCRIPTION

       amavisd is a high-performance interface between message transfer agent (MTA) and virus scanners and/or spam scanners.

       This is the amavisd-new incarnation of amavisd.	It is a performance-enhanced and feature-enriched version of the original amavisd program.

       Amavisd-new  works  as  a  SMTP	proxy.	Email is fed to it through SMTP, processed, and fed back to the MTA through a new SMTP connection.
       There is no buffering to disk by amavis, it will report that the transfer was sucessfull only after the forwarding  MTA	has  accepted  the
       message.

       It is possible to use the sendmail milter interface instead of the SMTP proxy method, as well.

OPTIONS

       -c configfile
	      Use  the	specified  configuration  file	instead  of  using  run-parts(8)  to  find  config  files  in /usr/share/amavis/conf.d and
	      /etc/amavis/conf.d (this is a Debian extension to Amavisd-new).  More than one -c option can be specified and the files will be read
	      in the order given.

       -u userid
	      Try to switch to that user id.

       -g groupid
	      Try to switch to that group id.

       start  Starts amavisd-new

       stop   Stops a running amavisd-new

       reload Reloads configuration from config file (may in fact just restart amavisd-new)

       debug  Runs amavisd-new in debug mode

       debug-sa
	      Runs amavisd-new in spamassassin debug mode

       foreground
	      Does not fork to background

FILES

       /etc/amavis/amavisd.conf, /var/lib/amavis, /var/run/amavis/amavisd.pid
