Its too bad that I could not read the manual at the time.. It worked
better when I opened my eyes. ( :=0
So in my test case below, I assigned perl variable $alnum to sec
variable %alnum through the eval. The eval exposed the perl variable
$alnum for later use. Context expressions that follow can use the
values of perl variable $alnum. The leap of faith for me is to treat
(believe) perl variable $alnum and sec variable %alnum the same
depending on whether they were used as action vs pattern, desc, or the
context expression. I suspect that I will have to shadow $alnum as
%alnum now, and stop relying upon $foo to carry me through the perl mini
code. :={
type=Single
desc=Shadow perl and sec alnum variables for time/date
ptype=RegExp
pattern=SEC_(STARTUP|RESTART|SOFTRESTART)
context=[ SEC_INTERNAL_EVENT ]
action=eval %YY ( $YY = `/bin/date +%y` ; chomp($YY); return $YY ; ); \
eval %MM ( $MM = `/bin/date +%m` ; chomp($MM); return $MM ; ); \
eval %DD ( $DD = `/bin/date +%d` ; chomp($DD); return $DD ; ); \
logonly "date %{MM}/%{DD}/%{YY}"
type=Calendar
time=* * * * *
desc=todays date is 10/23/2010.. really
context= =(($MM == 10) && ($DD == 23) && ($YY == 10))
action=logonly "Todays date is %{MM}/%{DD}/%YY"
