Hi all:
I am running SEC 2.5.2 on Windows XP under cygwin 1.7 with perl
revision 5 version 10 subversion 0 patch 34065 and I have another
little conundrum with SEC.
Using the following ruleset:
# see what $1, $2, $3 evaluate to
type = pair
desc = subpattern test
ptype= regexp
desc2 = test subpattern
pattern = test ([0-9]) ([0-9]) ([0-9])
action = write - "$1, $2, $3, %1, %2, %3"; write - "dollar0: $0"; write -
"pct0: %0"
ptype2 = regexp
pattern2 = test $2
action2 = write - "%1, %2, %3, $1, $2, $3"; write - "dollar0: $0"; write -
"pct0: %0"
with the input:
test 7 8 9
test 8
I expect to see:
Writing event '"7, 8, 9, %1, %2, %3"' to file -
"7, 8, 9, %1, %2, %3"
Writing event '"dollar0: test 7 8 9"' to file -
"dollar0: test 7 8 9"
Writing event '"pct0: %0"' to file -
"pct0: %0"
test 8
Writing event '"7, 8, 9, $1, $2, $3"' to file -
"7, 8, 9, $1, $2, $3"
Writing event '"dollar0: test 8"' to file -
"dollar0: test 8"
Writing event '"pct0: test 7 8 9"' to file -
"pct0: test 7 8 9"
but I actually see:
Writing event '"7, 8, 9, %1, %2, %3"' to file -
"7, 8, 9, %1, %2, %3"
Writing event '"dollar0: test 7 8 9"' to file -
"dollar0: test 7 8 9"
Writing event '"pct0: %0"' to file -
"pct0: %0"
test 8
Writing event '"7, 8, 9, 1, $2, $3"' to file -
"7, 8, 9, 1, $2, $3"
^ huh???
Writing event '"dollar0: test 8"' to file -
"dollar0: test 8"
Writing event '"pct0: test 7 8 9"' to file -
"pct0: test 7 8 9"
Why is $1 being replaced with 1 in the output? IIRC all the $n
variables should be undefined if pattern2 doesn't have any
subpatterns. Also $1 should never have the value of 1 in my senario.
So what command line parameter am I missing this time 8-)?
Maybe -dont_play_games_with_john_he_has_only_had_1_coffee.
If I change pattern2 to capture a subpattern, the captured subpattern
is properly displayed for $1.
Can anybody duplicate this on another platform?
Thanks.
