com
test input: a @ bob . com
test returns: bob+|+com . FOUND
Note that here the bob+|+com is a single token.
You can opt to have the original key returned. This is done by specifying the -m database
switch:
Kmatch regex -s2,3 -m -d+|+ -a.FOUND (\
|\)@(\|\).(\|\)
Note that the -m switch overrides the presence of the -s and -d switches:
> test a@bob.com
test input: a @ bob . com
test returns: a @ bob . com . FOUND
23.7.20.3 The -n regex database-map switch
The -n switch inverts the entire sense of the regular expression lookup. It returns a
successful match only if the regular expression does not match. Consider:
Kmatch regex -m -n -a.FOUND (\|\)@(\|\).(\|\)
If you view the effect of this switch in rule-testing mode, you will see that the result is
inverted:
> test a@bob.com
test input: a @ bob . com
test returns: a @ bob . com
> test x@y.net
test input: x @ y . net
test returns: x @ y . net . FOUND
23.7.20.4 The -s regex database-map switch
The -s database-map switchis used withth e regex type to specify a substring to matchand
return. To illustrate, consider the following mini configuration file:
V10
Kmatch regex -s (\|\)
Stest
R $* $@ $(match $1 $)
The regular expression looks to match either the name bob or the name ted, but no other
names.
