The basica assumption is that since you've put something on the command
line, it should be what you want 'right now'.  Anything listed on the
command line will _override_ whatever you have in the .conf file.

Right.  Perfect way to do it.

One other thing you can do is to define a 'custom rule type' that includes
both syslog and full alerts.

Side note:  Why don't you log to binary, re-run the binary pcaps thru
snort and have it generate the text files (maybe even syslog stuff) at a
later time.  Only wanting the syslog output for watching/tailing would
stop you from doing that...
