Regarding number 1, you might be able to do something with this:
mysql> show variables like 'pid%';
+---------------+-----------------------------------------+
| Variable_name | Value |
+---------------+-----------------------------------------+
| pid_file | /var/lib/mysql/tatooine.xyzcorp.com.pid |
+---------------+-----------------------------------------+Regarding number 2 (as well as #1), my inclination is to reach for perl, but I don't know if that's an option for you.

I have 2 unrelated questions:
1) Is there any way to get the hostname that the server is running on from within mysql?
All I can come up with is (pseudo coded):
mysql> system echo insert mysql.hostname `hostname` ... > hostname.sql
mysql> source hostname.sql
Does mysql make it available as a variable somewhere? I have scoured the docs to find nothing obvious.
Note that I am not interested in where I am connected from (select user();).
2) Is there a way to exit an sql script at the top of the script if it turns out that it is running on a slave in a replication scenario?
... something like:
if slave then exit; (followed by more sql)
A 'show slave status' dumps something like a table, but I don't see how to save any of the info in a variable that I might later use in a case statement. Basically, if the results of show slave status aren't zip, I should exit because I am the/a slave.
Thanks for any clues!
