Ultimately, what I really want to do anyway is a startup sequence

webapps the list of which I store in another place. The deploy command
only returns after the app is fully deployed, which is good (and so
does the undeploy command).
[...]
Third, what if you want to do SNMP monitoring
(-Dcom.sun.management.snmp.port=xxx etc etc)? You can't with the
bundled scripts. Why? If you set JAVA_OPTS appropriately, these
JAVA_OPTS will also be used for shutdown... Which means you can't
shutdown at all: EADDRINUSE. Unless you arrange for different
JAVA_OPTS on startup and shutdown, which I don't need to do with my
scripts.
As Chuck suggests, you haven't read the documentation well enough
because catalina.sh has options to cover your situation described above.
Indeed.

Ultimately, what I really want to do anyway is a startup sequence
which starts Tomcat up only with the manager app,
MGA default Tomcat installation includes the manager. To add an instance of the
MGManager web application Context to a new host install the
MGmanager.xml context configuration file in the
MG$CATALINA_BASE/conf/[enginename]/[hostname] folder. Here is an example:
MG
Context path=/manager debug=0 privileged=true
docBase=/usr/local/kinetic/tomcat6/server/webapps/manager
/Context
MG
and which deploys
webapps the list of which I store in another place. The deploy command
only returns after the app is fully deployed, which is good (and so
does the undeploy command).
MGhttp://mojo.codehaus.org/tomcat-maven-plugin/deployment.html
MGtomcat-maven-plugin supports the following configuration attributes
MGconfigurable war file folder called warSourceDirectory
MGconfigurable location for context.xml called contextFile
MG running embedded tomcat from maven with command
MGmvn tomcat:run

I'm interested to see how you are able to launch Tomcat and have your script continue only after all webapps have been deployed. If you can already do that, you can just call catalina.sh and perform the same stalling technique after it completes. The same can be said for shutdown. Your command line is not significantly different from that which catalina.sh uses. Second, I use Linux only and don't need the cygwin/as400/etc specific stuff. While that may be true, the startup scripts are often tweaked for several reasons and you will likely want to get those updates.
