OK, then the question is why does catalina.sh write to catalina.out
at all? stdout/stderr of the script would be sufficient. Writing to
a hard wired log file without rotation is the worst option of all
(even if you can choose the file name).

Will this make catalina.out obsolete?

And where would you have the output go when Tomcat is run as a service?  The 
redirection to catalina.out is there not for the benefit of the script, but 
rather to handle sloppily-written webapps that dump things into stdout or 
stderr rather than using a logger.  If you want to eliminate writing to 
catalina.out, set swallowOutput to true in the  elements of the 
offending (and offensive) webapps.

Did you not read his response CHUCK???   He just told you.  I quote:  " 
stdout/stderr of the script would be sufficient"   Not that I have an opinion 
one way or the other.  Just pointing out the obvious.

When you run "bin/catalina.sh start" you are implicitly requesting
your stdout/stderr be redirected. If you don't want that to happen,
don't run it that way.

Try this:

$ bin/catalina.sh start | whatever_you_want

If you use jsvc, catalina.out is not a factor at all. The state of its
obsolescence is up to you.

Nope.

If you use the Tomcat startup scripts, the shell is responsible for
output redirection. Hacking that to pipe-through an external program
(eg. chronolog, etc.) is possible but makes the scripts very complicated
.

If you want to rotate stdout/stderr logs, you should use jsvc or some
other service-runner; they will know how to rotate those files. For
example, jsvc can rotate those files when it receives a signal.

On linux, (system) logrotate ha a “copytruncate” option that could be used.
You’d need to check whether that could lose some log lines though - and if 
you could live with that.
