I agree it is uncommon but the OP stated he didn't want to read the output file for some reason.

If there are valid reasons not to read the file and then not to use the usual and sensible ways suggested elsewhere ("tail -f" or custom equivalent), then Solaris allows to still fulfill the requirement in at least one of these ways. The last two suggestions aren't intrusive to the process creating the log messages.

- patching the code that writes the data (only if source code is available).
- interpose a library that intercept the pattern write
- use a dtrace script to do the same

Of course, my suggestions probably do not make that much sense in this particular case as there are probably no valid reason not to read data appended to the output file. I would however support them should a very fast response time (<1s) is expected.

Eventing is faster and less demanding than polling.

install-solaris(1M)													       install-solaris(1M)

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+

       +-----------------------------+-----------------------------+
       |Interface Stability	     |Evolving			   |
       +-----------------------------+-----------------------------+

       pkginfo(1), install(1M), pkgadd(1M), attributes(5)

       It is advisable to exit install-solaris by means of the exit options in the install-solaris menus.
