This is a summary of the replies I received on checking if a patch

is instlled under SunOS 4.1.3.

The original request:

The Answer:

If you look at the showrev command it is a shell script, so you can se

what files, etc, it is looking for. For patch information it looks for

files /etc/install/p*. With SunOS 4.1.x you must create these for

yourself manually. In Solaris 2.x this is automated with the

installpatch procedure.

Basic Procedure (Step by Step) To Follow:

a) Run "showrev -p > before"

b) Install a patch

c) Run "showrev -p >after"

d) If new patch doesn't list,

edit a file called "patch" or "patch_anything"

in "/etc/install" and enter a line for the new patch.

e) Write out the file

f) Rerun "showrev -p": The new patch should be documented.

Note: If an entry is made manually, be sure to include the

Revision Number of the patch, as well as the Patch ID Number

itself.
