Here's the command to remove a patch from the Solaris operating system. In the last post, I installed the Sun XVR-100 graphics accelerator patch. For illustration purposes, I'm going to remove it.
#patchrm 114537-40
Check for 114537-40 and it should not be detected #showrev -p | grep 114537-40 or #patchadd -p | grep 114537-40
