Tools For Managing Patches

There are two utilities for managing patches:

• patchadd - use to install directory-format patches to a Solaris system.

• patchrm - use to remove patches installed on a Solaris system. This command restores the file system to its state before a patch was applied.

Detailed information about how to install and back out a patch is provided in patchadd(1M) and patchrm(1M). Each patch also contains a README file that contains specific information about the patch.

Before installing patches, you might want to know more about patches that have previously been installed. The table below describes commands that provide useful information about patches already installed on a system.
