Patching WebLogic is necessary but not fun. To help out I have created a simple Bash script for installing CPU/PSU patches.

For information about CPU, PSU and SPU patches check this post.

The script is using BEA Smart Update so it is for WebLogic Server 12.1.1 and older. WebLogic Server 12.1.2 has switched from BSU to OPatch.
