scope of oracle plsql development /unix shell scripting

I am working in production support in an leading bank and more of my job is more in oracle/plsql. I am learning unix shell scripting and have started development in the same.I would like to know regarding the scope of these two in the industry.Also would like to know about other scripting languages which would be a good combination.

Oracle is considered by many as the most used large database.

As for scripting languages, try to learn the unix shell script first - it is a lifetime learning.

thank u
