UNIX for Dummies Questions & Answers

Hi

I have read every possible thread here on unix certification.

I was looking for a suggestion as to which is a reasonable certification in terms of price and familiarity in the market.

All the certs mentioned here involve testing in networking,managing users,backups etc which for me is not needed.

I am a junior level oracle developer and therefore i am not looking to be system admin.

My day-to-day tasks involve navigating files and directories,writing and executing shell scripts etc... the basic stuf
I just need a certification that proves that i am familiar with unix commands and shell scripting.

that's all

Please advise
