HOW TO CHECK FOR VULNERABLE SHELL

*HOW TO CHECK FOR VULNERABLE SHELL*
To determine if a Linux or Unix system is vulnerable, run the following command lines in your linux shell:

     * env X="() { :;} ; echo shellshock" /bin/sh -c "echo completed"
     * env X="() { :;} ; echo shellshock" `which bash` -c "echo completed"

If you see the words "/shellshock/" in the output, errrrr… then you are at risk.
