Sure thing. That one liner of code, BTW, is a good test for whether your /bin/bash is vulnerable or not.

Just copy/paste that line at a Bash prompt and hit return. If it prints out:

vulnerable
this is a test

then your Bash has the flaw. OTOH, if it prints out:

bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x'
this is a test

then your Bash is safe from this bug.
