#46 calcmem.sh: invalid use of [ -v

[Kevin Bryan]

In version 38.81 (maybe earlier, but also later versions), this error is generated:

calcmem.sh: line 75: [: -v: unary operator expected

The line in question is:
75 elif [ -v "$EC2_HOME" ]; then

This should be:
75 elif [ -v "EC2_HOME" ]; then

since the -v takes the name of the variable, not the value.

I'm having the same issue with currently latest version (38.90).
