Please merge this fix. Because you don't initialize i variable, script broke, if user have it defined as string (path for example).

Test broken behaviour which pull request fixes:
export i=/tmp/; ./v
./v: line 36: /tmp/: syntax error: operand expected (error token is "/tmp/")
./v: line 43: [: /tmp/: integer expression expected

This fixes cases, when user has $i defined as environment variable.
