You really should add a proper test flag to the if [ $v_flag ] .. as well as putting quotes round the variable as grasper suggests.

Without any arguments the test just checks if the string contains any characters or not. If this is the test you want then write it like:

if [ -n "$v_flag" ]

The reason you have to put quotes round it is because if the string doesn't contain any characters then the command that gets run is

if [ ]

which is illegal. As opposed to

if [ "" ]

Which is what you want to be running.
