Hi Reuven:

This is a one-way street. If you could reassign to the variable or unset it, then it wouldn't be read-only :-)

Hi James,

What you mean is that actually you will not be able to set or unset it conditionly, and have to use another var name ?

tnx,
Reuven

>is there a way to unset a variable that was assigned with typeset -r ? As mentioned by JRF, the only way to do this is to exit the shell and start over. Even subshells have magic protection but are easily hacked.
