Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.
$ mySite="superuser"
$ readonly mySite
$ unset mySite
bash: unset: mySite: cannot unset: readonly variable

How can we delete mySite, as it is a readonly variable?

You can't delete mySite. The whole point of the readonly command is to make it final and permanent (until the shell process terminates). If you need to change a variable, don't mark it readonly.

It could be done if you have permission to run gdb (assumed that we are all superuser in here, right? ;)
