I want to define a global variable. If I do:
the variable is only defined for the current term, not for the terms I'm going to open.
If I do:
it is not better, because my variable is not a classical environment variable like PATH or TERM, but a "personal" one.
I don't want to set the variable in a configuration file like .bashrc, because the variable changes from time to time (it is not the same during the whole session).
Which command do I have to use?
Thanks in advance ++
