Interp: Set GID

[jjzcru]

I know that you can get the PID from the terminal but there is a way to make the process that is going to work with an specificy GID (Group ID)?

Sorry, I don't get what you're trying to do.

Hello there,

I guess I understand the issue. Analog to bash, only UID is provided as environment variable, but not GID.
Other shells like zsh does also export GID.

This issue can be solved with the following patch:
