Operator Environment

For various scripts used by the Operator, the expenv utility is required as are certain environment variables.

Download the expenv utility from its Github Releases page, and place it into your PATH (e.g. $HOME/odev/bin).

The following environment variables are heavily used in the Bash installation procedures and may be used in Operator helper scripts.
