Formatting environment variables

Transform an option into the proper format for a Zowe CLI environment variable, then define a value to the variable. Transform option names according to the following rules:

• Prefix environment variables with ZOWE_OPT_.
• Convert lowercase letters in arguments/options to uppercase letters.
• Convert hyphens in arguments/options to underscores.

Tip: Refer to your operating system documentation for information about how to set and get environment variables. The procedure varies between Windows, Mac, and various versions of Linux.

Examples:

The following table provides examples of CLI options and the corresponding environment variable to which you can define a value:

Command Option	Environment Variable	Use Case
--user	ZOWE_OPT_USER	Define your mainframe username to an environment variable to avoid specifying it on all commands or profiles.
--reject-unauthorized	ZOWE_OPT_REJECT_UNAUTHORIZED	Define a value of true to the --reject-unauthorized flag when you always require the flag and do not want to specify it on all commands or profiles.
