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 of transformed CLI options

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.
--editor	ZOWE_OPT_EDITOR	Define an editor that Zowe CLI uses to open files. The value can be either the editor's executable file location or the name of a program (for example, notepad on Windows or nano on Linux).
