What command is used to display environment variables settings?

The command that is typically used to display environment variable settings is the one that shows the current locale settings, among other information related to local environment variables. This command provides details about categories such as character encoding, language, and regional settings, which are all part of the broader environmental context in which processes execute.

While other commands also play a role in managing or displaying environment variables, they do not specifically target the complete set of environment variables in the same comprehensive manner. For example, one command lists all shell variables, including non-environment variables, which might not be relevant if you're purely looking for environmental settings. Another command focuses on exporting variables to subshells rather than listing the current environment settings.

Hence, using the command that centers around the locale gives you a snapshot of the critical environment configurations, making it valuable for understanding how processes will behave in relation to system culture and language settings.
