The go env command in the Go programming language is a tool for managing environment variables related to the Go toolchain. It is part of the Go command-line interface and provides information about the Go environment, such as paths, build configuration, and other settings.

The go env command can be used to obtain information about the Go environment. By default, it prints the values of all Go environment variables. Users can also specify a particular variable to get its value.
Go env supports subcommands for specific tasks. The most commonly used subcommands are:
- go env -w – This subcommand allows users to set a value for a specific environment variable.
- go env -u – This subcommand allows users to unset (delete) a specific environment variable.
