To unset that environment variable, you would issue the command unset GO_PATH. This new variable is available system-wide and is inherited by all spawned child processes and shells. Now, if you want to use the path for Go in a script, you could insert $GO_PATH instead of /usr/local/go/bin. SEE: 5 Linux server distributions you should be using (TechRepublic Premium) Issue the command echo $GO_PATH and you’ll see /usr/local/go/bin has been successfully set. To do that, we use the export command as in export GO_PATH=/usr/local/go/bin. First, let’s set GO_PATH as /usr/local/go/bin. You could set and then unset the environment variable. But let’s say you want to do this temporarily. Obviously, you could simply add /usr/local/go/bin to your $PATH, which is the traditional way to solve this problem.
To fix that you have to set an environment variable. But if you just download and unpack Go to /usr/local/go, your system (and the bash shell) will not know those files are there. Most often, those files will be found in /usr/local/go/bin. Because of the way Go is installed, you have to let the system know where the executable binaries are stored. Say, for instance, you install the Go language on Linux. Usually, the name is in UPPER CASE, and the values are, of course, case-sensitive. Each variable contains a name and an associated value. These variables allow you to customize how specific applications and services behave with the system. Simply put, environment variables are a set of dynamic named values stored within the system that is used by applications. The first thing you should know is what environment variables are.
