A developer is running an application that connects to the Cisco website and collects data.

To set an environmental variable in a Linux system using Bash, the export command is used. This command sets the environment variable for the current session, and any subsequent commands or processes will inherit this environment variable.

For example, to set an environment variable named "website" with the value "cisco.com", you use the following command:

export website="cisco.com"

This sets the variable website and makes it available to any subprocesses started from the shell.
