How do I delete an exported environment variable?

Before installing gnuplot, I set the environment variable GNUPLOT_DRIVER_DIR = /home/gnuplot/build/src. During the installation, something went wrong.

I want to remove the GNUPLOT_DRIVER_DIR environment variable. How can I achieve it?

Solution

  • unset is the command you're looking for.

    unset GNUPLOT_DRIVER_DIR
