How do I delete an exported environment variable?
environment-variables, linux, unset
Solution
`unset` is the command you're looking for.
unset GNUPLOT_DRIVER_DIR
Problem
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?
