Updating bash file

Next time I logged in, my GPU box couldn't find nvcc. I panicked - do I need to install CUDA again?? I frantically searched for an answer on the web, and came to a conclusion that I didn't update bash file.

$ gedit ~/.bashrc

Add the following lines at the bottom of the bash file:

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/cuda/extras/CUPTI/lib64"
export CUDA_HOME=/usr/local/cuda

Save and close the text file.
Type the following command to reload the .bashrc file:

$ source ~/.bashrc
