Bug while using terminal zsh #3
Comments
Hello,I also encountered this problem in zsh, and since I'm not good at this part of programming, I was confused about how to modify the script. |
Hi, here is my modified script, which can only support zsh now as I remembered: #!/usr/bin/env bash
# LetMeFly666: this script from https://github.com/phohenecker/switch-cuda
# and changed from ↑

returnIt can also be modified to support both bash and zsh if needed, fell free to @ me. |

Thank you very much for your sharing; it worked effectively after I ran it. Today, I also used the LLM ChatGPT-4o and made modifications suitable for zsh. I tested it, and it worked as well. As for the specific differences between your script and mine, I haven't compared them in detail. I’m sharing this with you, hoping it might provide inspiration or any other form of help. #!/usr/bin/env zsh
set -e
# ensure that the script has been sourced rather than just executed
if [[ "${(%):-%N}" != "$0" ]]; then
echo "Please use 'source' to execute switch-cuda.sh!"
return 1
fi
INSTALL_FOLDER="/usr/local" # the location to look for CUDA installations at
TARGET_VERSION=${1} # the target CUDA version to switch to (if provided)
# if no version to switch to has been provided, then just print all available CUDA installations
if [[ -z ${TARGET_VERSION} ]]; then
echo "The following CUDA installations have been found (in '${INSTALL_FOLDER}'):"
ls -l "${INSTALL_FOLDER}" | egrep -o "cuda-[0-9]+\\.[0-9]+$" | while read -r line; do
echo "* ${line}"
done
set +e
return 0
# otherwise, check whether there is an installation of the requested CUDA version
elif [[ ! -d "${INSTALL_FOLDER}/cuda-${TARGET_VERSION}" ]]; then
echo "No installation of CUDA ${TARGET_VERSION} has been found!"
set +e

# the path of the installation to use
cuda_path="${INSTALL_FOLDER}/cuda-${TARGET_VERSION}"
# filter out those CUDA entries from the PATH that are not needed anymore
path_elements=(${(s/:/)PATH})
new_path="${cuda_path}/bin"
for p in "${path_elements[@]}"; do
if [[ ! ${p} == ${INSTALL_FOLDER}/cuda* ]]; then
new_path="${new_path}:${p}"
fi
done
# filter out those CUDA entries from the LD_LIBRARY_PATH that are not needed anymore

When I use bash, this script will run correctly.
But when I use zsh, the PATH will be misly separated.
Then the terminal will show
prompt_status:5：command not found：wcalways.I think I could make a Pull Request to let the script support both bash and zsh terminal.
Need I to do that? Looking forward to your response.
