To uninstall and reinstall NVM (Node Version Manager) on Linux, you can follow the steps below:

Uninstall NVM:

   This command will delete the installation directory of NVM and its related files.

3. Open your terminal configuration file (eg  ~/.bashrc, ~/.zshrcetc.).

4. Find and delete lines related to NVM. These lines typically contain statements similar to the following:

   export NVM_DIR="$HOME/.nvm"
   [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
   [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

   Save and close the file after removing these lines.

   This command will download the installation script from NVM's GitHub repository and execute the installation process.

3. Open your terminal configuration file (eg  ~/.bashrc, ~/.zshrcetc.).

4. Check that the configuration file contains NVM related lines. If not, manually add the following to the configuration file:

   export NVM_DIR="$HOME/.nvm"
   [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
   [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
