## Advanced Installation Commands
### Install Node.js from Source
For developers needing a specific setup or patch:
```
nvm install -s <node_version>
```
### Reinstall Packages When Installing a New Version
Easily transfer global packages to the newly installed version:
```
nvm install <node_version> --reinstall-packages-from=current
```
### Install Multiple Versions Simultaneously
Batch install several versions at once:
```
nvm install <node_version_1> <node_version_2> <node_version_3>
```
## Efficient Node Version Switching
### Switching with Environment Variables
Automatically switch Node.js versions based on your project’s configuration:
```
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
nvm use
```
By adding a .nvmrc file in your project directory containing the desired Node.js version, NVM will switch versions automatically when you navigate to the project.

### Persistent Node.js Version Across Terminals
Ensure consistency across different terminal sessions:
```
nvm alias default <node_version>

```
## Enhanced Listing and Filtering
### List All Installed Versions with Detailed Info
See comprehensive details about installed Node.js versions:
```
nvm ls
```
### Filter Installed Versions
Quickly locate specific versions:
```
nvm ls | grep <filter>

```
### List All Available Versions and Highlight Specifics
For in-depth searching:
```
nvm ls-remote --lts       # Lists all LTS versions
nvm ls-remote | grep "v14" # List all v14.x versions

```
## Managing Global Packages
### List and Migrate Global Packages
Identify and migrate global packages to another Node.js version:
```
nvm list global           # Lists globally installed packages for the current version
nvm reinstall-packages <node_version>  # Reinstall global packages from a specific version

```
### Removing Outdated Global Packages
Clean up outdated packages:
```
npm uninstall -g <package_name>

```
## Leveraging Aliases
### Creating Custom Aliases
Define custom aliases for frequent version switches:
```
nvm alias myproject <node_version>
```

### Updating and Deleting Aliases
Modify or remove aliases as your projects evolve:

```
nvm alias <alias_name> <new_node_version>
nvm unalias <alias_name>
```

## Path and Version Verification
### Locate Executables
Quickly find where specific versions are installed:
```
nvm which <node_version>
```
### Verify Multiple Versions Simultaneously
Check installed versions of Node, NPM, and NVM:

```
node -v && npm -v && nvm -v

```
## Cleaning Up
### Removing Old or Unused Versions
Free up space by uninstalling unnecessary versions:

```
nvm uninstall <node_version>
```

### Automate Version Removal
Automate cleanup based on a condition or date:
```
nvm ls | grep -E "v[0-9]+\.[0-9]+\.[0-9]+" | xargs -I {} nvm uninstall {}

```
## Troubleshooting
### Resolving Common Issues
Identify and fix common NVM problems:

```
nvm debug

```

### Resetting NVM Environment
If things go awry, reset your NVM setup:
```
rm -rf ~/.nvm
git clone https://github.com/nvm-sh/nvm.git ~/.nvm
cd ~/.nvm
git checkout git describe --abbrev=0 --tags
. nvm.sh

```

By mastering these advanced NVM commands, you'll enhance your Node.js development experience, ensuring optimal performance and flexibility. Dive deeper, experiment, and watch your productivity soar!
