How to check virtual environments

You can check virtual environments using a simple for loop in your terminal. This command finds all subdirectories in a specified parent folder, assumes each is a virtual environment, and then uses that environment’s pip to check for lifelines.

1. Navigate to the folder that contains all your virtual environments.
2. Run the following command: Bash for venv in */ ; do if [ -f "${venv}bin/pip" ]; then echo "--- Checking in '${venv%?}' ---" ${venv}bin/pip list | grep 'lifelines' fi done

How it works:

• It loops through each subdirectory (e.g., my_project_venv/).
• It checks if a pip executable exists inside the bin folder to confirm it’s likely a venv.
• It then runs the pip list command from within that specific environment and uses grep to filter for the line containing “lifelines”.
• If lifelines is installed, it will print the package name and its version. If not, it will print nothing for that environment.

## For Windows 🪟

You can use a similar loop in either Command Prompt (CMD) or PowerShell.

In PowerShell:

1. Open PowerShell and navigate to the folder containing your virtual environments.
2. Run the following command: PowerShe ll Get-ChildItem -Directory | ForEach-Object { $pipPath = Join-Path $_.FullName "Scripts\pip.exe" if (Test-Path $pipPath) { Write-Host "--- Checking in '$($_.Name)' ---" & $pipPath list | findstr "lifelines" } }

Get-ChildItem -Directory | ForEach-Object {
    $pipPath = Join-Path $_.FullName "Scripts\pip.exe"
    if (Test-Path $pipPath) {
        Write-Host "--- Checking in '$($_.Name)' ---"
        & $pipPath list | findstr "lifelines"
    }
}

Get-ChildItem -Directory | ForEach-Object {
    $pipPath = Join-Path $_.FullName "Scripts\pip.exe"
    if (Test-Path $pipPath) {
        Write-Host "--- Checking in '$($_.Name)' ---"
        & $pipPath list | findstr "lifelines"
    }
}
