        "content": "Yes \u2014 in PowerShell (including aliases like `ls`, `dir`, `gci`) you *can* get a directory listing that shows *only filenames*. Here are some ways to do that:\n\n---\n\n## Basic commands\n\n1. **`Get-ChildItem -Name`**\n\n   This is the most straightforward way. It returns just the file and folder names (as strings), without extra properties.  \n   ```powershell\n   Get-ChildItem -Name\n   ```\n   You can also alias this:  \n   ```powershell\n   ls -Name\n   ```\n\n2. **With filtering for only files (optional):**\n\n   If you want only files (no folders), combine `-File` with `-Name`:\n\n   ```powershell\n   Get-ChildItem -File -Name\n   ```\n\n---\n\n## More formatting options\n\n- **`Select-Object -ExpandProperty Name`**  \n  If you use full `Get-ChildItem` output (which returns objects with properties like `Name`, `FullName`, etc.), you can pull out just the `Name`:\n\n  ```powershell\n  Get-ChildItem | Select-Object -ExpandProperty Name\n  ```\n\n- **Getting only files, and maybe sorting:**\n\n  ```powershell\n  Get-ChildItem -File | Sort-Object Name | Select-Object -ExpandProperty Name\n  ```\n\n---\n\n## Examples with recursion or directory paths\n\n- **List all filenames in current directory and subdirectories:**\n\n  ```powershell\n  Get-ChildItem -File -Recurse -Name\n  ```\n\n- **List filenames in a specific path:**\n\n  ```powershell\n  Get-ChildItem -Path \"C:\\MyFolder\" -File -Name\n  ```\n\n---\n\n## Comparison to CMD\n\nIf you\u2019re more familiar with the CMD prompt, the `dir` command has a similar \u201cbare\u201d mode:\n\n```cmd\ndir /b\n```\n\nThat shows just the filenames. PowerShell can also invoke CMD directly, but using `Get-ChildItem` is usually more powerful and flexible. ([ss64.com](https://ss64.com/nt/dir.html?utm_source=openai))\n\n---\n\nIf you want, I can also show you how to get *just the base name* (without extensions), or full paths, etc. Do you want those variations?"

        "content": "To enable script execution in PowerShell, you need to modify the *execution policy*. By default it\u2019s usually set to **Restricted**, which prevents `.ps1` scripts from running. ([oreilly.com](https://www.oreilly.com/library/view/professional-windows-r-powershell/9780471946939/9780471946939_enabling_scripts_on_your_machine.html?utm_source=openai))\n\nHere\u2019s how you can check, change, and understand execution policies.\n\n---\n\n## Checking the current policy\n\nOpen PowerShell and run:\n\n```powershell\nGet-ExecutionPolicy\n```\n\nTo see policies defined at all scopes (machine, user, process, etc.):\n\n```powershell\nGet-ExecutionPolicy -List\n```\n\nThese will show you what policies are set where. ([makeuseof.com](https://www.makeuseof.com/enable-script-execution-policy-windows-powershell/?utm_source=openai))\n\n---\n\n## Common execution policy levels\n\nHere are some policy options you can set:\n\n- **Restricted** \u2014 Doesn\u2019t allow any script to run. This is the default on Windows client systems. ([oreilly.com](https://www.oreilly.com/library/view/professional-windows-r-powershell/9780471946939/9780471946939_enabling_scripts_on_your_machine.html?utm_source=openai))  \n- **RemoteSigned** \u2014 Allows locally created scripts. Scripts downloaded from the Internet need to be signed. ([techbloat.com](https://www.techbloat.com/how-to-allow-scripts-to-run-in-powershell.html?utm_source=openai))  \n- **AllSigned** \u2014 Only scripts signed by a trusted publisher can be run. Locally created scripts must be signed. ([techbloat.com](https://www.techbloat.com/how-to-allow-scripts-to-run-in-powershell.html?utm_source=openai))  \n- **Unrestricted** \u2014 Scripts run freely, with warnings for those downloaded from the Internet. ([oreilly.com](https://www.oreilly.com/library/view/professional-windows-r-powershell/9780471946939/9780471946939_enabling_scripts_on_your_machine.html?utm_source=openai))  \n- **Bypass** \u2014 No restrictions or warnings at all. Use with caution. ([techbloat.com](https://www.techbloat.com/how-to-allow-scripts-to-run-in-powershell.html?utm_source=openai))\n\n---\n\n## Setting a new execution policy\n\nTo change it, you use the `Set-ExecutionPolicy` cmdlet. You\u2019ll often need to run PowerShell *as an Administrator* to affect system-wide policies. ([makeuseof.com](https://www.makeuseof.com/enable-script-execution-policy-windows-powershell/?utm_source=openai))\n\n### Examples\n\n- To allow local scripts to run while still requiring downloaded scripts be signed (good balance for many users):\n\n  ```powershell\n  Set-ExecutionPolicy RemoteSigned\n  ```\n\n- To set only for the current user (no admin rights required):\n\n  ```powershell\n  Set-ExecutionPolicy RemoteSigned -Scope CurrentUser\n  ```\n\n- To allow all scripts without restrictions (less secure):\n\n  ```powershell\n  Set-ExecutionPolicy Unrestricted\n  ```\n\n- For a one-time bypass (only applies to the current session):\n\n  ```powershell\n  Set-ExecutionPolicy Bypass -Scope Process\n  ```\n\nWhen you run these, you'll usually be asked to confirm (Yes/No). You can force it without prompt with `-Force`. ([oreilly.com](https://www.oreilly.com/library/view/professional-windows-r-powershell/9780471946939/9780471946939_enabling_scripts_on_your_machine.html?utm_source=openai))\n\n---\n\n## Using Group Policy\n\nIf you\u2019re in an environment managed by IT, execution policies may be enforced via **Group Policy** rather than by local commands. You can find these settings under:\n\n```\nLocal Group Policy Editor \u2192 Administrative Templates \u2192 Windows Components \u2192 Windows PowerShell \u2192 Turn on Script Execution\n```\n\nHere you can set policies (e.g. allow remote-signed scripts, all_signed scripts, etc.) for all users or specific machines. ([learn.microsoft.com](https://learn.microsoft.com/en-us/windows/client-management/mdm/policy-csp-admx-powershellexecutionpolicy?utm_source=openai))\n\n---\n\n## Notes & best practices\n\n- Use **RemoteSigned** where possible \u2014 it\u2019s safer than `Unrestricted` or `Bypass` but usually doesn't block your own scripts. ([richardswinbank.net](https://richardswinbank.net/powershell/allow_local_scripts?utm_source=openai))  \n- If you only need to allow certain scripts temporarily, using the `Process` scope or launching PowerShell with `-ExecutionPolicy Bypass` can help. ([poshcode.gitbook.io](https://poshcode.gitbook.io/powershell-faq/src/getting-started/execution-policy?utm_source=openai))  \n- Scripts from the Internet may have an alternate data stream (Zone.Identifier) that requires proper signing under stricter policies. ([techbloat.com](https://www.techbloat.com/how-to-allow-scripts-to-run-in-powershell.html?utm_source=openai))\n\n---\n\nIf you like, I can walk you through setting this up safely for *your* environment (e.g. development vs production). Do you want that?"
