        "content": "You\u2019re running into a limitation of PowerShell aliases: they can only map a name (alias) to a command/executable or function\u2014but *not* to a command **with arguments**. That means you can\u2019t use `Set-Alias` (or `New-Alias`) to alias `ls` *to include* the `-1` option directly. Here's a detailed breakdown and what you *can* do instead:\n\n---\n\n### Why your command doesn\u2019t work\n\n- PowerShell\u2019s `Set-Alias -Name ls -Value C:\\bin\\ls.exe -1` fails because `-1` is being interpreted as a parameter of `Set-Alias` (not part of the command you want to alias). `Set-Alias` doesn't accept arbitrary arguments to pass to the target executable. ([learn.microsoft.com](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/set-alias?view=powershell-7.5&utm_source=openai))  \n- As explained in Microsoft\u2019s docs, the `-Value` parameter must be \u201cthe name of the cmdlet or command\u201d \u2013 without additional arguments. ([learn.microsoft.com](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/set-alias?view=powershell-7.5&utm_source=openai))  \n- Multiple sources confirm aliases in PowerShell cannot embed parameters. To simulate an alias with specific default arguments, you use a function instead. ([delftstack.com](https://www.delftstack.com/howto/powershell/powershell-alias-with-parameters/?utm_source=openai))  \n\n---\n\n### How to get around this using a function + alias\n\nTo effectively alias `ls` to always run `C:\\bin\\ls.exe -1`, define a small PowerShell function, then alias that function to `ls`. Here\u2019s how:\n\n```powershell\nfunction ls1 {\n    & \"C:\\bin\\ls.exe\" -1 @Args\n}\n\nSet-Alias -Name ls -Value ls1\n```\n\nExplanation:\n\n- `function ls1 { ... }` defines a function named `ls1`.\n- The `&` is the *call operator* to run an external executable.\n- `@Args` passes through any arguments you give to `ls` when calling it.\n- Then `Set-Alias` sets `ls` to call your function `ls1`.\n\n---\n\n### Making it persistent\n\nIf you'd like this alias to be available in every PowerShell session:\n\n1. Open your PowerShell profile:  \n   ```powershell\n   notepad $PROFILE\n   ```\n2. Add the function and the alias lines into your profile file.\n3. Save it.\n4. Restart PowerShell (or run `. $PROFILE` to reload it).\n\n---\n\n### Full working example\n\nHere\u2019s a complete snippet you can put in your profile (`$PROFILE`):\n\n```powershell\nfunction ls1 {\n    & \"C:\\bin\\ls.exe\" -1 @Args\n}\n\nSet-Alias -Name ls -Value ls1\n```\n\nNow anytime you run `ls`, it\u2019ll execute `C:\\bin\\ls.exe -1`, plus whatever other arguments you give.\n\n---\n\nIf you like, I can also show you how to make this work cross-platform (e.g. in PowerShell Core) or handle different paths depending on environment. Want me to go ahead with that?"
