SKILL.md Source
BusyBox is a single binary that implements many common Unix tools. Use this skill only on Windows. If you are on UNIX, then stop here. Run the following steps only if you cannot find a `busybox.exe` file in the same directory as this document is. These are PowerShell commands, if you have a classic `cmd.exe` terminal, then you must use `powershell -Command "..."` to run them. 1. Print the type of CPU: `Get-CimInstance -ClassName Win32_Processor | Select-Object Name, NumberOfCores, MaxClockSpeed` 2. Print the OS versions: `Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" | Select-Object ProductName, DisplayVersion, CurrentBuild` 3. Download a suitable build of BusyBox by running one of these PowerShell commands: - 32-bit x86 (ANSI): `$ProgressPreference = 'SilentlyContinue'; Invoke-WebRequest -Uri https://frippery.org/files/busybox/busybox.exe -OutFile busybox.exe` - 64-bit x86 (ANSI): `$ProgressPreference = 'SilentlyContinue'; Invoke-WebRequest -Uri https://frippery.org/files/busybox/busybox64.exe -OutFile busybox.exe` - 64-bit x86 (Unicode): `$ProgressPreference = 'SilentlyContinue'; Invoke-WebRequest -Uri https://frippery.org/files/busybox/busybox64u.exe -OutFile busybox.exe` - 64-bit ARM (Unicode): `$ProgressPreference = 'SilentlyContinue'; Invoke-WebRequest -Uri https://frippery.org/files/busybox/busybox64a.exe -OutFile busybox.exe` Useful commands: - Help: `busybox.exe --list` - Available UNIX commands: `busybox.exe --list` Usage: Prefix the UNIX command with `busybox.exe`, for example: `busybox.exe ls -1` If you need to run a UNIX command under another CWD, then use the absolute path to `busybox.exe`.
