function Get-ComputerInfo { <# .SYNOPSIS Gathers detailed system information from a Linux system. .DESCRIPTION Collects and returns comprehensive system information including: - BIOS details (date, vendor, version) - CPU information (model, architecture, threads, cores, sockets) - Distribution details (name, version, support URL) - System disk metrics (total, free, used space in GB) - Graphics card information - Memory information - Kernel and OS details - System information (manufacturer, product name, version, serial) The function uses various Linux system commands and files: - lscpu: CPU information - uname: System and kernel information - lspci: Graphics card details - lsmem: Memory information - /etc/os-release: Distribution details - /sys/class/dmi/id/*: BIOS information (non-WSL) - WMI queries: BIOS information (WSL) - dmidecode: System information (requires sudo) .OUTPUTS PSCustomObject with the following properties: - BiosDate: DateTime of BIOS release - BiosVendor: Manufacturer of BIOS - BiosVersion: BIOS version string - CPU: Processor model name - CPUArchitecture: Processor architecture - CPUThreads: Total number of CPU threads - CPUCores: Total number of CPU cores - CPUSockets: Number of CPU sockets - DistName: Linux distribution name - DistSupportURL: Distribution's support URL - SystemDiskSize: Total system disk size - SystemDiskFree: Available disk space - SystemDiskUsed: Used disk space - GPU: Graphics card information - DistVersion: Distribution version - KernelRelease: Linux kernel version - OS: Operating system name - RAM: Total system memory - Manufacturer: System manufacturer - ProductName: System product name - SystemVersion: System version - SerialNumber: System serial number .NOTES Author: Emil Larsson Date: 2023-03-27 The script handles both native Linux and Windows Subsystem for Linux (WSL) environments, using different methods to gather BIOS information in each case. .EXAMPLE Get-ComputerInfo Returns a detailed object containing system information. #> [CmdletBinding()] param ( ) # Verifies required binary if (-not (Resolve-BinDep -Bins "lscpu", "awk", "lspci", "grep", "lsmem", "uname")) { return } $script:CPUData = lscpu | awk '/^Model name:/ || /^Socket\(s\):/ || /^Core\(s\) per socket:/ || /^Thread\(s\) per core:/ {print $0}' | Sort-Object $script:OSData = (Get-Content /etc/os-release) | Select-String -Pattern '(?<=NAME=|VERSION=|PRETTY_NAME=|HOME_URL=|SUPPORT_END=)[^,\n]+' -Raw # DisplayData $IsWSL = Get-Item Env:WSL_DISTRO_NAME -ErrorAction SilentlyContinue if ($IsWSL) { try { $DisplayData = powershell.exe -Command "Get-WmiObject Win32_VideoController | Select-Object -ExpandProperty Description" 2>$null if ([string]::IsNullOrEmpty($DisplayData)) { $DisplayData = "Unknown" } } catch { Write-Verbose "Unable to get GPU information from Windows host: $_" $DisplayData = "Unknown" } } else { $DisplayData = (lspci | grep -i vga) -split ":" | Select-Object -Last 1 if ($DisplayData -like " *") { $DisplayData = $DisplayData.TrimStart(" ") } } # Ram $RAM = (lsmem | Select-String 'Total online memory:' -Raw ).Split(': ')[1] if ($RAM -like "* *") { $RAM = $RAM.Replace(" ", "") } # Convert RAM to rounded GB if it ends with 'G' if ($RAM -match '(\d+\.?\d*)G$') { $ramValue = [decimal]$Matches[1] $RAM = "{0}GB" -f [Math]::Ceiling($ramValue) } # CPU Regex $CorePerSocket = $CPUData[0].Substring($CPUData[0].Length -
