Where is powershell located in windows 1011/11/2023 Precedence among external executables and *.ps1 scripts: Should there be multiple external executables whose base file name is where, it is the one from the directory listed earliest in $env:PATH that will be executed - see next section. & (Get-Command -Type Application where) git In cases where this is not possible (e.g., on Unix-like platforms, where executables typically do not have a filename extension or if an alias shadows a function), you can use the -Type parameter to get the command of interest, and invoke it with &, the call operator: # Invokes where.exe, as only it is of type 'Application' (external executable) exe extension that can distinguish it from the where alias, it is simplest to invoke where.exe with the filename extension, as shown at the top. Given that the where.exe executable file name has the. The result shows that the built-in where alias for the Where-Object cmdlet (whose purpose is to filter pipeline input) is the effective command when you submit where, and not the desired where.exe executable. PS> Get-Command -All whereĪpplication where.exe 10.0.18. external executables, including *.ps1 script files - see bottom sectionĪn easy way to see what command types exist for a given name is to add the -All switch when calling the Get-Command cmdlet, which lists the matching commands in descending order of precedence that is, the command that will actually be executed via the given name is listed first. cmdlets (loosely speaking: functions implemented as compiled binaries).This precedence is documented in the conceptual about_Command_Precedence help topic in short, here is the command precedence by type in descending order (highest precedence first): That is, if a given command name matches two or more commands, it is their type that determines which command is actually invoked. PowerShell has different types of commands, which - in the case of name conflicts - have a predefined order of precedence to determine what type should be the effective command. Get-Command doesn't do that, because PowerShell by design, for security reasons, doesn't allow calling executables located in the current directory by name only - a path is required (e.g. Unlike Get-Command, where.exe also finds executables located in the current directory. Where.exe finds only executable files, whereas Get-Command by default looks for all command types (aliases, functions, cmdlets. Source property contains the full path for a command-info object representing an external executable: PS> (Get-Command git).Source Where.exe, whose purpose is return the full path of an executable in the system's path (in one of the directories listed in the $env:PATH environment variable), is unrelated to cmd (the legacy command processor): it is an external executable that comes with Windows, and it can be invoked from any shell, and therefore also from PowerShell.īy contrast, cmd does have so-called internal commands that indeed can only be called from cmd, such as mklink in fact, in cmd you can use where to infer whether a given (functioning) command is internal or not: if there's no output, the command is internal (or doesn't exist at all).Īlternatively, use the equivalent and more flexible PowerShell counterpart to where.exe, the Get-Command cmdlet it returns instances (or instances of derived classes), whose. # from PowerShell's built-in 'where' alias (for 'Where-Object'). exe explicitly: # Note the use of '.exe' to disambiguate the external 'where.exe' program Where is PowerShell's built-in alias for the Where-Object cmdlet to invoke the external where.exe program, use. The existing answers are helpful, but I think a more systematic discussion is helpful too.
