To specify the program that runs in the process, enter an executable file or script file, or a file that can be opened by using a program on the computer. If you specify a non-executable file, Start-Process starts the program that is associated with the file, much like the Invoke-Item cmdlet. You can use the parameters of Start-Process to specify options, such as loading a user profile, starting the process in a new window, or using alternate credentials.PARAMETERS-ArgumentList <string[]> Specifies parameters or parameter values to use when starting the process. The parameter name ("Arguments") is optional.

By default, this cmdlet does not generate any output. Required? false Position? named Default value False Accept pipeline input? false Accept wildcard characters? false -RedirectStandardError <string> Sends any errors generated by the process to a file that you specify. Enter the path and file name. By default, the errors are displayed in the console.

EXAMPLE 1C:\PS>start-process sort.exeDescription----------- This command starts a process that uses the Sort.exe file in the current directory. The command uses all of the default values, including the default window style, working directory, and credentials.EXAMPLE 2C:\PS>start-process myfile.txt -workingdirectory "C:\PS-Test" -verb PrintDescription----------- This command starts a process that prints the C:\PS-Test\MyFile.txt file.EXAMPLE 3C:\PS>start-process Sort.exe -RedirectStandardInput Testsort.txt -RedirectStandardOutput Sorted.txt -RedirectStandardError SortError.txt -UseNewEnvironmentDescription----------- This command starts a process that sorts items in the Testsort.txt file and returns the sorted items in the Sorted.txt files. Any errors are written to the SortError.txt file. The UseNewEnvironment parameter specifies that the process runs with its own environment variables.EXAMPLE 4C:\PS>start-process notepad -wait -windowstyle MaximizedDescription----------- This command starts the Notepad process.
