Introducción
Aquí está mi Invoke-RawPipeline función (obtenga la última versión de este Gist).
Úselo para canalizar datos binarios entre los flujos de entrada y salida estándar de los procesos. Puede leer el flujo de entrada de un archivo / canalización y guardar el flujo de salida resultante en un archivo.
Requiere el módulo PsAsync para poder lanzar y canalizar datos en múltiples procesos.
En caso de problemas, utilice -Verbose cambie para ver la salida de depuración.
Ejemplos de
Redirigiendo al archivo
- Lote:
findstr.exe /C:"Warning" /I C:WindowsWindowsUpdate.log > C:WU_Warnings.txt - Potencia Shell:
Invoke-RawPipeline -Command @Path = 'findstr.exe' ; Arguments = '/C:"Warning" /I C:WindowsWindowsUpdate.log' -OutFile 'C:WU_Warnings.txt'
Redirigiendo desde archivo
- Lote:
svnadmin load < C:RepoDumpsMyRepo.dump - Potencia Shell:
Invoke-RawPipeline -InFile 'C:RepoDumpsMyRepo.dump' -Command @Path = 'svnadmin.exe' ; Arguments = 'load'
Cuerdas de tubería
- Lote:
echo TestString | find /I "test" > C:SearchResult.log - Potencia Shell:
'TestString' | Invoke-RawPipeline -Command @Path = 'find.exe' ; Arguments = '/I "test"' -OutFile 'C:SearchResult.log'
Tubería entre múltiples procesos
- Lote:
ipconfig | findstr /C:"IPv4 Address" /I - Potencia Shell:
Invoke-RawPipeline -Command @Path = 'ipconfig', @Path = 'findstr' ; Arguments = '/C:"IPv4 Address" /I' -RawData

.Synopsis
Pipe binary data between processes' Standard Output and Standard Input streams.
Can read input stream from file and save resulting output stream to file.
.Description

.Component
Requires PsAsync module: http://psasync.codeplex.com
.Parameter Command
An array of hashtables, each containing Command Name, Working Directory and Arguments
.Parameter InFile
This parameter is optional.
A string representing path to file, to read input stream from.
.Parameter OutFile
This parameter is optional.
A string representing path to file, to save resulting output stream to.
.Parameter Append
This parameter is optional. Default is false.
A switch controlling wheither ovewrite or append output file if it already exists. Default is to overwrite.
.Parameter IoTimeout
This parameter is optional. Default is 0.
A number of seconds to wait if Input/Output streams are blocked. Default is to wait indefinetely.
.Parameter ProcessTimeout
This parameter is optional. Default is 0.
A number of seconds to wait for process to exit after finishing all pipeline operations. Default is to wait indefinetely.
Details: https://msdn.microsoft.com/en-us/library/ty0d8k56.aspx
.Parameter BufferSize
This parameter is optional. Default is 4096.
Size of buffer in bytes for readwrite operations. Supports standard Powershell multipliers: KB, MB, GB, TB, and PB.
Total number of buffers is: Command.Count * 2 + InFile + OutFile.
.Parameter ForceGC
This parameter is optional.
A switch, that if specified will force .Net garbage collection.
Use to immediately release memory on function exit, if large buffer size was used.
.Parameter RawData
This parameter is optional.
By default function returns object with StdOut/StdErr streams and process' exit codes.
If this switch is specified, function will return raw Standard Output stream.
.Example
Invoke-RawPipeline -Command @Path = 'findstr.exe' ; Arguments = '/C:"Warning" /I C:WindowsWindowsUpdate.log' -OutFile 'C:WU_Warnings.txt'
Batch analog: findstr.exe /C:"Warning" /I C:WindowsWindowsUpdate.log' > C:WU_Warnings.txt
.Example
Invoke-RawPipeline -Command @Path = 'findstr.exe' ; WorkingDirectory = 'C:Windows' ; Arguments = '/C:"Warning" /I .WindowsUpdate.log' -RawData
Batch analog: cd /D C:Windows && findstr.exe /C:"Warning" /I .WindowsUpdate.log
.Example
'TestString' | Invoke-RawPipeline -Command @Path = 'find.exe' ; Arguments = '/I "test"' -OutFile 'C:SearchResult.log'
Batch analog: echo TestString | find /I "test" > C:SearchResult.log
.Example
Invoke-RawPipeline -Command @Path = 'ipconfig', @Path = 'findstr' ; Arguments = '/C:"IPv4 Address" /I' -RawData
Batch analog: ipconfig | findstr /C:"IPv4 Address" /I
.Example
Invoke-RawPipeline -InFile 'C:RepoDumpsRepo.svn' -Command @Path = 'svnadmin.exe' ; Arguments = 'load'
Batch analog: svnadmin load < C:RepoDumpsMyRepo.dump
