在VBS路径中使用空格运行Powershell脚本

Question

Can someone help with this script please? Basically, it's being ran by vbs and the options are set for each user running the script.

The script works as is on machines that support the dos 8.3 file system, but we also have quite a few imaged systems and do not have this ability...

So i'm fruitlessly trying to get the machines that do not support 8.3 to run this. Powershell does not like the space in the file path..., and I'm trying to run the script silently.

Objshell.Run "powershell.exe (gc c:\users\$env:USERNAME\Mydocu~1\Canadi~1\FileImportSettings.config) -replace 'temp','server\blahblah' | out-file c:\users\$env:USERNAME\Mydocu~1\Canadi~1\FileImportSettings.config",0

The comment was coming messy so I'm posting it further on to the original post..

What I had posted initially was part ofmy attempt at fixing the problem and it wouldn't run. This edited one does... But when I try changing it to doublequotes, the code no longer changes the username to %username%. I've tried running the command directly and cmd complains that out-file is not a recognised valid command.

Wscript.echo "powershell.exe (gc ""c:\users\""$env:USERNAME""\Documents\Canadian...\FileImportSettings.config"") -replace 'temp','server\blahblah' | out-file ""c:\users\""$env:USERNAME""\Documents\Canadian....\FileImportSettings.config""",0

Filenames with spaces in powershell.

Simple powershell command with no spaces in ( 8.3 aliased) path:

==>powershell (gc .\$env:USERNAME\yyyy.txt) -replace 'efg h','E FGH'
xxx1 abc D
xxx2 E FGH
xxx3 ijk L

Prepare for (long) file names with spaces in path (string concatenation). Single quote marks result in literal values being echoed back; double quote marks result in the actual value of a variable being echoed back):

powershell (gc $("'.\'"+$env:USERNAME+"'\yyyy.txt'")) -replace 'efg h','E FGH'

Replace ( 8.3 aliased) path with (long) file names with spaces in path:

powershell (gc $("'.\'"+$env:USERNAME+"'\yy yy.txt'")) -replace 'efg h','E FGH'

Pipe: | Out-file.

We must escape the | pipe character in next command to forward it to PoverShell ; otherwise, it applies in cmd shell with 'out-file' is not recognized as an internal or external command, operable program or batch file error.

powershell (gc $("'.\'"+$env:USERNAME+"'\yy yy.txt'")) -replace 'efg h','E FGH' ^| out-file $("'.\'"+$env:USERNAME+"'\yy yy.txt'")

VBScript.

Doubled all inner " double quote. Need to use absolute path for file name as for another working directory...

' 30064463
option explicit
Dim cmdLine, objShell
cmdLine = "powershell (gc $(""'D:\bat\'""+$env:USERNAME+""'\yy yy.txt'"")) -replace 'efg h','E FGH' ^| out-file $(""'D:\bat\'""+$env:USERNAME+""'\yy yy.txt'"")"
Wscript.Echo cmdLine
Set objShell = WScript.CreateObject("WScript.Shell")
Objshell.Run "cmd /C " & cmdLine, 1, true
Wscript.Quit

Output.

==>type  "D:\BAT\%username%\yy yy.txt"
xxx1 abc D
xxx2 efg H
xxx3 ijk L

==>cscript D:\VB_scripts\SO\30064463.vbs
powershell (gc $("'D:\bat\'"+$env:USERNAME+"'\yy yy.txt'")) -replace 'efg h','
E FGH' ^| out-file $("'D:\bat\'"+$env:USERNAME+"'\yy yy.txt'")

==>type  "D:\BAT\%username%\yy yy.txt"
xxx1 abc D
xxx2 E FGH
xxx3 ijk L
