I currently have a .cmd file that runs the following two commands on startup
PowerShell -Command "Set-ExecutionPolicy Unrestricted" >> "%TEMP%\StartupLog.txt" 2>&1
PowerShell C:\Users\elias\Desktop\Script123.ps1 >> "%TEMP%\StartupLog.txt" 2>&1
But when this runs on startup it shows the command prompt. I'm wondering if there's anyway to run this without showing the command prompt.
Thank You
Invoking a .cmd file directly invariably opens a console window, so you need to invoke it via a wrapper executable that hides it:
This answer of mine contains a VBScript script that does just that; assuming you've saved it as runHidden.vbs in the current dir and that you want to invoke some-batch-file.cmd from the current dir:
wscript .\runHidden.vbs cmd "/c .\some-batch-file.cmd"
Try powershell -command "& { $x = New-Object -ComObject Shell.Application; $x.minimizeall() }" in the beginning of the code.
This command can minimize all windows.
I hope this can be helpful, if you have any other questions, please comment below.
Create a wrapper with VBScript:
Option Explicit
Dim WshShell
Set WshShell = CreateObject("WScript.Shell")
WshShell.Run "cmd /c blah.cmd", 0, False
Then change the startup item to
wscript.exe wrapper.vbs

So I am trying to write a script that allows me to open several cmd command prompt and write in them the same command but with different variables.
The solution that I came with was to write a PowerShell script that calls inside a loop a cmd file and pass a variable each time to the cmd file but I'm stuck, the PowerShell script execute only one cmd.
Can someone help to figure this out ?
Thanks :)
You can use the following :
cmd.exe /c [command]
for example
$x = 1..100
foreach ($n in $x){cmd.exe /c ping 192.168.1.$n}
mohamed saeed's answer shows you to execute cmd.exe commands synchronously, in sequence in the current console window.
If, by contrast, you want to open multiple interactive cmd.exe sessions, asynchronously, each in its separate, new window, use cmd.exe's /k option and invoke cmd.exe via Start-Process:
# Open three new interactive cmd.exe sessions in new windows
# and execute a sample command in each.
'date /t', 'ver', "echo $PSHOME" | ForEach-Object {
# Parameters -FilePath and -ArgumentList implied.
Start-Process cmd.exe /k, $_
}
Note:
Unless your cmd.exe console windows have the Let the system position the window checkbox in the Properties dialog checked by default, all new windows will fully overlap, so that you'll immediately only see the last one opened.
The last new window opened will have the keyboard focus.
The commands passed to /k are instantly executed, but an interactive session is then entered.
If you would like to keep in purely batch, you can use the start command. The /k switch keeps the command line open. You would use /c if you want to carry out the command and terminate :
start "" %comspec% /k ping 192.168.1.1
From powershell, you can use the Start-Process command with an ArgumentList:
Start-Process cmd.exe -ArgumentList "/k ping 192.168.1.1"
I'm writing a Powershell script that takes in a text file as a parameter. The text file looks similar to this:
echo "1"
echo "2"
echo "3"
What I would want is for each line to be executed in a new Powershell instance. So in the example above, 3 additional instances would be created and each of the 3 would execute one line from the text file. I'm able to launch instances, but I cannot get the instances to treat the lines in the file as commands.
$textFile=$args[0] #File with Powershell commands
foreach($cmdd in get-content $textFile){
cmd /c start powershell -NoExit -command {param($cmdd) iex $cmdd} -ArgumentList $cmdd
}
Running this code opens the instances, prints a lot of information, and then immediately closes. It closes so quickly that I cannot see what the info is. However, since the text file is only composed of printing the numbers 1, 2, and 3, I don't think that it's working correctly. Is there also a way to keep the windows from closing after execution?
If you're launching additional instances of PowerShell from PowerShell, you won't need to call cmd. Try using Start-Process:
$textFile=$args[0] #File with Powershell commands
foreach($cmdd in get-content $textFile){
Start-Process -FilePath powershell -ArgumentList "-NoExit -Command $cmdd"
}
This will leave newly created instances open as you have asked.
Switch from CMD /C to CMD /K to leave the command session open after the command finishes.
I am having a bunch of issues with getting a PowerShell command to run. All it is doing is running a command that would be run in a CMD prompt window.
Here is the command:
"C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\i386\CmRcViewer.exe" PCNAME
I have tried the following with no success (I have tried many iterations of this to try and get one that works. Syntax is probably all screwed up):
$TEXT = $textbox.Text #$textbox is where the user enters the PC name.
$CMDCOMMAND = "C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\i386\CmRcViewer.exe"
Start-Process '"$CMDCOMMAND" $TEXT'
#iex -Command ('"C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\i386\CmRcViewer.exe"' $TEXT)
The command will just open SCCM remote connection window to the computer the user specifies in the text box.
Try this:
& "C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\i386\CmRcViewer.exe" PCNAME
To PowerShell a string "..." is just a string and PowerShell evaluates it by echoing it to the screen. To get PowerShell to execute the command whose name is in a string, you use the call operator &.
To run or convert batch files externally from PowerShell (particularly if you wish to sign all your scheduled task scripts with a certificate) I simply create a PowerShell script, e.g. deletefolders.ps1.
Input the following into the script:
cmd.exe /c "rd /s /q C:\#TEMP\test1"
cmd.exe /c "rd /s /q C:\#TEMP\test2"
cmd.exe /c "rd /s /q C:\#TEMP\test3"
*Each command needs to be put on a new line calling cmd.exe again.
This script can now be signed and run from PowerShell outputting the commands to command prompt / cmd directly.
It is a much safer way than running batch files!
One solution would be to pipe your command from PowerShell to CMD. Running the following command will pipe the notepad.exe command over to CMD, which will then open the Notepad application.
PS C:\> "notepad.exe" | cmd
Once the command has run in CMD, you will be returned to a PowerShell prompt, and can continue running your PowerShell script.

CMD's Startup Message is Shown
As mklement0 points out, this method shows CMD's startup message. If you were to copy the output using the method above into another terminal, the startup message will be copied along with it.
For those who may need this info:
I figured out that you can pretty much run a command that's in your PATH from a PS script, and it should work.
Sometimes you may have to pre-launch this command with cmd.exe /c
Examples
Calling git from a PS script
I had to repackage a git client wrapped in Chocolatey (for those who may not know, it's a package manager for Windows) which massively uses PS scripts.
I found out that, once git is in the PATH, commands like
$ca_bundle = git config --get http.sslCAInfo
will store the location of git crt file in $ca_bundle variable.
Looking for an App
Another example that is a combination of the present SO post and this SO post is the use of where command
$java_exe = cmd.exe /c where java
will store the location of java.exe file in $java_exe variable.
You must use the Invoke-Command cmdlet to launch this external program. Normally it works without an effort.
If you need more than one command you should use the Invoke-Expression cmdlet with the -scriptblock option.
I would like to run .exe hidden or minimized in windows but it doesnt work.
i tried in cmd: start /min something.exe
in powershell: start-process -WindowStyle Hidden something.exe
it works with something.txt, .log etc
with cmd you can not do this. you can use vbscript instead
1. create a file run.vbs
2. put,
Dim sh
Set sh = WScript.CreateObject("WScript.Shell")
sh.run "cmd /K something.exe & exit", 0 ,false
Set sh = Nothing
in run.vbs
3. save and double click to run.
hope this will work..
I am very new to powershell and sometimes this question may be so simple
Can please anybody please tell me what is the equivalent to the following(vbscript) in PowerShell
set obj = wscript.createobject( wscript.shell )
Obj.Run $smCmnd
What is the use of wscript.shell.
After a bit of search I found first line can be presented as;
$obj = New-Object -ComObject WScript.Shell
But have have no idea how to call Run method ($obj.run(...)???)
If I run cmd.exe with some commands as the smCmnd, How can I keep cmd.exe without close and to run another command later in same console??
EDIT
I am writing PS script and it will be call from another application. Basically it will do some folder creations and file coping etc. I would like to open CMD.exe and show all the commands running on that. How to use same cmd prompt through out my whole script.
Is smCmnd a string of shell commands? If so, you can call them directly from PowerShell, without trying to get a wscript.shell COM object to run them against like you'd need to do in VBScript.
VBScript wasn't a shell. Powershell is. You can write shell commands directly in .ps1 or .ps2 files, just like in a batch file.
I'm not a powershell expert here, but try doing
& $smCmnd
Try running $smCmnd directly. If that fails, use Invoke-Expression $smCmnd.
If you do need to use CMD.EXE (possibly because you want to run pre-existing BAT file), and you want all of the output in a single CMD window you can pipe all the input into cmd at once like this:
# Powershell script to execute existing BAT file
cmd.exe /k "cd c:\batchfiles & firstone.bat & second.bat & echo that's all folks"
# CMD will remain open (/k). User will have to type exit to return to powershell
# Or if you want user just to hit any key to leave CMD prompt:
cmd.exe /c "c:\batchfiles\mybatchfile.bat & pause"
# /C means CMD should close after is has executed the commands on the command line
However if you want to have something execute in CMD, then make a decision in your Powershell script about what to execute next in CMD then do something similar to the answer at the following link which pipes input and output between a powershell script and CMD.exe.
