How do you run the following command in PowerShell?
C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe -verb:sync -source:dbfullsql="Data Source=mysource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;" -dest:dbfullsql="Data Source=.\mydestsource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;",computername=10.10.10.10,username=administrator,password=adminpass"
When PowerShell sees a command starting with a string it just evaluates the string, that is, it typically echos it to the screen, for example:
PS> "Hello World"
Hello World
If you want PowerShell to interpret the string as a command name then use the call operator (&) like so:
PS> & 'C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe'
After that you probably only need to quote parameter/argument pairs that contain spaces and/or quotation chars. When you invoke an EXE file like this with complex command line arguments it is usually very helpful to have a tool that will show you how PowerShell sends the arguments to the EXE file. The PowerShell Community Extensions has such a tool. It is called echoargs. You just replace the EXE file with echoargs - leaving all the arguments in place, and it will show you how the EXE file will receive the arguments, for example:
PS> echoargs -verb:sync -source:dbfullsql="Data Source=mysource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;" -dest:dbfullsql="Data Source=.\mydestsource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;",computername=10.10.10.10,username=administrator,password=adminpass
Arg 0 is <-verb:sync>
Arg 1 is <-source:dbfullsql=Data>
Arg 2 is <Source=mysource;Integrated>
Arg 3 is <Security=false;User>
Arg 4 is <ID=sa;Pwd=sapass!;Database=mydb;>
Arg 5 is <-dest:dbfullsql=Data>
Arg 6 is <Source=.\mydestsource;Integrated>
Arg 7 is <Security=false;User>
Arg 8 is <ID=sa;Pwd=sapass!;Database=mydb; computername=10.10.10.10 username=administrator password=adminpass>
Using echoargs you can experiment until you get it right, for example:
PS> echoargs -verb:sync "-source:dbfullsql=Data Source=mysource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;"
Arg 0 is <-verb:sync>
Arg 1 is <-source:dbfullsql=Data Source=mysource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;>
It turns out I was trying too hard before to maintain the double quotes around the connection string. Apparently that isn't necessary because even cmd.exe will strip those out.
BTW, hats off to the PowerShell team. They were quite helpful in showing me the specific incantation of single & double quotes to get the desired result - if you needed to keep the internal double quotes in place. :-) They also realize this is an area of pain, but they are driven by the number of folks are affected by a particular issue. If this is an area of pain for you, then please vote up this PowerShell bug submission.
For more information on how PowerShell parses, check out my Effective PowerShell blog series - specifically item 10 - "Understanding PowerShell Parsing Modes"
UPDATE 4/4/2012: This situation gets much easier to handle in PowerShell V3. See this blog post for details.
I had spaces in both command and parameters, and this is what worked for me:
$Command = "E:\X64\Xendesktop Setup\XenDesktopServerSetup.exe"
$Parms = "/COMPONENTS CONTROLLER,DESKTOPSTUDIO,DESKTOPDIRECTOR,LICENSESERVER,STOREFRONT /PASSIVE /NOREBOOT /CONFIGURE_FIREWALL /NOSQL"
$Parms = $Parms.Split(" ")
& "$Command" $Parms
It's basically the same as Akira's answer, but this works if you dynamically build your command parameters and put them in a variable.
Just add the & operator before the .exe name.
Here is a command to install SQL Server Express in silence mode:
$fileExe = "T:\SQLEXPRADV_x64_ENU.exe"
$CONFIGURATIONFILE = "T:\ConfSetupSql2008Express.ini"
& $fileExe /CONFIGURATIONFILE=$CONFIGURATIONFILE
There are quite a few methods you can use to do it.
There are other methods like using the Call Operator (&), Invoke-Expression cmdlet etc. But they are considered unsafe. Microsoft recommends using Start-Process.
Method 1
A simple example
Start-Process -NoNewWindow -FilePath "C:\wamp64\bin\mysql\mysql5.7.19\bin\mysql" -ArgumentList "-u root","-proot","-h localhost"
In your case
Start-Process -NoNewWindow -FilePath "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" -ArgumentList "-verb:sync","-source:dbfullsql=`"Data Source=mysource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;`"","-dest:dbfullsql=`"Data Source=.\mydestsource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;`"","computername=10.10.10.10","username=administrator","password=adminpass"
In this method you separate each and every parameter in the ArgumentList using commas.
Method 2
Simple Example
Start-Process -NoNewWindow -FilePath "C:\wamp64\bin\mysql\mysql5.7.19\bin\mysql" -ArgumentList "-u root -proot -h localhost"
In your case
Start-Process -NoNewWindow -FilePath "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" -ArgumentList "-verb:sync -source:dbfullsql=`"Data Source=mysource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;`" -dest:dbfullsql=`"Data Source=.\mydestsource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;`",computername=10.10.10.10,username=administrator,password=adminpass"
This method is easier as it allows to type your parameters in one go.
Note that in powershell to represent the quotation mark ( " ) in a string you should insert the grave accent ( ` ) (This is the key above the Tab key in the US keyboard).
-NoNewWindow
parameter is used to display the new process in the current console window. By default Windows PowerShell opens a new window.

This worked for me:
& 'D:\Server\PSTools\PsExec.exe' #('\\1.1.1.1', '-accepteula', '-d', '-i', $id, '-h', '-u', 'domain\user', '-p', 'password', '-w', 'C:\path\to\the\app', 'java', '-jar', 'app.jar')
Just put paths or connection strings in one array item and split the other things in one array item each.
There are a lot of other options here: https://social.technet.microsoft.com/wiki/contents/articles/7703.powershell-running-executables.aspx
Microsoft should make this way simpler and compatible with command prompt syntax.
In case somebody is wondering how to just run an executable file:
..... > .\file.exe
or
......> full\path\to\file.exe
See this page:
https://slai.github.io/posts/powershell-and-external-commands-done-right/
Summary using vshadow as the external executable:
$exe = "H:\backup\scripts\vshadow.exe"
&$exe -p -script=H:\backup\scripts\vss.cmd E: M: P:
You can use:
Start-Process -FilePath "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" -ArgumentList "-verb:sync -source:dbfullsql="Data Source=mysource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;" -dest:dbfullsql="Data Source=.\mydestsource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;",computername=10.10.10.10,username=administrator,password=adminpass"
The key thing to note here is that FilePath must be in position 0, according to the Help Guide. To invoke the Help guide for a commandlet, just type in Get-Help <Commandlet-name> -Detailed . In this case, it is Get-Help Start-Process -Detailed.
I was able to get my similar command working using the following approach:
msdeploy.exe -verb=sync "-source=dbFullSql=Server=THESERVER;Database=myDB;UID=sa;Pwd=saPwd" -dest=dbFullSql=c:\temp\test.sql
For your command (not that it helps much now), things would look something like this:
msdeploy.exe -verb=sync "-source=dbfullsql=Server=mysource;Trusted_Connection=false;UID=sa;Pwd=sapass!;Database=mydb;" "-dest=dbfullsql=Server=mydestsource;Trusted_Connection=false;UID=sa;Pwd=sapass!;Database=mydb;",computername=10.10.10.10,username=administrator,password=adminpass
The key points are:
Use quotes around the source argument, and remove the embedded quotes around the connection string
Use the alternative key names in building the SQL connection string that don't have spaces in them. For example, use "UID" instead of "User Id", "Server" instead of "Data Source", "Trusted_Connection" instead of "Integrated Security", and so forth. I was only able to get it to work once I removed all spaces from the connection string.
I didn't try adding the "computername" part at the end of the command line, but hopefully this info will help others reading this now get closer to their desired result.
New escape string in PowerShell V3, quoted from New V3 Language Features:
Easier Reuse of Command Lines From Cmd.exe
The web is full of command lines written for Cmd.exe. These commands lines work often enough in PowerShell, but when they include certain characters, for example, a semicolon (;), a dollar sign ($), or curly braces, you have to make some changes, probably adding some quotes. This seemed to be the source of many minor headaches.
To help address this scenario, we added a new way to “escape” the parsing of command lines. If you use a magic parameter --%, we stop our normal parsing of your command line and switch to something much simpler. We don’t match quotes. We don’t stop at semicolon. We don’t expand PowerShell variables. We do expand environment variables if you use Cmd.exe syntax (e.g. %TEMP%). Other than that, the arguments up to the end of the line (or pipe, if you are piping) are passed as is. Here is an example:
PS> echoargs.exe --% %USERNAME%,this=$something{weird}
Arg 0 is <jason,this=$something{weird}>
I use this simple, clean and effective method.
I place arguments in an array, 1 per line. This way it is very easy to read and edit.
Then I use a simple trick of passing all arguments inside double quotes to a function with 1 single parameter. That flattens them, including arrays, to a single string, which I then execute using PS's 'Invoke-Expression'. This directive is specifically designed to convert a string to runnable command.
Works well:
# function with one argument will flatten
# all passed-in entries into 1 single string line
Function Execute($command) {
# execute:
Invoke-Expression $command;
# if you have trouble try:
# Invoke-Expression "& $command";
# or if you need also output to a variable
# Invoke-Expression $command | Tee-Object -Variable cmdOutput;
}
# ... your main code here ...
# The name of your executable app
$app = 'my_app.exe';
# List of arguments:
# Notice the type of quotes - important !
# Those in single quotes are normal strings, like 'Peter'
$args = 'arg1',
'arg2',
$some_variable,
'arg4',
"arg5='with quotes'",
'arg6',
"arg7 \ with \ $other_variable",
'etc...';
# pass all arguments inside double quotes
Execute "$app $args";
I tried all of the suggestions but was still unable to run msiexec.exe with parameters that contained spaces. So my solution ended up using System.Diagnostics.ProcessStartInfo:
# can have spaces here, no problems
$settings = #{
CONNECTION_STRING = "... ..."
ENTITY_CONTEXT = "... ..."
URL = "..."
}
$settingsJoined = ($settings.Keys | % { "$_=""$($settings[$_])""" }) -join " "
$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pinfo.WorkingDirectory = $ScriptDirectory
$pinfo.FileName = "msiexec.exe"
$pinfo.RedirectStandardError = $true
$pinfo.RedirectStandardOutput = $true
$pinfo.UseShellExecute = $false
$pinfo.Arguments = "/l* install.log /i installer.msi $settingsJoined"
$p = New-Object System.Diagnostics.Process
$p.StartInfo = $pinfo
$p.Start() | Out-Null
$stdout = $p.StandardOutput.ReadToEnd()
$p.WaitForExit()
You can run exe files in powershell different ways. For instance if you want to run unrar.exe and extract a .rar file you can simply write in powershell this:
$extract_path = "C:\Program Files\Containing folder";
$rar_to_extract = "C:\Path_to_arch\file.rar"; #(or.exe if its a big file)
C:\Path_here\Unrar.exe x -o+ -c- $rar_to_extract $extract_path;
But sometimes, this doesn't work so you must use the & parameter as shown above:
For instance, with vboxmanage.exe (a tool to manage virtualbox virtual machines) you must call the paramterers outside of the string like this, without quotes:
> $vmname = "misae_unrtes_1234123"; #(name too long, we want to change this)
> & 'C:\Program Files\Oracle\VirtualBox\VBoxManage.exe' modifyvm $vmname --name UBUNTU;
If you want to call simply a winrar archived file as .exe files, you can also unzip it with the invoke-command cmdlet and a Silent parameter /S (Its going to extract itself in the same folder than where it has been compressed).
> Invoke-Command -ScriptBlock { C:\Your-path\archivefile.exe /S };
So there are several ways to run .exe files with arguments in powershell.
Sometimes, one must find a workaround to make it work properly, which can require some further effort and pain :) depending on the way the .exe has been compiled or made by its creators.
Cmd can handle running a quoted exe, but Powershell can't. I'm just going to deal with running the exe itself, since I don't have it. If you literally need to send doublequotes to an argument of an external command, that's another issue that's been covered elsewhere.
1) add the exe folder to your path, maybe in your $profile
$env:path += ';C:\Program Files\IIS\Microsoft Web Deploy\'
msdeploy
2) backquote the spaces:
C:\Program` Files\IIS\Microsoft` Web` Deploy\msdeploy.exe
This worked for me:
PowerShell.exe -Command "& ""C:\Some Script\Path With Spaces.ps1"""
The key seems to be that the whole command is enclosed in outer quotes, the "&" ampersand is used to specify another child command file is being executed, then finally escaped (doubled-double-) quotes around the path/file name with spaces in you wanted to execute in the first place.
This is also completion of the only workaround to the MS connect issue that -File does not pass-back non-zero return codes and -Command is the only alternative. But until now it was thought a limitation of -Command was that it didn't support spaces. I've updated that feedback item too.

An alternative answer is to use a Base64 encoded command switch:

When decoded, you'll see it's the OP's original snippet with all arguments and double quotes preserved.
powershell.exe -EncodedCommand
Accepts a base-64-encoded string version of a command. Use this parameter
to submit commands to Windows PowerShell that require complex quotation
marks or curly braces.
The original command:
C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe -verb:sync -source:dbfullsql="Data Source=mysource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;" -dest:dbfullsql="Data Source=.\mydestsource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;",computername=10.10.10.10,username=administrator,password=adminpass"

From Jeffery Hicks Aarticle
Other answers address the arguments.
If you just need to run a file in the current directory and don't feel like spelling out the entire path use Get-Location:
& "$(Get-Location)\example.exe" arg1 arg2 arg3
Note the & at the start. Spaced arguments are to be placed after the quotes.
I had the following code working perfect on my laptop:
& $msdeploy `
-source:package="$publishFile" `
-dest:auto,computerName="$server",includeAcls="False",UserName="$username",Password="$password",AuthType="$auth" `
-allowUntrusted `
-verb:sync `
-enableRule:DoNotDeleteRule `
-disableLink:AppPoolExtension `
-disableLink:ContentExtension `
-disableLink:CertificateExtension `
-skip:objectName=filePath,absolutePath="^(.*Web\.config|.*Environment\.config)$" `
-setParam:name=`"IIS Web Application Name`",value="$appName"
Then when I tried to run that directly on one server I started getting those errors "Unrecognized argument ...etc.... All arguments must begin with "-". "
After trying all possible workarounds (no success), I found out that Powershell on the server (Windows 2008 R2) was version 3.0, while my laptop has 5.0. (you can use "$PSVersionTable" to see version).
After upgrading Powershell to latest version it started working again.
So, I ran into a similar problem and chose to solve it this way instead:
Escape your quote (") characters with a backtick (`)
Surround your new expression with quotes (")
Using the call operator (&), issue the command invoke-expression on the new string
Example solution:
& { invoke-expression "C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe -verb:sync -source:dbfullsql=`"Data Source=mysource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;`" -dest:dbfullsql=`"Data Source=.\mydestsource;Integrated Security=false;User ID=sa;Pwd=sapass!;Database=mydb;`",computername=10.10.10.10,username=administrator,password=adminpass`"" }
To transfer a batch script using exiftool.exe to a powershell script I had the challange to give '-s, "-s and even ${Filename} to the command and on the other hand fill out variables in these parameters.
For a start: The replacement in using 'echochars' is brilliant. It clearly shows what is grouped as a single parameter and what ends up as the next parameter.
In powershell it is similar to perl (and unix scripting): the used quotes have their meaning.
strings between "-s. The string will be interpreted (variables filled)
Strings between '-s. The string will not be interpreted (or verry limited)
the escape character is ` (the back-quote). The next character looses its special meaning. Comparable with the \ (back stroke) on unix/linux/perl.
Some examples:
${ExifArgs} += "-if `"`${FileName} !~ /desktop.ini/i`""
${ExifArgs} += '-dateFormat "%Y\%Y%m\%Y%m%d_%H%M%S"'
${ExifArgs} += ('"' + "-FileName<${NewFotos}\${SourceName}\" + '${DateTimeOriginal}_${ImageWidth}x${ImageHeight}_${Model;s/ //g}_${FileName;s/^.*([0-9]{4})[^0-9].*$/\1/}.%e' + '"')
A call to echoargs with the above, produces the next output (numbers are hacked for privacy):
Arg 11 is <-if>
Arg 12 is <${FileName} !~ /desktop.ini/i>
Arg 13 is <-dateFormat>
Arg 14 is <%Y\%Y%m\%Y%m%d_%H%M%S>
Arg 15 is <-FileName<D:\Pictures\NewFotos\${DateTimeOriginal}_${ImageWidth}x${ImageHeight}_${Model;s/ //g}_${FileName;s/^.*([0-9]{4})[^0-9].*$/\1/}.%e>
See how the first line produces arg 11 and 12: the outher "-s are removed to store the entire line in the array. The inner "-s, quoted by the `-s are there to keep the argument together (while the -if is the previous argument)
The second shows arg 13 and 14: the use of "-s between '-s. No need to escape using `-s.
In the last line (producing arg 15): the single string is constructed by using powershell ()-s and +-s to concatenate a couple of strings to a single string. It uses both " and ' delimited strings to have som ${}-s filled out by powershell and some for exiftool.
And yes, some powershell special characters are transvered into the archuments.

In my machine , this location content , windows bat file. "D/too/w.bat". This bat file can run in cmd , like this w.bat I :/ o:/ In Powershell , can run like this "./w.bat i: o:/" . now I , need to run it using some automated .ps script. I try like bellow ,
#
function run--bat {
Write-host "run bat";
Start-Process -File "C:/t/w.bat" "i:/ o:/"
}
but i it not succes. need some expert help to resolve this .
Pass an argument list:
Start-Process C:\t\w.bat -ArgumentList 'i:\','o:\'
The comma operator builds arrays in PowerShell, so 'i:\','o:\' is a two-element array.
Start-Process will join the arguments with spaces in order to create the finalized command line. This means you could also pass both arguments as one string:
Start-Process C:\t\w.bat -ArgumentList 'i:\ o:\'
From w.bat's point of view there will be no difference.
To pass a value that contains spaces - such as a path - as a single argument, you need to wrap it in double quotes:
Start-Process C:\t\w.bat -ArgumentList '"i:\something\with spaces"','o:\'
Then w.bat will see two arguments:
%1 = "i:\something\with spaces" (and %~1 = i:\something\with spaces)
%2 = o:\
I am trying to deploy a site (basically a zip file) from my machine to a remote machine. I was testing the same before I implement the actual remote deployment and I was working to the msdeploy command line code using powershell.
Later I will configure this code in C# language and execute it that will automate the deployment.
Right now , I am facing the error called
$msdeploy = "C:\\Program Files\\IIS\\Microsoft Web Deploy V3\\msdeploy.exe"
$package = "C:\Deploy\Test\Test.zip"
$compname = "test_vm02"
$appname = "Default Web Site/Test"
$appvalue = "Test\"
$md = $("`"{0}`" -verb:sync -source:package=`"{1}`" -dest=auto,ComputerName=`"{2}`" -setParam=name=`"{3}`",value=`"{4}`" -allowUntrusted" -f $msdeploy, $package, $compname, $appname, $appvalue)
cmd.exe /C $md
This gives error saying that source does not support the parameter 'Default Web Site/Test'.Must be one of ()
I also replaced the default web site to IIS Web Application Name which in this case also did not work and threw the same error.
Any help is much appreciated!!
PowerShell's handling of quotes in arguments passed to external programs is fundamentally broken, but things get more complicated if there's another level of quoting involved, as in your indirect call to msdeploy.exe via cmd.exe.
There is usually no reason to call external programs via cmd /c; instead, call them directly from PowerShell, which, if the program name is quoted or given via a variable, requires prepending the command line with &, the call operator:
Note: The line-ending ` chars. are line continuations, used for readability only; ignore the broken syntax highlighting.
$package = 'C:\Deploy\Test\Test.zip'
$compname = 'test_vm02'
$appname = 'Default Web Site/Test'
# !! If a value ends in '\' you must *double* the '\' if the value
# !! ends up just before a " in the ultimate command line.
$appvalue = 'Test\\'
& "C:\Program Files\IIS\Microsoft Web Deploy V3\msdeploy.exe" `
-verb:sync `
-source:package=`"$package`" `
`-dest=auto,ComputerName=`"$compname`" `
`-setParam=name=`"$appname`",value=`"$appValue`" `
-allowUntrusted
Note the need to `-escape the - before the -dest and -setParam options, which is a workaround for the bug described in this GitHub issue.
Leaving the parameter names (e.g. -source:package) otherwise unquoted and enclosing their arguments in explicit, embedded quotes (`") ensures that the whole token is passed through looking something like -source:package="C:\Deploy\Test\Test.zip", which some programs, notably msiexec.exe and possibly also msdeploy.exe, require.
Caveat: If PowerShell's broken (re)quoting of arguments passed to external programs (see this answer) should ever get fixed (see this GitHub issue), this technique will break.
If you just used -source:package=$package and the value of $package contained embedded spaces, PowerShell would double-quote the whole token behind the scenes and pass something like
"-source:package=C:\Deploy 1\Test\Test.zip"
Programs such as msiexec.exe and msdeploy.exe should recognize this quoting style too, but unfortunately don't.
I've just tested this on PowerShell v1.0. Setup is as follows:
Id CommandLine
-- -----------
1 $msbuild = "C:\Windows\Microsoft.NET\Framework\v3.5\msbuild.exe"
4 $a = "C:\some\project\or\other\src\Solution.sln /target:Clean /target:Build"
.
This line fails with an unintuitive error message:
Id CommandLine
-- -----------
5 & $msbuild $a
.
This line fails because & expects the first argument to be the command itself.
Id CommandLine
-- -----------
10 & "$msbuild $a"
.
This line works:
Id CommandLine
-- -----------
16 cmd /c "$msbuild $a"
.
Please explain. I'm more interested in why the & syntax isn't working, than an MSBuild-specific workaround.
Ugh.
$collectionOfArgs = #("C:\some\project\or\other\src\Solution.sln",
"/target:Clean", "/target:Build")
& $msbuild $collectionOfArgs
This works. & takes a collection of arguments, so you must split up strings containing multiple arguments into a collection of string arguments.
The issues you are seeing results from PowerShell parsing arguments. In the first example, when PowerShell sees $a it passes it as a single parameter msbuild. We can see this using the echoargs utility from PSCX:.
PS> $a = "C:\some\project\or\other\src\Solution.sln /target:Clean /target:Build"
PS> & echoargs $a
Arg 0 is <C:\some\project\or\other\src\Solution.sln /target:Clean /target:Build>
The second example is even worse because you are telling powershell to invoke "$echoargs $a" as the command name and it isn't a valid command name.
The third line works because CMD.exe gets the expanded form of "$echoargs $a" as a single argument which is parses and executes:
You have a couple of options here. First I do it this way:
PS> & $msbuild C:\some\project\or\other\src\Solution.sln `
/target:Clean /target:Build
The other option is to use Invoke-Expression like so:
PS> Invoke-Expression "$msbuild $a"
In general I try to be very careful with Invoke-Expression particularly if any part of the string that gets invoked is provided by the user.
You can also try using the free Invoke-MsBuild powershell script/module. This essentially gives you an Invoke-MsBuild PowerShell cmdlet that you can call instead of trying to invoke the msbuild.exe manually yourself.
That works well for me:
PS> cmd.exe /c 'C:\Windows\Microsoft.NET\Framework\v3.5\msbuild.exe' /target:Clean /target:Build 'C:\some\project\or\other\src\Solution.sln'
My PowerShell script should start an external executable with specified parameters. I have two strings: The file name, and the arguments. This is what process starting APIs usually want from me. PowerShell however fails at it.
I need to keep the executable and arguments in a separate strings because these are configured elsewhere in my script. This question is just about using these strings to start the process. Also, my script needs to put a common base path in front of the executable.
This is the code:
$execFile = "SomeSetup.exe"
$params = "/norestart /verysilent"
& "$basePath\$execFile" $params | Out-Host
# Pipe to the console to wait for it to finish
This is the actual result (does not work with this program):
Process file name: "C:\My\Base path\SomeSetup.exe"
Process command line: "/norestart /verysilent"
This is what I'd expect to have (this would work):
Process file name: "C:\My\Base path\SomeSetup.exe"
Process command line: /norestart /verysilent
The problem is that the setup recognises the extra quotes and interprets the two arguments as one - and doesn't understand it.
I've seen Start-Process but it seems to require each parameter in a string[] which I don't have. Splitting these arguments seems like a complicated shell task, not something I'd do (reliably).
What could I do now? Should I use something like
& cmd /c "$execFile $params"
But what if $execFile contains spaces which can well happen and usually causes much more headache before you find it.
You can put your parameters in an array:
$params = "/norestart", "/verysilent"
& $basepath\$execFile $params
When you run a legacy command from Powershell it has to convert the powershell variables into a single string that is the legacy command line.
The program name is always enclosed in quotes.
Any parameters that contain a space character are enclosed in double
quotes (this is of course the source of your problem)
Each element of an array forms a separate argument.
So given:
$params = "/norestart /verysilent"
& "$basePath\$execFile" $params
Powershell will run the command:
"\somepath\SomeSetup.exe" "/norestart /verysilent"
The solution is to store separate arguments in an array:
$params = "/norestart","/verysilent"
& "$basePath\$execFile" $params
will run:
"\somepath\SomeSetup.exe" /norestart /verysilent
Or if you already have a single string:
$params = "/norestart /verysilent"
& "$basePath\$execFile" ($params -split ' ')
will work as well.
$execFile = "SomeSetup.exe"
$params = "/norestart /verysilent"
Invoke-Expression ($basePath + "\" + $execFile + " " +$params)
Try it this way:
& $execFile /norestart /verysilent
Bill
Just use single quotes:
$execFile = "SomeSetup.exe"
$params = "/norestart /verysilent"
& "'$basePath\$execFile' $params" | Out-Host
# Pipe to the console to wait for it to finish
Also I would use join-path instead of concatenating the two strings:
$path = Join-Path $basePath $execFile
& "$path $params" | out-host
all,
I am trying to run a command in Power Shell and I am told the file does not exist as it stands right now for the Power Shell code. If I do the same in DOS, it finds the file and executes correctly. The only difference is that there is an additional open and closed double quote around the file name. Can this be done in Power Shell the same way? If so, how can this be done as I am not familiar with Power Shell.
DOS:
IF EXISTS F:\lvcecstos.CSV F:\LaserVault\ContentExpress\ContentExpress.exe /CID:1 /CSV:<b>"F:\lvcecstos.CSV"</b> /ClearSubscription
Power Shell:
Invoke-Expression -Command "F:\LaserVault\ContentExpress\ContentExpress.exe /CID:1 /CSV:<b>F:\lvcecstos.csv</b> /ClearSubscription"
Thanks in advance for any suggestions. I am told by the Laservault engineers that created this software package that we use that the double quotes around the file name is required. Doesn't make sense to me as to why though, but this is something I am unable to get around.
You can add double quotes around the file path as follows:
Invoke-Expression -Command 'F:\LaserVault\ContentExpress\ContentExpress.exe /CID:1 /CSV:"F:\lvcecstos.csv" /ClearSubscription';
Notice how the command is wrapped in single quotes instead of double quotes.
Ultimately, it depends on how the ContentExpress.exe program is interpreting the file path, though. For all you know, it could be appending the valued passed to "CSV" to the "current working directory."
You can also use the Start-Process cmdlet, instead of Invoke-Expression or Invoke-Command.
$Program = 'F:\LaserVault\ContentExpress\ContentExpress.exe';
$ArgumentList = '/CID:1 /CSV:"F:\lvcecstos.csv" /ClearSubscription';
Start-Process -Wait -NoNewWindow -FilePath $Program -ArgumentList $ArgumentList;
If you have PowerShell v3 (which you should) you could use the "magic parameter" --% (see here).
& F:\LaserVault\ContentExpress\ContentExpress.exe --% /CID:1 /CSV:"F:\lvcecstos.csv" /ClearSubscription
Otherwise trying to preserve double quotes around arguments could become very, very painful. See for instance this answer to a similar question.
$lvcecstos = "F:\lvcecstos.CSV"
If(Test-Path $lvcecstos)
{
Invoke-Expression -Command "& F:\LaserVault\ContentExpress\ContentExpress.exe /CID:1 /CSV:$lvcecstos /ClearSubscription"
}
