I am trying to run an executable through powershell to run headless, to install a program onto a VM/LocalHost machine. I can get the wizard to open, but for whatever reason I cannot get it to run headless. Here is the cmd line that I run that works:
start /WAIT setup.exe /clone_wait /S /v" /qn"
This is my attempts in powershell
Start-Process .\setup.exe /S -Wait -PassThru
Start-Process .\setup.exe /S /v /qn -Wait -PassThru
Start-Process setup.exe -ArgumentList '/clone_wait /S /v /qn' -Wait
In the cmd line instance the application installs without issue - in the powershell instance the wizard opens and is on the first "Next" prompt. Any help would be appreciated!
I also attempted to add the additional parameters "/v" and "/qn" which return an error : Start-Process : A positional parameter cannot be found that accepts argument '/v'
The bottom attempt runs but it's not waiting for the installation to complete
You may be overthinking it. Remember that PowerShell is a shell. One of the purposes of a shell is to run commands that you type.
Thus: You don't need Start-Process. Just type the command to run and press Enter.
PS C:\> .\setup.exe /clone_wait /S /v /qn
Now if the executable (or script) you want to run contains spaces in the path or name, then use the call/invocation operator (&) and specify the quotes; for example:
PS C:\> & "\package files\setup.exe" /clone_wait /S /v /qn
(This behavior is the same no matter whether you are at the PowerShell prompt or if you put the command in a script.)
This worked for me. You need to quote the whole argumentlist, plus embed double quotes to pass what you want to /v.
start-process -wait SetupStata16.exe -ArgumentList '/s /v"/qb ADDLOCAL=core,StataMP64"'
Running the command normally and then using wait-process after might be a simpler alternative, if you're sure there's only one process with that name:
notepad
wait-process notepad
To follow-up to all that you have been given thus far. Running executables via PowerShell is a well-documented use case.
PowerShell: Running Executables
Solve Problems with External Command Lines in PowerShell
Top 5 tips for running external commands in Powershell
Using Windows PowerShell to run old command-line tools (and their
weirdest parameters)
So, from the first link provides more validation of what you've been given.
5. The Call Operator &
Why: Used to treat a string as a SINGLE command. Useful for dealing with spaces.
In PowerShell V2.0, if you are running 7z.exe (7-Zip.exe) or another command that starts with a number, you have to use the command invocation operator &.
The PowerShell V3.0 parser do it now smarter, in this case you don’t need the & anymore.
Details: Runs a command, script, or script block. The call operator, also known as the "invocation operator," lets you run commands that are stored in variables and represented by strings. Because the call operator does not parse the command, it cannot interpret command parameters
Example:
& 'C:\Program Files\Windows Media Player\wmplayer.exe' "c:\videos\my home video.avi" /fullscreen
Things can get tricky when an external command has a lot of parameters or there are spaces in the arguments or paths!
With spaces you have to nest Quotation marks and the result it is not always clear!
In this case it is better to separate everything like so:
$CMD = 'SuperApp.exe'
$arg1 = 'filename1'
$arg2 = '-someswitch'
$arg3 = 'C:\documents and settings\user\desktop\some other file.txt'
$arg4 = '-yetanotherswitch'
& $CMD $arg1 $arg2 $arg3 $arg4
# or same like that:
$AllArgs = #('filename1', '-someswitch', 'C:\documents and settings\user\desktop\some other file.txt', '-yetanotherswitch')
& 'SuperApp.exe' $AllArgs
6. cmd /c - Using the old cmd shell
** This method should no longer be used with V3
Why: Bypasses PowerShell and runs the command from a cmd shell. Often times used with a DIR which runs faster in the cmd shell than in PowerShell (NOTE: This was an issue with PowerShell v2 and its use of .Net 2.0, this is not an issue with V3).
Details: Opens a CMD prompt from within powershell and then executes the command and returns the text of that command. The /c tells CMD that it should terminate after the command has completed. There is little to no reason to use this with V3.
Example:
#runs DIR from a cmd shell, DIR in PowerShell is an alias to GCI. This will return the directory listing as a string but returns much faster than a GCI
cmd /c dir c:\windows
7. Start-Process (start/saps)
Why: Starts a process and returns the .Net process object Jump if -PassThru is provided. It also allows you to control the environment in which the process is started (user profile, output redirection etc). You can also use the Verb parameter (right click on a file, that list of actions) so that you can, for example, play a wav file.
Details: Executes a program returning the process object of the application. Allows you to control the action on a file (verb mentioned above) and control the environment in which the app is run. You also have the ability to wait on the process to end. You can also subscribe to the processes Exited event.
Example:
#starts a process, waits for it to finish and then checks the exit code.
$p = Start-Process ping -ArgumentList "invalidhost" -wait -NoNewWindow -PassThru
$p.HasExited
$p.ExitCode
#to find available Verbs use the following code.
$startExe = new-object System.Diagnostics.ProcessStartInfo -args PowerShell.exe
$startExe.verbs
Consider:
(Get-Content Rel_DDL.SQL) | ForEach-Object {
$_ -replace "SWIFT [\d\.]+", "SWIFT 2.4.0"
} | Set-Content Rel_DDL.SQL
The above PowerShell code replaces SWIFT 2.3.0 with SWIFT 2.4.0 in a SQL file, which when I run through PowerShell works fine.
I want to run the PowerShell command through Windows CMD, but I am getting errors.
You can use the Powershell.exe command in CMD Windows with the -command parameter. Did you try it?
-Command
Executes the specified commands (and any parameters) as though they were
typed at the Windows PowerShell command prompt, and then exits, unless
NoExit is specified. The value of Command can be "-", a string. or a
script block.
If the value of Command is "-", the command text is read from standard input.
If the value of Command is a script block, the script block must be enclosed in braces ({}).
You can specify a script block only when running PowerShell.exe in Windows PowerShell. The results of the script block are returned to the parent shell as deserialized XML objects, not live objects.
If the value of Command is a string, Command must be the last parameter in the command, because any characters typed after the command are interpreted as the command arguments.
To write a string that runs a Windows PowerShell command, use the format: "& {}" where the quotation marks indicate a string and the invoke operator (&) causes the command to be executed.
Use the powershell command in that .bat script. I would not write to the same file as used for the input. Yes, I know this works because Get-Content reads the entire file, but it is not a good practice.
powershell -NoProfile -Command "(Get-Content Rel_DDL.SQL) |" ^
"ForEach-Object { $_ -replace 'SWIFT [\d\.]+', 'SWIFT 2.4.0' } |" ^
"Out-File -FilePath Rel_DDL2.SQL -Encoding Default"
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"
}
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.
References : Powershell/Scripting/Start-Process
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.

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:

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.
For my tests I am using 'Start > Run' dialog (not the cmd.exe).
This works fine, and I get 9 in log.txt
powershell -Command 4+5 > c:\log.txt
But this does not work:
powershell -EncodedCommand IAA1ACsANwAgAA== > c:\log.txt
So how can I redirect output in this case?
Experimental code:
function Test
{
$cmd = { 5+7 }
$encodedCommand = EncodeCommand $cmd
StartProcess "powershell -Command $cmd > c:\log.txt"
StartProcess "powershell -EncodedCommand $encodedCommand > c:\log2.txt"
}
function StartProcess($commandLine)
{
Invoke-WMIMethod -path win32_process -name create -argumentList $commandLine
}
function EncodeCommand($expression)
{
$commandBytes = [System.Text.Encoding]::Unicode.GetBytes($expression)
[Convert]::ToBase64String($commandBytes)
}
The "Run" dialog doesn't seem like it provides redirection at all. According to this usenet post you only get redirection if you have a console. I wonder if the redirection parameter is being parsed by powershell.exe, which is choosing to redirect if it's not receiving encoded input? Sounds like a question for Raymond Chen.
Anyway, this works, at the expense of spawning an otherwise useless console:
cmd /c powershell -EncodedCommand IAA1ACsANwAgAA== > c:\ps.txt
The difference between those two commands is that the -Command parameter is greedy. It takes everything on the command line after it, while -EncodedCommand is not greedy. What the first command is really doing is:
powershell -Command "4+5 > c:\log.txt"
So the new PowerShell instance is handling the redirection. However, if you use the -EncodedCommand paramter, the new PowerShell instance does not see the redirection because you did not include it in the encoded command. This can be a bad thing if the environment calling PowerShell does not have redirection (like in a scheduled task).
So, as "crb" showed, you need to either encode the redirection into your command, or call PowerShell from an environment that can handle the redirection (like cmd, or another PowerShell instance).
I had to encode command together with redirection.
function Test
{
$cmd = { 5+7 }
$encodedCommand = EncodeCommand "$cmd > 'c:\log2.log'"
StartProcess "powershell -Command $cmd > c:\log.txt"
StartProcess "powershell -EncodedCommand $encodedCommand"
}
So this will write a sum 5+7 into c:\log2.log
powershell -EncodedCommand IAA1ACsANwAgACAAPgAgACcAYwA6AFwAbABvAGcAMgAuAGwAbwBnACcA
P.S.
crb suggested to use "cmd /c". But in this case the encoded script length will be constrained by the command line limitations
