I have a powershell script that generates a report, and I have connected it to an io.filesystemwatcher. I am trying to improve the error handling capability. I already have the report generation function (which only takes in a filepath) within a try-catch loop that basically kills word, excel and powerpoint and tries again if it fails. This seems to work well but I want to embed in that another try-catch loop that will restart the computer and generate the report after reboot if it fails a second consecutive time.
I decided to try and modify the registry after reading this article: https://cmatskas.com/configure-a-runonce-task-on-windows/
my plan would be, within the second try-catch loop I will create a textfile called RecoveredPath.txt with the file path being its only contents, and then add something like:
Set-ItemProperty "HKLMU:\Software\Microsoft\Windows\CurrentVersion\RunOnce" -Name '!RecoverReport' -Value "C:\...EmergencyRecovery.bat"
Before rebooting. Within the batch file I have:
set /p RecoveredDir=<RecoveredPath.txt
powershell.exe -File C:\...Report.ps1 %RecoveredDir%
When I try to run the batch script, it doesn't yield any errors but doesn't seem to do anything. I tried adding in an echo statement and it is storing the value of the text file as a variable but doesn't seem to be passing it to powershell correctly. I also tried adding -Path %RecoveredDir% but that yielded an error (the param in report.ps1 is named $Path).
What am I doing incorrectly?
One potential problem is that not enclosing %RecoveredDir% in "..." would break with paths containing spaces and other special chars.
However, the bigger problem is that using mere file name RecoveredPath.txt means that the file is looked for in whatever the current directory happens to be.
In a comment your state that both the batch file and input file RecoveredPath.txt are located in your desktop folder.
However, it is not the batch file's location that matters, it's the process' current directory - and that is most likely not your desktop when your batch file auto-runs on startup.
Given that the batch file and the input file are in the same folder and that you can refer to a batch file's full folder path with %~dp0 (which includes a trailing \), modify your batch file to look as follows:
set /p RecoveredDir=<"%~dp0RecoveredPath.txt"
powershell.exe -File C:\...Report.ps1 "%RecoveredDir%"

I use the video transcoding tools made by Don Melton over on GitHub to compress self filmed videos. Now I would like to automate this task by using a PowerShell script to loop over the contents of a folder as input arguments for the tool and have the output put into a seperate folder. My problem is that the tool is written in a way that it has no option to provide an output location, instead it always places the output files in the directory where it is called in. So when I cd into an "output" directory "next to" the one where my input files are, I then can call
other-transcode ../input/file.mp4
and the output file of the same name as the input file will be placed in the output directory.
Now when I want to use the command in a script, how do I tell PowerShell to run the command as if it was typed manually into a shell that was in the output directory at the moment?
For context, this is my end goal, but I think it is easier to split the complicated question into multiple ones.
Ultimately, I want to be able to call my PS script from VBA (Excel), but the easiest way to do that seems to be with system batch commands - so I'm testing my script with a BAT file.
The script returns a text file with the contents of a webpage, sans HTML tags. It works fine called alone with default parameters; it worked fine with no spaces in the output path parameter, but I've had no luck using a path that includes a space.
PS1 script, boiled down:
param ( [string]$outputPathName="" )
$outputPathName | Out-File "D:\Documents\Google Drive\out.txt"
BAT file to test it:
powershell.exe '"D:\Documents\Google Drive\GetWebPage.ps1"' -outputPathName '"D:\Documents\Google Drive\out.txt"'
I get the error message "Unexpected token '-outputPathName' in expression or statement." (I also get a similar error for the argument, but if the parameter name were recognized I might be able to get past this.)
How can I pass a named argument in from BAT script file to PS1 script file (with spaces in the path and argument)?
I am currently trying to write a batch program that installs a module named SetConsolePath.psm1 at the correct location. I am a beginner with Batch and I have absolutely no powershell experience.
Through the internet, I have learned how to display PSModulePath with powershell -command "echo $env:PSModulePath.
How can I, via .bat file, move SetConsolePath.psm1 from the desktop to the location displayed by powershell -command "echo $env:PSModulePath?
Thank you in advance, and I apologize for my lack of experience.
Before I answer, I must out that you do not want to copy PowerShell module files directly to the path pointed by PsModulePath. You really want to create a folder inside PSModulePath and copy the files there instead.
The prefix env in a Powershell variable indicates an environment variable. $env:PSModulePath is actually referring to the PSMODULEPATH environment variable. On the command line, and in batch files, environment variables can be displayed by placing the name between percent symbols. (In fact, you could have displayed this value by typing echo %PSMODULEPATH% instead.)
To reference the desktop folder, have a look at this answer, which shows you how to use another environment variable, USERPROFILE.
Therefore, to copy the file from the desktop directory to the path specified in PSModulePath, you would do this:
COPY "%USERPROFILE%\Desktop\SetConsolePath.psm1" "%PSMODULEPATH%"
And, as I warned earlier, you really should copy the file to a folder underneath PsModulePath. So what you really want is:
IF NOT EXIST "%PSMODULEPATH%\MyNewFolder" MKDIR "%PSMODULEPATH%\MyNewFolder"
COPY "%USERPROFILE%\Desktop\SetConsolePath.psm1" "%PSMODULEPATH%\MyNewFolder"
I'm writing a batch script that, among other things, opens a macro enabled excel file (.xlsm):
2>nul (
>>%CSF% echo off
) && (start "cmdTitle" /B excel %CSF% /e /automation) || (echo could not open)
%CSF% is the variable referring to a full path to the excel file i.e. "C:\test\testfile.xlsm" (including the quotes for cases where there may be spaces in the directory / filename)
This code checks if the file is locked for editing, then if not it opens the file (start command) otherwise echos could not open.
If I open the file from windows explorer or run just the following in a batch script the file opens fine.
set CSF="C:\Test Folder\Test.xlsm"
start "cmdTitle" /B excel %CSF% /e /automation
However, running the batch file when checking for a locked file always causes excel to say, "Excel found unreadable content in 'filename.xlsm' Do you want to recover the contents of this workbook?" which removes the macros from the file.
EDIT: In addition to the file not opening correctly, any excel add-ins that do something upon excel opening, for example, removing and recreating a command bar also fail to load: "Addin.xla cannot be accessed"
What is causing the difference in behavior between running the command alone and in redirection?
TIA
Examine the end of the file in a hex viewer and see what, if anything, is appended to the end.
Your code as posted works fine (echoing the excel command too). Some other code is likely to be the problem.
I am doing a batch scripting assignment where I have to call one script from inside another. I need the script to run the second script no matter where my lecturer saves these scripts. How would I do this. Is there some way to find the path of script inside the script and use that to execute the file. Any help would be great. I think I need to use %'s but i'm not sure.
The name of the script is Hello World.bat.
How would I copy Hello World.bat to the C:\ if I don't know which directory the lecturer has placed it in. what command/s would I use so that the copy would work regardless of the scripts location.
I don't see the "DOS" tag, but I'll assume that it is for now. If you want the entire path, you can get it by doing this:
echo %cd%
If you want just the last folder, this works (inside a .bat file):
for %%* in (.) do #echo %%~n*
Note that from the command line, the above command will work with single %'s:
for %* in (.) do #echo %~n*
If the script you are executing is calling other scripts in the SAME folder location, you can prefix the path statement with "%~dp0" or "%~dps0" but do not put a backslash between that and the name of the script you are calling. In other words, if script1.bat is calling script2.bat in the same folder, the statement in script1.bat would refer to "%~dp0script2.bat"
sorry about batch files, am not familiar, but in nix shell, there is the locate command which can return the path of the file , if you know the filename exactly and the name is unique.
like
name=$(locate filname)
