I am using team city 9.1.7 version on Windows 2012 server. As part of the build steps, I build a nodejs based application using command line. The output is bunch of Javascript and html files.
In the next step (after the build is over & output is generated), I want to perform following:
Take the current build number from team city and insert it into index.html (available in output folder) file. I want to add a meta tag which can tell me the build version.
In the same file (index.html), I want to perform string find and replace operations. I want to add time stamp to files.
Find this <script src="bundle.js"></script> and
replace with <script src="bundle.js?time=getTime()"></script>
will results in <script src="bundle.js?time=4324324324"></script>
Try the following
Add a PowerShell step and run the following as source code
$versionNumber = "%build.number%"
$filePath = "%teamcity.agent.work.dir%\path\file.txt"
(GC $filePath).Replace("<head>", "<head><meta http-equiv='X-Version-Number' content='$versionNumber'>").Replace("bundle.js", "bundle.js?time=getTime()") | Set-Content $filePath
This will read the file contents in and perform two replacements on them and then write back to the file.
Not sure what your file path is or what you want the header called, but you should be able to change this to suit your requirements.
Hope this helps
REVISION
To catch any exceptions, try wrapping the code in a try catch block
try {
(GC $filePath).Replace("<head>", "<head><meta http-equiv='X-Version-Number' content='$versionNumber'>").Replace("bundle.js", "bundle.js?time=getTime()") | Set-Content $filePath
}
catch [System.Exception] {
Write-Output $_
Exit 1
}
To break out of the cache you could use the version number as this will increment each build and thus be unique
try {
(GC $filePath).Replace("<head>", "<head><meta http-equiv='X-Version-Number' content='$versionNumber'>").Replace("bundle.js", "bundle.js?v=$versionNumber") | Set-Content $filePath
}
catch [System.Exception] {
Write-Output $_
Exit 1
}

Reference: Runspace for button event in powershell
https://www.foxdeploy.com/blog/part-v-powershell-guis-responsive-apps-with-progress-bars.html
So, I believe my issue is that PowerShell is unable to access the memory space of the file system, from within the memory block, of my thread, is there a way to solve this, to access the file system, from a multi-threaded application?
Back Story:
So, I run a program, that calls upon "code"/command, from the command prompt, (*.exe) (Robocopy) to copy files from a server, to a group of computers, at a time. We have a classroom environment, at my work, so I have my setup, in a way, that I have a folder, per room. I keep a list of all our addresses (static), for each room, in their perspective folders. We have an update, from our developers, that we need to push to all of the rooms. We need to run a slow push, as to not disturb the production environment. It's proprietary, so we can't use a/any typical solution(s), like Microsoft SCCM. So, I created a script to push to the rooms. while it does work, it's not a smooth operation. I'm not actually the one pushing the update, because of the slow process, of updating. I'm just trying to make a stable smooth-running package, for the person, who is going to be doing it. My code works, outside of the thread, (I) tested it, I know it works.
So how I came my conclusion of knowing, that my code works outside of the thread. (The picture) I followed the same setup, with my code, (A button click event inside of a thread, running the form). Placed the actual working code, (tried, and tested, before making a Thread, for the interface, after completing backend operation code testing.)
("Region Boe's Addition") referring to Boe Prox, (from the link)
In his, he is updating from a command line/powershell window, via a function run inside a thread. I'm running an event from a button, inside of a thread and trying to run a separate thread, for the click event(s). Outside of the thread. The event works fine, but inside, it doesn't work, at all..
Basic Code:
// Multi thread, thread for the $form, and thread for the event (as per referenced link)
$var = [PowerShell]::Create().AddScript({ button.Add_Click{
$var = [PowerShell]::Create().AddScript{<Thread><Robocopy></Thread>}
})
Needed the "Start-Process" -Wait command to allow for the listbox, to be updated in-between copies, to confirm installation, through each step in the loop.
$choice = $comboBox.SelectedItem
# $drive = Get-Location
if(!(Test-Path -PathType Container -Path "L:\$choice"))
{
# New-Item -ItemType "container" -Path . -Name $choice
New-Item -ItemType "Directory" -Path . -Name $choice
}
# $folder = $_
# Where is it being stored at?
[System.IO.File]::ReadLines("Y:\$choice\IPs.txt") | foreach {
ping -a -n 2 -w 2000 $_ | Out-Null
Test-Connection -Count 2 -TimeToLive 2 $_ | Out-Null
if($?)
{
RoboCopy /Log:"L:\$folder\$_.log" $source \\$_\c$\tools
RoboCopy /Log+:"L:\$folder\$folder-MovementLogs.log" $source \\$_\c$\tools
Start-Process -Wait "P:\psexec.exe" -ArgumentList "\\$_ -d -e -h -s cmd /c reg import C:\tools\dump.reg"
# Copy-Item -LiteralPath Y:\* -Destination \\$_\c$\tools
$listBox.Items.Add($_)
}
}
I am limited to PuTTY and WinSCP only.
I am trying to download log directories with log files. For example, I want to grab all log_files 6 days old or newer. log_dir2 and log_dir3 including the folders match the criteria, while log_dir1 and its files does not.
DIR/log_dir1/log_files % older than 6 days
DIR/log_dir2/log_files % meets criteria
DIR/log_dir3/log_files % meets criteria
My problem is that while the log_files of log_dir1 are not downloaded, the syntax I am currently using downloads the log_dir1 folder. Normally, not a big deal, but we are talking hundreds of log_dir folders (all empty as the files are older than 6 days). For reasons beyond my control, I cannot move or archive these old log directories with their log files.
My question is simply, how do I change my syntax to ignore folders that are older than 6 days as well as files.
get -filemask="*>6D" /DIR/* C:\temp
I have tried several different combinations of parameters and I have read the support page about Directory Masks and Path Masks. I cannot get any of them working (version issue?). Can anyone explain their syntax better than the help page. I will update tomorrow with the current version of WinSCP that I am using.
Time constraint in WinSCP file mask cannot be used for directories.
But you can prevent WinSCP from creating the empty folders. Use -rawtransfersettings switch with ExcludeEmptyDirectories setting.
get -rawtransfersettings ExcludeEmptyDirectories=1 -filemask="*>6D" /DIR/* C:\temp
This is the original answer, before WinSCP supported ExcludeEmptyDirectories. It might still be useful as a basis for implementations that have even more specific constraints.
You can implement this custom logic easily in PowerShell script with a use of WinSCP .NET assembly:
# Load WinSCP .NET assembly
Add-Type -Path "WinSCPnet.dll"
# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property #{
Protocol = [WinSCP.Protocol]::Sftp
HostName = "example.com"
UserName = "username"
Password = "password"
SshHostKeyFingerprint = "..."
}
$remotePath = "/remote/path"
$localPath = "C:\local\path"
$limit = (Get-Date).AddDays(-6)
$session = New-Object WinSCP.Session
# Connect
$session.Open($sessionOptions)
# Enumerate files to download
$fileInfos =
$session.EnumerateRemoteFiles(
$remotePath, $Null, [WinSCP.EnumerationOptions]::AllDirectories) |
Where-Object { $_.LastWriteTime -gt $limit }
foreach ($fileInfo in $fileInfos)
{
$localFilePath =
[WinSCP.RemotePath]::TranslateRemotePathToLocal(
$fileInfo.FullName, $remotePath, $localPath)
# If the corresponding local folder does not exist yet, create it
$localFileDir = Split-Path -Parent $localFilePath
if (!(Test-Path -Path $localFileDir))
{
Write-Host "Creating local directory $localFileDir..."
New-Item $localFileDir -ItemType directory | Out-Null
}
Write-Host "Downloading file $($fileInfo.FullName)..."
# Download file
$sourcePath = [WinSCP.RemotePath]::EscapeFileMask($fileInfo.FullName)
$transferResult = $session.GetFiles($sourcePath, $localFilePath)
# Did the download succeeded?
if (!$transferResult.IsSuccess)
{
# Print error (but continue with other files)
Write-Host ("Error downloading file ${remoteFilePath}: " +
$transferResult.Failures[0].Message)
}
}
$session.Dispose()
Write-Host "Done."
Run the script (download.ps1) like:
powershell.exe -ExecutionPolicy Unrestricted -File download.ps1
I was looking through Perforce : Prefill changelist description which is supposed to describe 1:1 how to create a form-out change trigger, which I did.
p4 triggers file
suffix form-out change "powershell S:/p4_template.ps1 %formfile%"
template file:
(Get-Content $args[0]) |
Foreach-Object {$_ -replace "<enter description here>", "template text"} |
Set-Content $args[0]
However, I'm constantly getting the following error message:
'suffix' validation failed:
Execution Failed: powershell -ExecutionPolicy Bypass -File
S:/p4template.ps1 /tmp/tmp.379055.140083088879040.130: No such file or directory
I did restart the perforce server as well (just because it was mentioned in that thread but looks like it doesn't really need to be restarted). From what I see, we want to have access to the tmp file and replace the text, but that tmp file /tmp/tmp.379055.140083088879040.130 doesn't seem to exist? I've checked %TEMP% and set it as well with an ENV var. Further i'm getting this message in p4v when I click refresh and it does a p4 change -o operation.
Answering for posterity: the issue here is that the trigger runs on the server, not the client, and presumably the No such file refers to either the powershell executable or the script not existing on the server.

I created a new Blazor PWA WebAssembly (last version default template) project and deployed it in a IIS in Windows Server to try PWA.
Installed the last .NET Core Hosting Bundle.
After publising it, I ran the script in the Microsoft Docs to rename dll files:
dir .\_framework\_bin | rename-item -NewName { $_.name -replace ".dll\b",".bin" } ((Get-Content .\_framework\blazor.boot.json -Raw) -replace '.dll"','.bin"') | Set-Content .\_framework\blazor.boot.json
And the serviceworker renaming code too:
((Get-Content .\service-worker-assets.js -Raw) -replace '.dll"','.bin"') | Set-Content .\service-worker-assets.js
Then I deleted the compressed files as the docs says:
wwwroot\service-worker-assets.js.br
wwwroot\service-worker-assets.js.gz
wwwroot\_framework\blazor.boot.json.br
wwwroot\_framework\blazor.boot.json.gz
But I am still getting an error when I load the app:
What Am I missing here?
I guess that it has to do with the hashes and the renaming thing but cant find any solution in the Blazor´s Github issues.
As a result of your modifications to the blazor.boot.json file, the integrity checks fails. service-worker-assets.js contains a list of files and their integrity hashes which are calculated at the time of publish.
You can manually recalculate the hashes using Bash/PowerShell, since you're using IIS, I'll provide the PowerShell script I used for a similar issue:
# make sure you're in the wwwroot folder of the published application
$JsFileContent = Get-Content -Path service-worker-assets.js -Raw
# remove JavaScript from contents so it can be interpreted as JSON
$Json = $JsFileContent.Replace("self.assetsManifest = ", "").Replace(";", "") | ConvertFrom-Json
# grab the assets JSON array
$Assets = $Json.assets
foreach ($Asset in $Assets) {
$OldHash = $Asset.hash
$Path = $Asset.url
$Signature = Get-FileHash -Path $Path -Algorithm SHA256
$SignatureBytes = [byte[]] -split ($Signature.Hash -replace '..', '0x$& ')
$SignatureBase64 = [System.Convert]::ToBase64String($SignatureBytes)
$NewHash = "sha256-$SignatureBase64"
If ($OldHash -ne $NewHash) {
Write-Host "Updating hash for $Path from $OldHash to $NewHash"
# slashes are escaped in the js-file, but PowerShell unescapes them automatically,
# we need to re-escape them
$OldHash = $OldHash.Replace("/", "\/")
$NewHash = $NewHash.Replace("/", "\/")
$JsFileContent = $JsFileContent.Replace("""$OldHash""", """$NewHash""")
}
}
Set-Content -Path service-worker-assets.js -Value $JsFileContent -NoNewline
This script iterates over all files listed inside of service-worker-assets.js, calculates the new hash for each file and updates the hash in the JavaScript file if it's different.
You have to execute the script with the published wwwroot folder as the current working directory.
I described this in more detail on my blog: Fix Blazor WebAssembly PWA integrity checks
I need a script that reads the last modified date of a file and by whom it was modified and outputs to excel. I found a script that changes the modification date.
$a = get-date
$b = Get-ChildItem "C:\Intel" -recurse | ? { !$_.psiscontainer }
foreach ($i in $b)
{
$i.LastWriteTime = $a
}
$b
You can easily get the LastWriteTime by checking the LastWriteTime proprty of a file.
get-childitem * | select FullName,LastWriteTime,Owner
You can check the owner of a file which may or may not be the last person to modify depending on the file type. Some office files will change owner to the last person to write to them but I don't know that this is reliable.
get-childitem * | ForEach-Object {get-acl $_ | select owner}
NTFS doesn't log the last person to modify a file. You can either turn on auditing and check the system audit eventlog or look into the filesystemwatcher class and build a custom script that watches for changes to a folder. (Warning: this may cause performance issues.)
