The following two inline yaml-pipeline powershell scripts:
- pwsh: (get-content -path $(versionHeader)) | foreach-object {$_ -replace "2.0.0.0", '$(major).$(minor).$(patch).0'} | set-content -path $(versionHeader)
displayName: 'Update build number in header file'
- pwsh: (get-content -path $(versionHeader)) | foreach-object {$_ -replace "20200101000000", (get-date -f 'yyyyMMddhhmmss')} | set-content -path $(versionHeader)
displayName: 'Update date in header file'
are meant to take these two lines
[assembly: MyApp.Net.Attributes.AssemblyVersion("2.0.0.0")]
[assembly: MyApp.Net.Attributes.BuildDateAttribute("20200101000000")]
and turn them into these two lines (i.e. put new values in the quotes)
[assembly: MyApp.Net.Attributes.AssemblyVersion("2.0.185.0")]
[assembly: MyApp.Net.Attributes.BuildDateAttribute("20200724013502")]
(The replacement values vary)
And either script works fine by itself. But when I try to use both scripts, one after the other, the second value comes out messed up.
[assembly: MyApp.Net.Attributes.AssemblyVersion("2.0.209.0")] // correct
[assembly: MyApp.Net.Attributes.BuildDateAttribute("202.0.209.000000")] // ?????
Obviously they are somehow interfering with each other but I don't know how. Can someone tell me what I'm doing wrong?
The problem is in powershell's -replace - it interprets wildcards, and it happens that 20200101000000 matches 2.0.0.0:
PS> "20200101000000" -replace "2.0.0.0", "zzzzzz"
20zzzzzz00000

PowerShell newbie trying to figure out how to pull SQL row with multiple values comma separated into PowerShell array to be used in Get-ChildItem -exclude.
Please note I have the SQL portion working to where I can pull the values into PowerShell, but no matter what I have tried when I try to pass it to the -exclude option it thinks its just one name, versus comma separated names. I need help understanding how to pass the SQL row values into an array like this so it can be used properly with -exclude

Thanks for any help you can provide.

If you have a string in your $row.ExcludeFolders variable that reliably includes commas, you can use similar to the following to create an array:
You might then be able to pass the array as the -Exclude value
I am trying to make a PowerShell script that will search a folder for a filename that contains a certain file-mask. All files in the folder will have format like *yyyyMd*.txt.
I have made a script:
[String]$date = $(get-date -format yyyyMd)
$date1 = $date.ToString
Get-ChildItem C:\Users\pelam\Desktop\DOM | Where-Object {$_.Name -like '*$date1*'}
But this does not seem to work..
Can anyone help? It seems the problem is that the date variable is not correct because when I hard code something like below, it works:
Get-ChildItem C:\Users\pelam\Desktop\DOM | Where-Object {$_.Name -like '*20141013*'}
You can simplify this by just using regex with the -match operator:
Get-ChildItem C:\Users\pelam\Desktop\DOM | Where-Object {$_ -match (Get-Date -format yyyyMMdd)}
And if you are on V3 or higher, you can further simplify to:
Get-ChildItem C:\Users\pelam\Desktop\DOM | Where Name -match (Get-Date -format yyyyMMdd)
I have a section of a script here where I am importing a CSV but trying to only select records where AppName does not contain "Security"
Here is what I have but it doesn't seem to be working; the records I am trying to omit still appear.
$file2 = import-csv -Path "$UpdatePath\$($todaydate).csv" | where {$_.AppName -notcontains "Security"} | Select-Object AppName
Any suggestions greatly appreciated
Thanks
$file2 = import-csv -Path "$UpdatePath\$($todaydate).csv" | where {$_.AppName -notlike "*Security*"} | Select-Object AppName
-notlike will do this, but I also added asterisks which are a wildcard character in the like operators.
-contains is actually for arrays (think collections of values).

I am sure this might have been asked a million times before. I am very new to Power Shell and would like to ask if I am doing this right.
In the directory, we have many files types. What I am trying to accomplish is to move only PDF files that are older than one month. To not even touch the other file extensions. The extensions in the folder are:
pdf, xml, csv
I have searched the forums prior to asking. This is what I have so far.
get-childitem -path \\server\folder -include "*.pdf" -exclude "*.xml,*.csv" | where-object {$_.LastWriteTime -gt (get-date).AddDays(-31)} | move-item -destination \\server\folder\folder2
One question though, how would you handle an exclude if there is no file extension?
Thanks for your time and patience with this noob!
There is no need to use "where" to test the extension as get-childitem does this for you. Although I would use the filter parameter (2nd positional parameter) in the case of a single extension to search for e.g.:
$date = (get-date).AddDays(-31)
get-childitem \\server\folder *.pdf | where-object {$_.LastWriteTime -gt $date} |
move-item -destination \\server\folder\folder2
Btw using the filter parameter is also faster which maybe important when searching a network share.
One way is to add $_.Extension -eq ".pdf" to your where-object block so that you only grab those extensions.
get-childitem -path \\server\folder | where-object {
$_.extension -eq ".pdf" -and ($_.LastWriteTime -gt (get-date).AddDays(-31))} | move-item -destination C:\test\test
Also, if you want files older than one month, your date comparison needs to be -lt and not -gt
get-childitem -path \\server\folder | where-object {
$_.extension -eq ".pdf" -and ($_.LastWriteTime -lt (get-date).AddDays(-31))} | move-item -destination C:\test\test
Another way to do this is to specify the -Name flag and use wildcard for filename:
get-childitem -path \\server\folder -name "*.pdf" | where-object {$_.LastWriteTime -gt (get-date).AddDays(-31)} | move-item -destination \\server\folder\folder2
I am not sure to understand your last question, but if you have pdf files with no extension, see this discussion.
I think something like that can help you. The file.exe (download) showing the mime-type of the files, which is something like PDF document, version 1.6, depending the pdf file version.
gci . | ? { (file.exe -b $_) -match "pdf" }
I am using a Find and Replace script found on StackOverflow.
Get-Content test.txt | `
ForEach-Object { $_ -replace "foo", "bar" } | `
Set-Content test2.txt
and as long as i am searching for foo and want to replace it with bar this works great.
My problem is that I want to replace ID="123456789" where the numbers are different every time. So the only thing i know for sure is that i want to search for "ID=" and the rest is variable. When i use my good friend to find a answer to this question i don't get anything because the word variable is in it.
The first argument of the -replace opeartor is a regex, so:
Get-Content test.txt |
ForEach-Object { $_ -replace "ID=\d+", "bar" } |
Set-Content test2.txt
Also, the -replace operator will work just as well on an array, so unless your file is really large you can also do this:
(Get-Content test.txt) -replace "ID=\d+", "bar" | Set-Content test2.txt
