Can I use variables in the PowerShell Replace method? - powershell

Question

My goal is to run a PowerShell command that will update the text in a markdown table.
My project structure looks like:
/root  
dashboardTable.md  
replace.ps1
dashboardTable.md:
App Name | Build Version | QA Version | Prod Version
------ | ------ | ------ | ------ |
ProjectName |0.0.0 | 0.0.0 | 0.0.0
replace.ps1
(Get-Content ./dashboardTable.md).replace('0.0.0', '0.0.1') | Set-Content './dashboardTable.md'
Running this command works and will change the markdown file to:
App Name | Build Version | QA Version | Prod Version
------ | ------ | ------ | ------ |
ProjectName |0.0.1 | 0.0.1 | 0.0.1
I am trying to set a variable that can be used in place of the hardcoded values in the replace method, for example:
$MyVariable = '0.0.0'
(Get-Content ./dashboardTable.md).replace($MyVariable, '0.0.1') | Set-Content './dashboardTable.md'
But this changes my markdown file to:
App Name | Build Version | QA Version | Prod Version
------ | ------ | ------ | ------ |
0.0.1 |0.0.0 | 0.0.0 | 0.0.0
I even tried to switch the replace values around and run the PowerShell command like:
$MyVariable = '0.0.1'
(Get-Content ./dashboardTable.md).replace('0.0.0', $MyVariable) | Set-Content './dashboardTable.md'
And it changes the markdown to:
App Name | Build Version | QA Version | Prod Version
------ | ------ | ------ | ------ |
ProjectName |ProjectName | ProjectName | ProjectName
Is it possible to use a variable like this?

Answer 1

I'm not sure why I was getting the results I was getting however, I do know there was an issue when I was calling the PowerShell script.
To fix the issue, when I want to run the script, I run this command in the PowerShell Integrated Terminal:
powershell -executionpolicy bypass ".\replace.ps1" and was able to get the expected results.
