Escape % in parameter passed to Powershell
msbuild, powershell
Solution
In batch files, the percent sign may be "escaped" by using a double percent sign ( %% ). So this will do the trick:
<Exec Command="powershell "& {. 'C:\test.ps1';Test -password '%25%25'}"" />
Problem
I have a MSBuild script that starts PowerShell to perform some work on remote computer so you have to pass password to create remote session, but there is issue - if password contains % character it is parsed wrong - % is missing (ex: pass%word -> password, '%' -> ''(nothing)). If I'm creating variable in PowerShell script $password = "pass%word" it works fine. I know % is foreach in PowerShell so I tried to escape it using ` - but it didn't helped. Also I can change password, but thats not an option (for now). So how can I solve this issue? MSBuild part ``` <Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="Test"> <Target Name="Test"> <!-- %25 - it's code for %--> <Exec Command="powershell "& {. 'C:\test.ps1';Test -password '`%25'}"" /> </Target> </Project> ``` test.ps1 ``` Function Test { param ( [string]$password = $(throw "Please specify password") ) Write-Host $password } ```
