||||
Install PowerShell on Windows, Linux or macOS.
|
||||
.DESCRIPTION
|
||||
By default, the latest PowerShell release package will be installed.
|
||||
If '-Daily' is specified, then the latest PowerShell daily package will be installed.
|
||||
.Parameter Destination
|
||||
The destination path to install PowerShell to.
|
||||
.Parameter Daily
|
||||
Install PowerShell from the daily build.
|
||||
Note that the 'PackageManagement' module is required to install a daily package.
|
||||
.Parameter DoNotOverwrite
|
||||
Do not overwrite the destination folder if it already exists.
|
||||
.Parameter AddToPath
|
||||
On Windows, add the absolute destination path to the 'User' scope environment variable 'Path';
|
||||
On Linux, make the symlink '/usr/bin/pwsh' points to "$Destination/pwsh";
|
||||
On MacOS, make the symlink '/usr/local/bin/pwsh' points to "$Destination/pwsh".
|
||||
.EXAMPLE
|
||||
Install the daily build
|
||||
.\install-powershell.ps1 -Daily
