Question

I am trying to make a simple script to set my gcc variables. as a .bat file.

the variable is set like this

$env:Path += ";C:\Users\Brett\Compilers\MinGW\bin"

this runs just fine when I type/paste it into power shell.

but when I paste into a script myscript.bat, and run it through powershell I get this error:

C:\Users\Brett\Compilers>"$env:Path += ";C:\Users\Brett\Compilers\MinGW\bin""
The filename, directory name, or volume label syntax is incorrect.
PS C:\Users\Scruffy\Compilers>

Answer 1

PowerShell is a seperate execution enviroment from with Windows Command Line (cmd.exe)

If you want to run powershell commands from a batch file you need to save the powershell script (.ps1) and pass it into powershell.exe as a command line argument.

Example:

powershell.exe -noexit c:\scripts\test.ps1
