I have an environment variable named GOPATH
. In old style command shell I could run the command %GOPATH%\bin\hello
like this:
Is there an equivalently simple command in Windows PowerShell?
I am not trying to print the environment variable. I am trying to USE it.
The variable is set correctly:
C:\WINDOWS\system32> echo $env:gopath
C:\per\go
Now I want to actually use this in a command line call, and it fails:
C:\WINDOWS\system32> $env:gopath\bin\hello
At line:1 char:12
+ $env:gopath\bin\hello
+ ~~~~~~~~~~
Unexpected token '\bin\hello' in expression or statement.
+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : UnexpectedToken
Use $env:[Variablename]
For example:
$env:Appdata
or
$env:COMPUTERNAME
using your example:
$env:GOPATH
To use this to execute a script use
& "$env:GOPATH\bin\hello"
One solution is to use start-process -NoNewWindow to run it.
C:\windows\system32> start-process -nonewwindow $env:gopath\bin\hello.exe
C:\windows\system32Hello, Go examples!

This is much more verbose obviously and puts the command prompt at an odd looking prompt: >

Just a big huge THANK YOU! Your are the only one I found talking about that:
"To use this to execute a script use"
