Suppress output in Python calls to executables

To fix the issue you can do If you have Python 2.4, you can use the subprocess module:
>>> import subprocess
>>> s = subprocess.Popen(['cowsay', 'hello'], \
      stderr=subprocess.STDOUT, stdout=subprocess.PIPE).communicate()[0]
>>> print s
 _______ 
< hello >
 ------- 
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

Commands executed in PowerShell with variables surrounded in quotes fail. Why?

seems to work fine So I was able to get around this by executing it in CMD.exe and doing string manipulations to get what I need.
$str = &cmd /c 'dfsradmin membership list /rgname:"blah blah"'
$str = &cmd /c "dfsradmin membership list /rgname:$blah"       # with vars

Suppress output from non-PowerShell commands?

I hope this helps . Out-Null works just fine with non-PowerShell commands. However, it doesn't suppress output on STDERR, only on STDOUT. If you want to suppress output on STDERR as well you have to redirect that file descriptor to STDOUT before piping the output into Out-Null:
hg st 2>&1 | Out-Null

How to run Linux/Ubuntu commands(not executables) from Nodejs

hop of those help? Environment variables only exist in memory and are local to a process. For any running process, only the process itself can make changes to the set of environment variables "belonging" to that process, but those changes will not propagate to existing child or parent processes.
In short: you cannot change an environment variable that will apply to all processes on your system (not even from a regular shell).
