I'm currently having a major issue with a python script. The script runs arbitrary commands through a handler to convert incorrect error reporting into correct error reporting. The

Solution 1:

Make sure you are using lists and no shell expansion:

subprocess.Popen(['command', 'argument1', 'argument2'], shell=False)

Solution 2:

A proper answer will need more information than that. What are you actually doing? How does it fail? Are you using the subprocess module? Are you passing a list of arguments and shell=False (or no shell argument) or are you actually invoking the shell?

Solution 3:

Try quoting the argument that contains the &

wget "http://foo.com/?bar=baz&baz=bar"

Is usually what has to be done in a Linux shell

Solution 4:

"escaping the ampersand with ^"

Are you sure ^ is an escape character to Windows? Shouldn't you use \?

Solution 5:

To answer my own question:

Quoting the actual command when passing the parameters as a list doesn't work correctly (command is first item of list) so to solve the issue I turned the list into a space separated string and passed that into subprocess instead.

Better solutions still welcomed.
