For SSH specifically (ssh user@host "command with args") I've written this workaround pseudoshell that makes it easy to pass your argument vector to execve unmolested.

Note that at least in python, you can use "shlex.quote" instead - it's in stdlib and does not need any extra tools.

    >>> import subprocess
    >>> import shlex
    >>> subprocess.run(['ssh', 'host', shlex.join(['ls', '-la', 'a filename with spaces'])])
    ls: cannot access 'a filename with spaces': No such file or directory

works nested, too

    >>> layer2 = ['ls', '-la', 'a filename with spaces']
    >>> layer1 = ['ssh', 'host1', shlex.join(layer2)]
    >>> layer0 = ['ssh', 'host0', shlex.join(layer1)]
    >>> subprocess.run(layer0)

(I am not sure if Rust has equivalent, but if it does not, it's probably easy to implement.. Python version is only a few lines long)

Wrong! SSH is very much the worst: it uses the user's login shell, not sh -c. So if the user's login shell isn't POSIX compatible, it still fails!

   >>> subprocess.run(["fish", "-c", shlex.join(["echo", "this isn\\'t working"])])
   fish: Unexpected end of string, quotes are not balanced
   echo 'this isn\'"'"'t working'

Not in the standard library, but there are packages.

This just confirms my habit of switching to python as soon as a shell script reaches any level of complexity
