I've been doing a few systems administration tasks with Python recently, and shell command invocation directly via the subprocess module is annoyingly clunky (even with the new convenience APIs).
Since subprocess needs to avoid the shell by default for security reasons, I suggest we add the following simple helper functions to shutil:
def call(cmd, *args, **kwds):
if args or kwds:
cmd = cmd.format(*args, **kwds)
return subprocess.call(cmd, shell=True)
def check_call(cmd, *args, **kwds):
if args or kwds:
cmd = cmd.format(*args, **kwds)
return subprocess.check_call(cmd, shell=True)
def check_output(cmd, *args, **kwds):
if args or kwds:
cmd = cmd.format(*args, **kwds)
return subprocess.check_output(cmd, shell=True)

Of course, even if others agree in principle, documentation and tests are still needed before this change can go anywhere. |
