Re: Python question
How, in Python, can I execute a string as a shell command? You should use the 'call' function of the 'subprocess' module. You can either pass it a string with the full command or a list of strings comprising the command (like execv in libc). You must pass the 'shell=True' option if you are passing the full string; otherwise it can be omitted. import subprocess subprocess.call(ls -l /home/rms, shell=True) subprocess.call([ls, -l, /home/rms]) -brandon -- Brandon Invergo http://brandon.invergo.net pgpihniyntL0h.pgp Description: PGP signature ___ gnu-misc-discuss mailing list gnu-misc-discuss@gnu.org https://lists.gnu.org/mailman/listinfo/gnu-misc-discuss

Re: Python question
* Richard Stallman: How, in Python, can I execute a string as a shell command? This is often an extremely bad idea because it results in shell command injection vulnerabilities. Instead of os.system(), use the subprocess module, which keeps the argument list separate and does not involve the shell (except when you specify the shell=True argument): https://docs.python.org/2/library/subprocess.html You still need to take care of separating options and user-supplied non-option argument. With GNU getopt, the -- separate does the trick. ___ gnu-misc-discuss mailing list gnu-misc-discuss@gnu.org https://lists.gnu.org/mailman/listinfo/gnu-misc-discuss
