If args is a sequence, the first item specifies the command string, andДЄny additional items will be treated as additional arguments to the shell Includes, for example, quoting or backslash escaping filenames with spaces in This means that the string must beДЇormatted exactly as it would be when typed at the shell prompt. On Unix, with shell=True: If args is a string, it specifies the command Used in the shell (such as filenames containing spaces or the echo command List elements, while arguments that need quoting or backslash escaping when

Note in particular that options (such as -input) and arguments (suchДЄs eggs.txt) that are separated by whitespace in the shell go in separate split ( command_line ) > print args > p = subprocess. > import shlex, subprocess > command_line = raw_input () /bin/vikings -input eggs.txt -output 'spam spam.txt' -cmd 'echo '$MONEY'' > args = shlex. Or path of the program to execute this will only work if the program is If a string is specified for args, it will be used as the name Os.execvp() to execute the child program. On Unix, with shell=False (default): In this case, the Popen class uses

Name for the executing program in utilities such as ps. Is still treated by most programs as the command name, which can then beДifferent from the actual executable name. When executable is given, the first item in the args sequence To execute is normally the first item in the args sequence or the string ifДЄ string is given, but can be explicitly set by using the executableДЄrgument. Popen ( args, bufsize=0, executable=None, stdin=None, stdout=None, stderr=None, preexec_fn=None, close_fds=False, shell=False, cwd=None, env=None, universal_newlines=False, startupinfo=None, creationflags=0 ) В¶ДЄrgs should be a string, or a sequence of program arguments. This module defines one class called Popen: class subprocess.
