This module -intends to replace several other, older modules and functions, like: - -os.system -os.spawn* -os.popen* -popen2.* -commands.* - -Information about how the subprocess module can be used to replace these -modules and functions can be found below. - - - -Using the subprocess module -=========================== -This module defines one class called Popen: - -class 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): - - -Arguments are: - -args should be a string, or a sequence of program arguments. The -program to execute is normally the first item in the args sequence or -string, but can be explicitly set by using the executable argument. - -On UNIX, with shell=False (default): In this case, the Popen class -uses os.execvp() to execute the child program. args should normally -be a sequence. A string will be treated as a sequence with the string -as the only item (the program to execute). - -On UNIX, with shell=True: If args is a string, it specifies the -command string to execute through the shell. If args is a sequence, -the first item specifies the command string, and any additional items -will be treated as additional shell arguments. - -On Windows: the Popen class uses CreateProcess() to execute the child -program, which operates on strings. If args is a sequence, it will be -converted to a string using the list2cmdline method. Please note that -not all MS Windows applications interpret the command line the same -way: The list2cmdline is designed for applications using the same -rules as the MS C runtime. - -bufsize, if given, has the same meaning as the corresponding argument -to the built-in open() function: 0 means unbuffered, 1 means line -buffered, any other positive value means use a buffer of -(approximately) that size. A negative bufsize means to use the system -default, which usually means fully buffered. The default value for -bufsize is 0 (unbuffered). - -stdin, stdout and stderr specify the executed programs' standard -input, standard output and standard error file handles, respectively. -Valid values are PIPE, an existing file descriptor (a positive -integer), an existing file object, and None. PIPE indicates that a -new pipe to the child should be created. With None, no redirection -will occur; the child's file handles will be inherited from the -parent. Additionally, stderr can be STDOUT, which indicates that the -stderr data from the applications should be captured into the same -file handle as for stdout. - -If preexec_fn is set to a callable object, this object will be called -in the child process just before the child is executed. - -If close_fds is true, all file descriptors except 0, 1 and 2 will be -closed before the child process is executed. - -if shell is true, the specified command will be executed through the -shell. - -If cwd is not None, the current directory will be changed to cwd -before the child is executed. - -If env is not None, it defines the environment variables for the new -process. - -If universal_newlines is true, the file objects stdout and stderr are -opened as a text files, but lines may be terminated by any of '\n', -the Unix end-of-line convention, '\r', the Macintosh convention or -'\r\n', the Windows convention. All of these external representations -are seen as '\n' by the Python program. Note: This feature is only -available if Python is built with universal newline support (the -default). Also, the newlines attribute of the file objects stdout, -stdin and stderr are not updated by the communicate() method. - -The startupinfo and creationflags, if given, will be passed to the -underlying CreateProcess() function. They can specify things such as -appearance of the main window and priority for the new process. -(Windows only) - - -This module also defines two shortcut functions: - -call(*args, **kwargs): - Run command with arguments. Wait for command to complete, then - return the returncode attribute. - - The arguments are the same as for the Popen constructor. Example: - - retcode = call(["ls", "-l"]) - - -Exceptions ----------- -Exceptions raised in the child process, before the new program has -started to execute, will be re-raised in the parent. Additionally, -the exception object will have one extra attribute called -'child_traceback', which is a string containing traceback information -from the childs point of view. - -The most common exception raised is OSError. This occurs, for -example, when trying to execute a non-existent file. Applications -should prepare for OSErrors. - -A ValueError will be raised if Popen is called with invalid arguments. - - -Security --------- -Unlike some other popen functions, this implementation will never call -/bin/sh implicitly. This means that all characters, including shell -metacharacters, can safely be passed to child processes. - - -Popen objects -============= -Instances of the Popen class have the following methods: - -poll() - Check if child process has terminated. Returns returncode - attribute. - -wait() - Wait for child process to terminate. Returns returncode attribute. - -communicate(input=None) - Interact with process: Send data to stdin. Read data from stdout - and stderr, until end-of-file is reached. Wait for process to - terminate. The optional stdin argument should be a string to be - sent to the child process, or None, if no data should be sent to - the child. - - communicate() returns a tuple (stdout, stderr). - - Note: The data read is buffered in memory, so do not use this - method if the data size is large or unlimited. - -The following attributes are also available: - -stdin - If the stdin argument is PIPE, this attribute is a file object - that provides input to the child process. Otherwise, it is None. - -stdout - If the stdout argument is PIPE, this attribute is a file object - that provides output from the child process. Otherwise, it is - None. - -stderr - If the stderr argument is PIPE, this attribute is file object that - provides error output from the child process. Otherwise, it is - None. - -pid - The process ID of the child process. - -returncode - The child return code. A None value indicates that the process - hasn't terminated yet. A negative value -N indicates that the - child was terminated by signal N (UNIX only). - - -Replacing older functions with the subprocess module -==================================================== -In this section, "a ==> b" means that b can be used as a replacement -for a. - -Note: All functions in this section fail (more or less) silently if -the executed program cannot be found; this module raises an OSError -exception. - -In the following examples, we assume that the subprocess module is -imported with "from subprocess import *". - - -Replacing /bin/sh shell backquote ---------------------------------- -output=`mycmd myarg` -==> -output = Popen(["mycmd", "myarg"], stdout=PIPE).communicate()[0] - - -Replacing shell pipe line -------------------------- -output=`dmesg | grep hda` -==> -p1 = Popen(["dmesg"], stdout=PIPE) -p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE) -output = p2.communicate()[0] - - -Replacing os.system() ---------------------- -sts = os.system("mycmd" + " myarg") -==> -p = Popen("mycmd" + " myarg", shell=True) -sts = os.waitpid(p.pid, 0) - -Note: - -* Calling the program through the shell is usually not required. - -* It's easier to look at the returncode attribute than the - exitstatus. - -A more real-world example would look like this: - -try: - retcode = call("mycmd" + " myarg", shell=True) - if retcode < 0: - print >>sys.stderr, "Child was terminated by signal", -retcode - else: - print >>sys.stderr, "Child returned", retcode -except OSError, e: - print >>sys.stderr, "Execution failed:", e - - -Replacing os.spawn* -------------------- -P_NOWAIT example: - -pid = os.spawnlp(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg") -==> -pid = Popen(["/bin/mycmd", "myarg"]).pid - - -P_WAIT example: - -retcode = os.spawnlp(os.P_WAIT, "/bin/mycmd", "mycmd", "myarg") -==> -retcode = call(["/bin/mycmd", "myarg"]) - - -Vector example: - -os.spawnvp(os.P_NOWAIT, path, args) -==> -Popen([path] + args[1:]) - - -Environment example: - -os.spawnlpe(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg", env) -==> -Popen(["/bin/mycmd", "myarg"], env={"PATH": "/usr/bin"}) - - -Replacing os.popen* -------------------- -pipe = os.popen(cmd, mode='r', bufsize) -==> -pipe = Popen(cmd, shell=True, bufsize=bufsize, stdout=PIPE).stdout - -pipe = os.popen(cmd, mode='w', bufsize) -==> -pipe = Popen(cmd, shell=True, bufsize=bufsize, stdin=PIPE).stdin - - -(child_stdin, child_stdout) = os.popen2(cmd, mode, bufsize) -==> -p = Popen(cmd, shell=True, bufsize=bufsize, - stdin=PIPE, stdout=PIPE, close_fds=True) -(child_stdin, child_stdout) = (p.stdin, p.stdout) - - -(child_stdin, - child_stdout, - child_stderr) = os.popen3(cmd, mode, bufsize) -==> -p = Popen(cmd, shell=True, bufsize=bufsize, - stdin=PIPE, stdout=PIPE, stderr=PIPE, close_fds=True) -(child_stdin, - child_stdout, - child_stderr) = (p.stdin, p.stdout, p.stderr) - - -(child_stdin, child_stdout_and_stderr) = os.popen4(cmd, mode, bufsize) -==> -p = Popen(cmd, shell=True, bufsize=bufsize, - stdin=PIPE, stdout=PIPE, stderr=STDOUT, close_fds=True) -(child_stdin, child_stdout_and_stderr) = (p.stdin, p.stdout) - - -Replacing popen2.* ------------------- -Note: If the cmd argument to popen2 functions is a string, the command -is executed through /bin/sh.
