问题 Whenever I use a command in a subprocess with "|" in it doesn't work it has an output of Command "|" is unknown, try "in link help". Or when I put this: #!/usr/bin/python from subprocess import call from shlex import split interface = call(split("ip -o link show | awk '{print $2}' | grep wl")) It is giving the output of: Error: either "dev" is duplicate, or "awk" is a garbage. 回答1: You can use subprocess.check_output method and Popen class though I wasn't able to chain both pipe operations.

问题 I am executing bash command using python's subprocess.call(). I am taking user input as an argument to my command like below. my_command = 'command -option1 {0} -option2 {1}'.format(arg1, arg2) Here arg1 and arg2 are user inputs but the problem is user input can have quotes and spaces so I want to surround arguments by double quotes like this. my_command = 'command -option1 "{0}" -option2 "{1}"'.format(arg1, arg2) Since I have no control over user input, input can contains double quotes or

问题 Language: Python v2.6.2 OS: AIX 5.3 I'm using Python to restore some files from a backup to a test system - all commands are called in the manner below, however some just plain don't want to work. #!/usr/bin/python import subprocess, shlex cmd = 'sudo rm -rf /work/TEST/*' arg = shlex.split(cmd) # This does not work p = subprocess.Popen(arg) # This, however, works just fine p = subprocess.Popen(cmd, shell=True) If I remove the *'s from the commands they work fine (well, they work as they

What's the reverse of shlex.split?

问题 How can I reverse the results of a shlex.split? That is, how can I obtain a quoted string that would "resemble that of a Unix shell", given a list of strings I wish quoted? Update0 I've located a Python bug, and made corresponding feature requests here. 回答1: We now (3.3) have a shlex.quote function. It’s none other that pipes.quote moved and documented (code using pipes.quote will still work). See http://bugs.python.org/issue9723 for the whole discussion. subprocess.list2cmdline is a private

Python split string by spaces except when in quotes, but keep the quotes

问题 Am wanting to split the following string: Quantity [*,'EXTRA 05',*] With the desired results being: ["Quantity", "[*,'EXTRA 05',*]"] The closest I have found is using shlex.split, however this removes the internal quotes giving the following result: ['Quantity', '[*,EXTRA 05,*]'] Any suggestions would be greatly appreciated. EDIT: Will also require multiple splits such as: "Quantity [*,'EXTRA 05',*] [*,'EXTRA 09',*]" To: ["Quantity", "[*,'EXTRA 05',*]", "[*,'EXTRA 09',*]"] 回答1: To treat

问题 How, in Python, can I use shlex.split() or similar to split strings, preserving only double quotes? For example, if the input is "hello, world" is what 'i say' then the output would be ["hello, world", "is", "what", "'i", "say'"] . 回答1: import shlex def newSplit(value): lex = shlex.shlex(value) lex.quotes = '"' lex.whitespace_split = True lex.commenters = '' return list(lex) print newSplit('''This string has "some double quotes" and 'some single quotes'.''') 回答2: You can use shlex.quotes to

You can use shlex.quotes to control which characters will be considered string quotes. You'll need to modify shlex.wordchars as well, to keep

python, windows : parsing command lines with shlex

由 隐身守侯 提交于 2019-11-30 21:23:17
When you have to split a command-line, for example to call Popen , the best practice seems to be subprocess.Popen(shlex.split(cmd), ... but RTFM The shlex class makes it easy to write lexical analyzers for simple syntaxes resembling that of the Unix shell ... So, what's the correct way on win32? And what about quote parsing and POSIX vs non-POSIX mode? There is no valid command-line splitting function so far in the Python stdlib for Windows/multi-platform so far. (Mar 2016) subprocess So in short for subprocess.Popen .call etc. best do like: if sys.platform == 'win32': args = cmd else: args =
