at least, need to escape the *'s there.

at second either escape the ( and ) by backslash (pass the "\$" and "\$" to shell)

<pre><code>cmd = ["find", ".", "-type", "f", "\$", "-iname", "\\*foo\\*", "!", "-name", ".\\*", "\$"]
</code></pre>

or even just get rid of those ( and ) - 

<pre><code>cmd = ["find", ".", "-type", "f", "-iname", "\\*foo\\*", "!", "-name", ".\\*"]
</code></pre>

should work just fine

blocks|key|2520758|text|我也遇到了这个问题，我相信你现在已经弄明白了，但我想我会权衡一下，以防其他人遇到同样的问题。你会发现，这是由于Python在使用Popen时实际在做什么(当使用shell=True时，python基本上只是使用/bin/sh+-c来传入命令(Python's+subprocess.Popen()+results+differ+from+command+line?)。shell默认情况下为False，因此如果省略此参数或将其设置为False，则将使用'executable‘中指定的任何内容。文档在这里有更多的细节：https://docs.python.org/2/library/subprocess.html#subprocess.Popen|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2520759|按照这些思路应该是可行的。|2520760|import+subprocess

I ran into this issue as well, and I'm sure you've figured this out by now but I figured I'd weigh in just in case anyone else runs into the same issue. Come to find out, this happens due to what Python is actually doing when you use Popen (When shell=True is used, python is basically just using /bin/sh -c to pass in your command (<a href="https://stackoverflow.com/questions/9231074/pythons-subprocess-popen-results-differ-from-command-line">Python&#39;s subprocess.Popen() results differ from command line?</a>). shell is False by default, so if you omit this or set it to False, whatever is specified in 'executable' will be used. The docs go into more detail here: <a href="https://docs.python.org/2/library/subprocess.html#subprocess.Popen" rel="nofollow noreferrer">https://docs.python.org/2/library/subprocess.html#subprocess.Popen</a>

Something along these lines should work

<pre><code>import subprocess
cmd = 'find . -type f -iname "*foo*" ! -name ".*"'
sp = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
print sp.communicate()[0].split()
</code></pre>

blocks|key|2730448|text|在Python3.7中，subprocess.run()你可以把空格上的命令拆分成一个列表，字符串就可以了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2730449|除了subrocess.run()之外，文档中没有任何内容。|offset|length|2730450|我无法将命令扩展为列表来工作，而字符串却工作得很好。|2730451|cmd+=+"find+.+-type+f+-iname+\*foo\*+!+-name+.\\*"

In python 3.7 subprocess.run() you can drop splitting cmd on spaces into a list, string will do just fine. 

Nothing in the documentation though <a href="https://docs.python.org/3/library/subprocess.html#subprocess.run" rel="nofollow noreferrer">subrocess.run()</a>.

I was unable to get a command expanded into a list to work, while the string worked fine.

<pre><code>cmd = "find . -type f -iname \*foo\* ! -name .\\*"
print(cmd)
ret = subprocess.run(cmd, shell=True, capture_output=True)
print(ret)
</code></pre>

Testing:

<pre><code>$ find . -type f -iname \*foo\* ! -name .\*
./foobar.txt
./barfoo.txt

$ ./findfoo.py
find . -type f -iname \*foo\* ! -name .\*
CompletedProcess(args='find . -type f -iname \\*foo\\* ! -name .\\*',
 returncode=0, stdout=b'./foobar.txt\n./barfoo.txt\n', stderr=b'')
</code></pre>

I'd like to execute <code>find</code> with multiple conditions, for example: find foo excluding hidden files:

<pre><code>find . -type f $ -iname '*foo*' ! -name '.*' $
</code></pre>

Python code:

<pre><code>import subprocess

cmd = ["find", ".", "-type", "f", "(", "-iname", "*foo*", "!", "-name", ".*", ")"]
sp = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
print sp.communicate()[0].split()
</code></pre>

Can somebody explain what I'm missing? Thanks!

Python - execute find with multiple conditions using Popen

Python

我想在有多个条件的情况下执行find，例如:查找foo，排除隐藏文件：find . -type f $ -iname '*foo*' ! -name '.*' $Python代码：import subprocesscmd = ["find", ".", "-type", "f", "(", "-iname", "*...
