通过使用Python排除隐藏文件,在两个目录上执行diff

我正在尝试编写一个Python脚本来执行 diff -r 在两个目录上。我想排除目录中的隐藏文件。

这是我的。

source = "/Users/abc/1/"
target = "/Users/abc/2/"
bashCommand = 'diff -x ".*" -r ' + source + ' ' + target
# Below does not work either
# bashCommand = "diff -x '.*' -r " + source + ' ' + target

import subprocess

process = subprocess.Popen(bashCommand.split(), stdout=subprocess.PIPE)
output, error = process.communicate()
if output:
    print "Directories do not match: " + output
else:
    print "Directories match"

我知道我应该使用 -x '.*' 忽略点文件。我看着 this 所以发布。但这没有帮助。我该怎么写这行?

bashCommand = 'diff -x ".*" -r ' + source + ' ' + target

编辑1: 我也试过了,但也没用

pat = "-x \".*\""
bashCommand = "diff " + pat + " -r " + source + " " + target
print bashCommand

当我打印输出并手动运行命令时,它会按预期工作。但是,Python脚本并没有产生所需的结果

$python BashCommand.py
diff -x ".*" -r /Users/abc/1/ /Users/abc/2/
Directories do not match: Only in /Users/abc/1/: .a


$diff -x ".*" -r /Users/abc/1/ /Users/abc/2/
$
