How do I run a bash script inside Python, but act as if it's running from another directory?
提问by TIMEX
subprocess.call(["/home/blah/trunk/blah/run.sh", "/tmp/ad_xml", "/tmp/video_xml"])
I do this. However, inside my run.sh, I have "relative" paths. So, I have to "cd" into that directory, and then run the shell script. How do I do that?
我这样做。但是，在我的 run.sh 中，我有“相对”路径。所以，我必须“cd”到那个目录，然后运行shell脚本。我怎么做？

Use the cwdargument to subprocess.call()
使用cwd参数subprocess.call()
From the docs here: http://docs.python.org/library/subprocess.html
从这里的文档：http: //docs.python.org/library/subprocess.html
If
cwdis not None, the child's current directory will be changed tocwdbefore it is executed. Note that this directory is not considered when searching the executable, so you can't specify the program's path relative tocwd.
如果
cwd不是 None，cwd则在执行之前将更改子级的当前目录 。请注意，搜索可执行文件时不考虑此目录，因此您不能指定程序相对于cwd.
Example:
例子：
subprocess.call(["/home/blah/trunk/blah/run.sh", "/tmp/ad_xml", "/tmp/video_xml"], cwd='/tmp')

Well, you could use subprocess.Popenwith Shell = True and cwd = "Your desired working directory"
好吧，你可以使用subprocess.Popen和 Shell = True 和 cwd = "你想要的工作目录"
EDIT:It appears that call has the same arguments so just setting a cwd argument would work:
编辑：似乎调用具有相同的参数，因此只需设置 cwd 参数即可：
subprocess.call(["/home/blah/trunk/blah/run.sh", "/tmp/ad_xml", "/tmp/video_xml"], cwd="PATH")

You can supply your working directory like this:
您可以像这样提供您的工作目录：
subprocess.call(["/home/blah/trunk/blah/run.sh", "/tmp/ad_xml", "/tmp/video_xml"], cwd="/home/blah/trunk/blah")
subprocess.call(["/home/blah/trunk/blah/run.sh", "/tmp/ad_xml", "/tmp/video_xml"], cwd="/home/blah/trunk/blah")
