Question

我一直试图解决这个问题好几天了，并希望得到一些帮助 -

基本上，我编写了以下Python脚本

import os, sys

# =__=__=__=__=__=__=__ START MAIN =__=__=__=__=__=__=__
if __name__ == '__main__':

# initialize variables
all_files = []

# directory to download data siphon files to
dDir = '/path/to/download/directory/'

# my S3 bucket
s3bucket = "com.mybucket/"

foldername = "test"

# get a list of available feeds
feeds = <huge JSON object with URLs to feeds>

for item in range(feeds['count']):
    # ...check if the directory exists, and if not, create the directory...
    if not os.path.exists(folderName):
        os.makedirs(folderName)

    ... ... ...

    # Loop through all the splits
    for s in dsSplits:
        ... ... ...
        location = requestFeedLocation(name, timestamp)

        ... ... ...
        downloadFeed(location[0], folderName, nameNotGZ)

    # THIS IS WHERE I AM HAVING PROBLEMS!!!!!!!!!!!
    cmd = 's3cmd sync 'dDir+folderName+'/ s3://'+s3bucket+'/'
    os.system(cmd)

我的代码中的所有东西都可以工作......当我从命令行直接运行时，一切都按预期运行...但是，当我通过cron执行它时 - 以下不执行（其他所有操作）< / p>

# THIS IS WHERE I AM HAVING PROBLEMS!!!!!!!!!!!
cmd = 's3cmd sync 'dDir+folderName+'/ s3://'+s3bucket+'/'
os.system(cmd)

要回答几个问题，我以root身份运行cron，为root用户配置s3cmd，OS为Ubuntu 12.04，python版本为2.7，所有必需目录都具有读/写权限......

我错过了什么？

首先检查变量＆＃39; foldername＆＃39;在命令中你已经在变量中使用了N.
在命令语法中，您需要在+ dDir + folderName +

所以我希望命令如下所示..

cmd =＆＃39; s3cmd sync＆＃39; + dDir + foldername +＆＃39; / s3：//＆＃39; + s3bucket +＆＃39; /＆＃39;

使用os.system（CMD）

通过python脚本＆amp;运行s3cmd同步cron的
