to be honest s3cmd wasn't designed to be used this way. I have later
changed my mind and some new features are actually importable into other
python scripts (CloudFront module for example) but the core of s3cmd may
require some amount of work to be used that way. So it's not reasonably
possible to import stuff directly from s3cmd.
However you can import all the low-level functions from S3.* modules and
more or less copy and paste whatever you need from s3cmd to your
program. In most cases the s3cmd functions only do argument parsing and
output formatting and may not be directly usable from within your
application anyway.
Here's a quick re-implementation of 's3cmd ls' in a standalone script.
It only needs the S3.* modules but not the main script s3cmd:
$ cat s3-ls.py
#!/usr/bin/env python
import os
from S3.Exceptions import *
from S3.S3 import S3
from S3.Config import Config
from S3.Utils import formatDateTime
def buckets_list_all(s3):
response = s3.list_all_buckets()
for bucket in response["list"]:
print(u"%s s3://%s" % (
formatDateTime(bucket["CreationDate"]),
bucket["Name"],
))
if __name__ == "__main__":
config_file = os.path.join(os.getenv("HOME"), ".s3cfg")
cfg = Config(config_file)
s3 = S3(cfg)
buckets_list_all(s3)
This way you can probably integrate cmd_object_put to your application.
Or simply call s3cmd from os.system():
import os
ret = os.system("/usr/bin/s3cmd ls")
There's no need for a bash wrapper.
HTH,
Michal
