-SYNOPSIS
- s3put [-a/--access_key <access_key>] [-s/--secret_key <secret_key>]
- -b/--bucket <bucket_name> [-c/--callback <num_cb>]
- [-d/--debug <debug_level>] [-i/--ignore <ignore_dirs>]
- [-n/--no_op] [-p/--prefix <prefix>] [-k/--key_prefix <key_prefix>]
- [-q/--quiet] [-g/--grant grant] [-w/--no_overwrite] [-r/--reduced] path
-
- Where
- access_key - Your AWS Access Key ID. If not supplied, boto will
- use the value of the environment variable
- AWS_ACCESS_KEY_ID
- secret_key - Your AWS Secret Access Key. If not supplied, boto
- will use the value of the environment variable
- AWS_SECRET_ACCESS_KEY
- bucket_name - The name of the S3 bucket the file(s) should be
- copied to.
- path - A path to a directory or file that represents the items
- to be uploaded. If the path points to an individual file,
- that file will be uploaded to the specified bucket. If the
- path points to a directory, s3_it will recursively traverse
- the directory and upload all files to the specified bucket.
- debug_level - 0 means no debug output (default), 1 means normal
- debug output from boto, and 2 means boto debug output
- plus request/response output from httplib
- ignore_dirs - a comma-separated list of directory names that will
- be ignored and not uploaded to S3.
- num_cb - The number of progress callbacks to display. The default
- is zero which means no callbacks. If you supplied a value
- of "-c 10" for example, the progress callback would be
- called 10 times for each file transferred.
- prefix - A file path prefix that will be stripped from the full
- path of the file when determining the key name in S3.
- For example, if the full path of a file is:
- /home/foo/bar/fie.baz
- and the prefix is specified as "-p /home/foo/" the
- resulting key name in S3 will be:
- /bar/fie.baz
- The prefix must end in a trailing separator and if it
- does not then one will be added.
- key_prefix - A prefix to be added to the S3 key name, after any
- stripping of the file path is done based on the
- "-p/--prefix" option.
- reduced - Use Reduced Redundancy storage
- grant - A canned ACL policy that will be granted on each file
- transferred to S3. The value of provided must be one
- of the "canned" ACL policies supported by S3:
- private|public-read|public-read-write|authenticated-read
- no_overwrite - No files will be overwritten on S3, if the file/key
- exists on s3 it will be kept. This is useful for
- resuming interrupted transfers. Note this is not a
- sync, even if the file has been updated locally if
- the key exists on s3 the file on s3 will not be
- updated.
-
- If the -n option is provided, no files will be transferred to S3 but
- informational messages will be printed about what would happen.
