Some of the below specified options can have their default values set in s3cmd config file (by default $HOME/.s3cmd). As it's a simple text file feel free to open it with your favorite text editor and do any changes you like.

show this help message and exit
Invoke interactive (re)configuration tool. Optionally use as '--configure s3://some-bucket' to test access to a specific bucket instead of attempting to list them all.
Config file name. Defaults to $HOME/.s3cfg
Dump current configuration after parsing config files and command line options and exit.

Use HTTPS connection when communicating with S3. (default)
Don't use HTTPS.
Encrypt files before uploading to S3.
Don't encrypt files.
Force overwrite and other dangerous operations.
Continue getting a partially downloaded file (only for [get] command).
Continue uploading partially uploaded files or multipart upload parts. Restarts parts/files that don't have matching size and md5. Skips files/parts that do. Note: md5sum checks are not always sufficient to check (part) file equality. Enable this at your own risk.

Filenames and paths matching GLOB will be included even if previously excluded by one of --(r)exclude(-from) patterns
Read --include GLOBs from FILE
Same as --include but uses REGEXP (regular expression) instead of GLOB
Read --rinclude REGEXPs from FILE
Read list of source-file names from FILE. Use - to read from stdin.
Region to create bucket in. As of now the regions are: us-east-1, us-west-1, us-west-2, eu-west-1, eu- central-1, ap-northeast-1, ap-southeast-1, ap- southeast-2, sa-east-1
HOSTNAME:PORT for S3 endpoint (default: s3.amazonaws.com, alternatives such as s3-eu- west-1.amazonaws.com). You should also set --host- bucket.

Don't guess MIME-type and use the default type instead.
Don't use mime magic when guessing MIME-type.
Force MIME-type. Override both --default-mime-type and --guess-mime-type.
Add a given HTTP header to the upload request. Can be used multiple times. For instance set 'Expires' or 'Cache-Control' headers (or both) using this option.

Add encoding to these comma delimited extensions i.e. (css,js,html) when uploading to S3 )
Use the S3 name as given on the command line. No pre- processing, encoding, etc. Use with caution!
Disable multipart upload on files bigger than --multipart-chunk-size-mb

One of the most powerful commands of s3cmd is s3cmd sync used for synchronising complete directory trees to or from remote S3 storage. To some extent s3cmd put and s3cmd get share a similar behaviour with sync.

Basic usage common in backup scenarios is as simple as:

	s3cmd sync /local/path/ s3://test-bucket/backup/

This command will find all files under /local/path directory and copy them to corresponding paths under s3://test-bucket/backup on the remote side. For example:

	/local/path/file1.ext         ->  s3://bucket/backup/file1.ext
	/local/path/dir123/file2.bin  ->  s3://bucket/backup/dir123/file2.bin

However if the local path doesn't end with a slash the last directory's name is used on the remote side as well. Compare these with the previous example:

	s3cmd sync /local/path s3://test-bucket/backup/
will sync: 
	/local/path/file1.ext         ->  s3://bucket/backup/path/file1.ext
	/local/path/dir123/file2.bin  ->  s3://bucket/backup/path/dir123/file2.bin

To retrieve the files back from S3 use inverted syntax:

	s3cmd sync s3://test-bucket/backup/ ~/restore/
that will download files: 
	s3://bucket/backup/file1.ext         ->  ~/restore/file1.ext
	s3://bucket/backup/dir123/file2.bin  ->  ~/restore/dir123/file2.bin

Without the trailing slash on source the behaviour is similar to what has been demonstrated with upload:

	s3cmd sync s3://test-bucket/backup ~/restore/
will download the files as: 
	s3://bucket/backup/file1.ext         ->  ~/restore/backup/file1.ext
	s3://bucket/backup/dir123/file2.bin  ->  ~/restore/backup/dir123/file2.bin

All source file names, the bold ones above, are matched against exclude rules and those that match are then re-checked against include rules to see whether they should be excluded or kept in the source list.

For the purpose of --exclude and --include matching only the bold file names above are used. For instance only path/file1.ext is tested against the patterns, not /local/path/file1.ext

Both --exclude and --include work with shell-style wildcards (a.k.a. GLOB). For a greater flexibility s3cmd provides Regular-expression versions of the two exclude options named --rexclude and --rinclude. The options with ...-from suffix (eg --rinclude-from) expect a filename as an argument. Each line of such a file is treated as one pattern.

There is only one set of patterns built from all --(r)exclude(-from) options and similarly for include variant. Any file excluded with eg --exclude can be put back with a pattern found in --rinclude-from list.

Run s3cmd with --dry-run to verify that your rules work as expected. Use together with --debug get detailed information about matching file names against exclude and include rules.

For example to exclude all files with ".jpg" extension except those beginning with a number use:

--exclude '*.jpg' --rinclude '[0-9].*.jpg'

To exclude all files except "*.jpg" extension, use:

--exclude '*' --include '*.jpg'

To exclude local directory 'somedir', be sure to use a trailing forward slash, as such:

--exclude 'somedir/'

For the most up to date list of options run: s3cmd --help
