OPTIONS
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.
-h, --help
show this help message and exit
--configure
Invoke interactive (re)configuration tool. Optionally use as '--configure s3://come-bucket' to test access to a specific bucket
instead of attempting to list them all.
-c FILE, --config=FILE
Config file name. Defaults to /home/mludvig/.s3cfg
--dump-config
Dump current configuration after parsing config files and command line options and exit.
-n, --dry-run
Only show what should be uploaded or downloaded but don't actually do it. May still perform S3 requests to get bucket listings and
other information though (only for file transfer commands)
-e, --encrypt
Encrypt files before uploading to S3.
--no-encrypt
Don't encrypt files.
-f, --force
Force overwrite and other dangerous operations.
--continue
Continue getting a partially downloaded file (only for [get] command).
--skip-existing
Skip over files that exist at the destination (only for [get] and [sync] commands).
-r, --recursive
Recursive upload, download or removal.
--check-md5
Check MD5 sums when comparing files for [sync]. (default)
--no-check-md5
Do not check MD5 sums when comparing files for [sync]. Only size will be compared. May significantly speed up transfer but may also

EXAMPLES
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/ /tmp/restore/
that will download files:
s3://bucket/backup/file1.ext -> /tmp/restore/file1.ext
s3://bucket/backup/dir123/file2.bin -> /tmp/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 /tmp/restore/
will download the files as:
s3://bucket/backup/file1.ext -> /tmp/restore/backup/file1.ext
s3://bucket/backup/dir123/file2.bin -> /tmp/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 file-
name 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'
