- --dump-config
- Dump current configuration after parsing config files and command line options and exit.

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.binHowever 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.binTo 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.binWithout 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.binAll 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'
