swift — OpenStack Swift client tool
swift [options] <command> [args]
The swift tool is a command line utility for communicating with an OpenStack Object Storage (Swift) environment. It allows one to perform several types of operations.
- stat [command-options] [container] [object]
Displays information for the account, container, or object depending on the args given (if any). In verbose mode, the Storage URL and the authentication token are displayed as well. Option --lh reports sizes in human readable format similar to ls -lh.
- list [command-options] [container]
Lists the containers for the account or the objects for a container. The -p <prefix> or --prefix <prefix> is an option that will only list items beginning with that prefix. The -d <delim> or --delimiter <delim> is option (for container listings only) that will roll up items with the given delimiter (see OpenStack Swift general documentation for what this means).
The -l or --long and --lh options provide more detail, similar to ls -l and ls -lh, the latter providing sizes in human readable format (eg 3K, 12M, etc). These latter 2 switches use more overhead to get those details, which is directly proportional to the number of container or objects being listed. With the -t or --total option they only report totals.
- upload [command-options] container file_or_directory [file_or_directory] [...]
Uploads to the given container the files and directories specified by the remaining args. The -c or --changed is an option that will only upload files that have changed since the last upload. The --object-name <object-name> is an option that will upload file and name object to <object-name> or upload dir and use <object-name> as object prefix. If the file name is "-", reads the content from standard input. In this case, --object-name is required and no other files may be given. The -S <size> or --segment-size <size> and --leave-segments and others are options as well (see swift upload --help for more).
- post [command-options] [container] [object]
Updates meta information for the account, container, or object depending on the args given. If the container is not found, it will be created automatically; but this is not true for accounts and objects. Containers also allow the -r (or --read-acl) and -w (or --write-acl) options. The -m or --meta option is allowed on all and used to define the user meta data items to set in the form Name:Value. This option can be repeated. For more details and options see swift post --help. Example: post -m Color:Blue -m Size:Large
- copy [command-options] container object
Copies an object to a new destination or adds user metadata to the object (current user metadata will be preserved, in contrast with the post command) depending on the args given. The --destination option sets the destination in the form /container/object. If not set, the object will be copied onto itself which is useful for adding metadata. The -M or --fresh-metadata option copies the object without the existing user metadata. The -m or --meta option is always allowed and is used to define the user metadata items to set in the form Name:Value (this option can be repeated). For more details and options see swift copy --help.
- download [command-options] [container] [object] [object] [...]
Downloads everything in the account (with --all), or everything in a container, or a list of objects depending on the args given. For a single object download, you may use the -o [--output] <filename> option to redirect the output to a specific file or if "-" then just redirect to stdout or with --no-download actually not to write anything to disk. The --ignore-checksum is an option that turns off checksum validation. You can specify optional headers with the repeatable cURL-like option -H [--header]. For more details and options see swift download --help. The --ignore-mtime option ignores the x-object-meta-mtime metadata entry on the object (if present) and instead creates the downloaded files with fresh atime and mtime values.
- delete [command-options] [container] [object] [object] [...]
Deletes everything in the account (with --all), or everything in a container, or all objects in a container that start with a given string (given by --prefix), or a list of objects depending on the args given. Segments of manifest objects will be deleted as well, unless you specify the --leave-segments option. For more details and options see swift delete --help.
- capabilities [command-options] [proxy-url]
Displays cluster capabilities. If the proxy-url option is not provided the storage-url retrieved after authentication is used as proxy-url.
By default, the output includes the list of the activated Swift middlewares as well as relevant options for each one. Additionally the command displays relevant options for the Swift core.
The --json option will print a json representation of the cluster capabilities. This is typically more suitable for consumption by other programs, such as jq.
Example: capabilities https://swift.example.com
- tempurl [command-option] method time path key
Generates a temporary URL allowing unauthenticated access to the Swift object at the given path, using the given HTTP method, for the given time, using the given TempURL key.
The time can be specified either as an integer denoting the amount of seconds the temporary URL is valid, or as an ISO 8601 timestamp in one of following formats: Complete date: YYYY-MM-DD (eg 1997-07-16), complete date plus hours, minutes and seconds: YYYY-MM-DDThh:mm:ss (eg 1997-07-16T19:20:30) or complete date plus hours, minutes and seconds with UTC designator: YYYY-MM-DDThh:mm:ssZ (eg 1997-07-16T19:20:30Z). Be aware that if you do not use the latter format, the timestamp is generated using your locale timezone. If the first format is used, the time part used will equal to 00:00:00.
With the --prefix-based option a prefix-based URL is generated.
The option --iso8601 provides ISO 8601 UTC timestamps instead of Unix timestamps inside the generated URL.
If optional --absolute argument is provided and the time argument is specified in seconds, the seconds are interpreted as a Unix timestamp at which the URL should expire.
Example: tempurl GET $(date -d "Jan 1 2016" +%s) /v1/AUTH_foo/bar_container/quux.md my_secret_tempurl_key --absolute
Display auth related authentication variables in shell friendly format. For examples see swift auth --help.
