bm ls
Syntax
The bm ls command lists buckets and objects on Buckit or another
S3-compatible service.
You can also use bm ls against the local filesystem to produce similar
results as the ls command.
The following command lists all objects and object versions in the
mydata bucket on the mybuckit Buckit deployment:
bm ls --recursive --versions mybuckit/mydata
The output resembles the following:
[2022-11-08 11:30:24 PST] 52MB STANDARD log-data.csv
[2022-11-09 12:20:18 PST] 120MB WARM videos/event-2022-11-09.mp4
STANDARDmarks objects stored on the Buckit deploymentWARMmarks objects stored on the remote tier with matching namevideos/indicates the prefix for the object
The command has the following syntax:
bm [GLOBALFLAGS] ls \
[--incomplete] \
[--recursive] \
[--rewind] \
[--versions] \
[--summarize] \
ALIAS [ALIAS ...]

[]indicate optional parameters.Parameters sharing a line are mutually dependent.
Parameters separated using the pipe
|operator are mutually exclusive.
Copy the example to a text editor and modify as-needed before running the command in the terminal/shell.
Parameters
- ALIAS
Required The object or objects to copy.
For listing objects on Buckit, specify the alias and the full path to that object (e.g. bucket and path to object). For example:
bm ls play/mybucket/object.txt
For listing objects on a local filesystem, specify the full path to that object. For example:
bm ls ~/mydata/object.txt
If you specify a directory or bucket to
ALIAS, you must also specify--recursiveto recursively list the contents of that directory or bucket. If you omit the--recursiveargument,lsonly lists objects in the top level of the specified directory or bucket.
- incomplete, -I
Optional Returns any incomplete uploads on the specified
ALIASbucket.
- --recursive, r
Optional Recursively lists the contents of each bucket or directory in the
ALIAS.
- --rewind
- Optional
Directs
bm lsto operate only on the object version(s) that existed at specified point-in-time.To rewind to a specific date in the past, specify the date as an ISO8601-formatted timestamp. For example:
--rewind "2020.03.24T10:00".To rewind a duration in time, specify the duration as a string in
#d#hh#mm#ssformat. For example:--rewind "1d2hh3mm4ss".
--rewindrequires that the specifiedALIASbe an S3-compatible service that supports Bucket Versioning. For Buckit deployments, usebm versionto enable or disable bucket versioning.Use
--rewindand--versionstogether to display on those object versions which existed at a specific point in time.
- --versions
- Optional
Directs
bm lsto operate on all object versions that exist in the bucket.--versionsrequires that the specifiedALIASbe an S3-compatible service that supports Bucket Versioning. For Buckit deployments, usebm versionto enable or disable bucket versioning.Use
--versionsand--rewindtogether to display on those object versions which existed at a specific point in time.
Global Flags
This command supports any of the global flags.
Examples
List Bucket Contents
Use bm ls to list the contents of a bucket:
bm ls [--recursive] ALIAS/PATH
Replace
PATHwith the path to the bucket on the S3-compatible host.If specifying the path to the S3 root (
ALIASonly), include the--recursiveoption.
List Object Versions
Use bm ls --versions to list all versions of an object:
bm ls --versions ALIAS/PATH
Replace
PATHwith the path to the bucket or object on the S3-compatible host.
Requires Versioning
bm ls requires bucket versioning to
use this feature. Use bm version to enable versioning on a bucket.
List Bucket Contents at Point in Time
Use bm ls --versions to list all versions of an object:
bm ls --rewind DURATION ALIAS/PATH
Replace
PATHwith the path to the bucket or object on the S3-compatible host.Replace
DURATIONwith the point-in-time in the past at which the command returns the object. For example, specify30dto return the version of the object 30 days prior to the current date.
Requires Versioning
bm ls requires bucket versioning to
use this feature. Use bm version to enable versioning on a bucket.
Behavior
S3 Compatibility
The bm commandline tool is built for compatibility with the AWS S3 API and is tested with Buckit and AWS S3 for expected functionality and behavior.
Buckit provides no guarantees for other S3-compatible services, as their S3 API implementation is unknown and therefore unsupported. While bm commands may work as documented, any such usage is at your own risk.
