Changelog

not released yet

Breaking changes

  • Adjacent slashes in key are no longer removed when uploading to remote. Before s5cmd cp file.txt s3://bucket/a//b///c/ would copy to s3://bucket/a/b/c/file.txt but now to s3://bucket/a//b///c/file.txt.(#459)
  • --endpoint-url will not accept URLs without scheme such as example.com. Instead, it will give an error and ask for an url with a scheme; either http://example.com or https://example.com (#496).

Features

  • Added --content-type and --content-encoding flags to cp command. (#264)
  • Added --profile flag to allow users to specify a named profile. (#353)
  • Added --credentials-file flag to allow users to specify path for the AWS credentials file instead of using the default location.
  • Added bench.py script under new benchmark folder to compare performances of two different builds of s5cmd. (#471)
  • Added --all-versions flag to ls, rm, du and select subcommands to apply operation on(/over) all versions of the objects. (#475)
  • Added --version-id flag to cat, cp/mv, rm, du and select subcommands to apply operation on(/over) a specific versions of the object. (#475)
  • Added bucket-version command to configure bucket versioning. Bucket name alone returns the bucket versioning status of the bucket. Bucket versioning can be configured with set flag. (#475)
  • Added --raw flag to cat and select subcommands. It disables the wildcard operations. (#475)

Improvements

  • Disable AWS SDK logger if log level is not trace. (##460)

  • Allow adjacent slashes to be used as keys when uploading to remote. (#459)

  • Debian packages are provided on releases page (#380)

  • Upgraded minimum required Go version to 1.17.

  • The sync command uses external sort instead of internal sort. This change reduces RAM usage from ~10 GB to ~1.5 GB for sync operation of a directory containing 1,000,000 files at a cost of speed (20% slower for 1,000,000 objects). For smaller directories (~50,000 files) there is no significant change in speed. (#483)

  • Improve auto-completion support of s5cmd for zsh and bash, start supporting pwsh and stop the support for fish. Now s5cmd can complete bucket names, s3 keys in a bucket and the local files. However, install-completion flag no longer installs the completion script to *rc files instead it merely gives instructions to install autocompletion and provides the autocompletion script (#500).

Bugfixes

  • Fixed a bug where (--stat) prints unnecessarily when used with help and version commands (#452)
  • Changed cp error message to be more precise. "given object not found" error message now will also include absolute path of the file. (#463)
  • Fixed a bug where some part of the destination path is removed by cp and sync subcommands (#360)
  • Fixed a bug where proxy is not being used when --no-verify-ssl flag is used. (#445)
  • Fixed unknown url format error when object key also includes s3:// e.g. s5cmd ls s3://foo/bar/s3://baz (#449)
  • Fixed a bug where the local file created for the download operation was not deleted if the download fails in Windows. (#348)

v2.0.0 - 4 Jul 2022

Breaking changes

  • Dropped inline comment feature for run command. Previously s5cmd supported a command with an inline comment like ls s3://bucket/object.gz # inline comment. (#309)
  • Changed homebrew installation command on macOS. Users can install s5cmd via brew install peak/tap/s5cmd. (#356)
  • Print usage errors to stderr instead of stdout and do not show help text on usage error. (#399)
  • Working directory of the Docker image changed to /aws from /. (#412)

Features

  • Added sync command to synchronize two given buckets, prefixes, or objects. (#3)
  • Added AWS Single Sign-On (SSO) profiles support. (#385)
  • Added --force-glacier-transfer flag to select command. (#346)
  • Added --ignore-glacier-warnings flag to cp, mv and select commands. (#346)
  • Added --request-payer flag to include x-amz-request-payer in header while sending GET, POST and HEAD requests. (#297) @Kirill888
  • Added --use-list-objects-v1 flag to force using S3 ListObjects API instead of ListObjectsV2 API. (#405) @greenpau
  • Added trace log level(--log=trace) which enables SDK debug logs.(#363)

Improvements

  • Upgraded minimum required Go version to 1.16.

Bugfixes

  • Fixed a bug about precedence of region detection, which auto region detection would always override region defined in environment or profile. (#325)
  • Fixed a bug where errors did not result a non-zero exit code. (#304)
  • Print error if the commands file of run command is not accessible. (#410)
  • Updated region detection call to use current session's address resolving method (#314)
  • Fixed a bug where lines with large tokens fail in run command. sync was failing when it finds multiple files to remove. (#435, #436)
  • Print usage error if given log level(--log) is not valid. (#430)
  • Fixed a bug where (--stat) is ignored when log level is error. (#359)

v1.4.0 - 21 Sep 2021

Features

  • Added select command. It allows to select JSON records from objects using SQL expressions. (#299) @skeggse
  • Added rb command to remove buckets. (#303)
  • Added --exclude flag to cp, rm, ls, du and select commands. This flag allows users to exclude objects with given pattern. (#266)
  • Added --raw flag to cp and rm commands. It disables the wildcard operations. It is useful when an object contains glob characters which interfers with glob expansion logic. (#235)
  • Added --cache-control and --expires flags to cp and mv commands. It adds support for setting cache control and expires header to S3 objects. (#318) @tombokombo
  • Added --force-glacier-transfer flag to cp command. It forces a transfer request on all Glacier objects. (#206)
  • Added --source-region and destination-region flags to cp command. It allows overriding bucket region. (#262) @kemege

Improvements

  • Added MacPorts installation option. (#311) @manojkarthick

  • Fixed data race for concurrent writes for expand (#330)
  • Fixed concurrent writes to the flags list of run command (#335)
  • Fixed options usage on mv command (#338)

v1.3.0 - 1 Jul 2021

Features

  • Added global --no-sign-request flag. API requests won't be signed and credentials won't be used if this option is provided. It is useful for accessing public buckets. (#285)

Improvements

  • If retryable errors are received during command execution, users now can see what's happening under the hood. (#261)
  • Update documentation about the AWS_PROFILE environment variable. (#275) @davebiffuk

Bugfixes

  • Fixed a bug where write-bit was required to upload a file. (#258)
  • Fixed a bug where object could not be found if S3 key contains certain special characters. (#279) @khacminh
  • s5cmd exits with code 1 if given command is not found. It was 0 before. (#295)

v1.2.1 - 3 Dec 2020

Improvements

  • Statically link s5cmd in Docker image (#250)

Bugfixes

  • Fixed a bug where HeadBucket request fails during region information retrieval. (#251, #252)

v1.2.0 - 5 Nov 2020

With this release, s5cmd automatically determines region information of destination buckets.

Features

  • Added global --dry-run option. It displays which command(s) will be executed without actually having a side effect. (#90)
  • Added --stat option for s5cmd and it displays program execution statistics before the end of the program output. (#148)
  • Added cross-region transfer support. Bucket regions are inferred, thus, supporting cross-region transfers and multiple regions in batch mode. (#155)

Bugfixes

  • Fixed incorrect MIME type inference for cp, give priority to file extension for type inference. (#214)
  • Fixed error reporting issue, where some errors from the ls operation were not printed.

Improvements

  • AWS S3 RequestTimeTooSkewed request error was not retryable before, it is now. (205)
  • For some operations errors were printed at the end of the program execution. Now, errors are displayed immediately after being detected. (#136)
  • From now on, docker images will be published on Docker Hub. (#238)
  • Changed misleading 'mirroring' examples in the help text of cp. (#213)

v1.1.0 - 22 Jul 2020

Breaking changes

  • Dropped storage class short codes display from default behaviour of ls operation. Instead, use -s flag with ls to see full names of the storage classes when listing objects.

Features

  • Added Server-side Encryption (SSE) support for mv/cp operations. It uses customer master keys (CMKs) managed by AWS Key Management Service. (#18)
  • Added an option to show full form of storage class when listing objects. (#165)
  • Add access control lists (ACLs) support to enable managing access to buckets and objects. (#26)

Bugfixes

  • Fixed infinite repetition issue on mv/cp operations which would occur if the destination matched the source wildcard. (#168)
  • Fixed windows filepath issue, where backslashes should be treated as the path delimiter. (#178)
  • All tests pass on windows, by converting and treating file paths to UNIX filepath format.
  • Fixed a transfer issue where the object path contains particular regex metacharacters. (#111) @brendan-matroid
  • Correctly parse object paths that contain whitespaces in run-mode. (#111) @brendan-matroid

Improvements

v1.0.0 - 1 Apr 2020

This is a major release with many breaking changes.

Breaking changes

  • Dropped get command. Users could get the same effect with s5cmd cp <src> ..
  • Dropped nested command support.
  • Dropped ! command. It was used to execute shell commands and was used in conjunction with nested commands.
  • s5cmd -f and s5cmd -f - usage has changed to s5cmd run. run command accepts a file. If not provided, it'll listen for commands from stdin.
  • Exit code for errors was 127. It is 1 now.
  • Dropped exit command. It was used to change the shell exit code and usually a part of the nested command usage.
  • Dropped local->local copy and move support. (#118)
  • All error messages are sent to stderr now.
  • -version flag is changed to version command.
  • Dropped batch-rm command. It was not listed in the help output. Now that we support variadic arguments, users can remove multiple objects by providing wildcards or multiple arguments to s5cmd rm command. (#106)
  • Virtual host style bucket name resolving is enabled by default for S3 and GCS. If you provide a custom endpoint via --endpoint-url flag (other than GCS and S3 transfer acceleration), s5cmd will fall back to the path-style. (#92)
  • Listing a non-existent object will return exit code 1, instead of 0. (#23)
  • -ds, -dw, -us and -uw global flags are no longer available. Multipart concurrency and part size flags are now part of the cp/mv command. New replacement flags are --concurrency | -c and --part-size | -p. (#110)
  • s5cmd cp command follows symbolic links by default (only when uploading to s3 from local filesystem). Use --no-follow-symlinks flag to disable this feature. (#17)
  • Dropped -parents flag from copy command. Copy behaviour has changed to preserve the directory hierarchy as a default. Optional -flatten flag is added to flatten directory structure. (#107)
  • Dropped -vv verbosity flag. --log flag is introduced.

Features

Bugfixes

  • Correctly set Content-Type of a file on upload operations. (#33)

  • AWS Go SDK is updated to support IAM role for service accounts. (#32)
  • For copy/move operations, s5cmd now creates destination directory if missing.
