s5cmd v1.0.0 Release Notes

Release Date: 2020-04-01 // about 4 years ago

  • 🚀 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)
    • 0️⃣ 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.
