umoci [--help|-h] [--version|-v] [--log={debug|info|warn|error|fatal}] [--verbose] command [args]

umoci is a tool that allows for high-level modification of an OCI image layout and its tagged images. While umoci attempts to abstract the OCI image specification specifics, it is recommended that users of this tool read through the specification ⟨https://github.com/opencontainers/image-spec⟩ to make sure they understand the rough idea.

umoci is unique in that it is, at the time of writing, the first tool to allow for arbitrary modification of an OCI image in a high-level fashion (where all of the different blobs in an OCI image are all managed by umoci when doing a high-level operation such as umoci-repack(1)).

--help,  -h

Print usage statement.

--version,  -v

Print the version.

--cpu-profile=filename

Generate a CPU profile during umoci's execution and save it to filename.
 This file is stored in Go's pprof ⟨https://golang.org/pkg/runtime/pprof/⟩ format and can be analysed using go
 tool pprof or similar tools.

--log={debug|info|warn|error|fatal}

Set the logging level. The default is "warn".

--verbose

Alias for --log=info.
