Examples

The msgpack command accepts input as arguments:

$ msgpack -j '{"message": "Hello, world!"}'
gadtZXNzYWdlrUhlbGxvLCB3b3JsZCE=

$ msgpack -J -i=2 gadtZXNzYWdlrUhlbGxvLCB3b3JsZCE=
{
  "message": "Hello, world!"
}

Or, msgpack can read input from, and write output to, a file:

$ msgpack -J -i=2 gadtZXNzYWdlrUhlbGxvLCB3b3JsZCE= -o file.json

$ msgpack -j file.json
gadtZXNzYWdlrUhlbGxvLCB3b3JsZCE=

It also accepts input via stdin, supporting the use of pipes:

$ msgpack -j '{"message": "Hello, world!"}' | msgpack -J -i=2
{
  "message": "Hello, world!"
}
