What problem are you trying to solve?

Creating new RabbitMQ user

[mkuratczyk]

This has nothing to do with RabbitMQ - it's about how a command line works: some characters have a special meaning and you need to escape them / put the strings in quotes to pass as a value.

Additionally, RabbitMQ 3.7 has been out of support for many years.

@adiganeshvema there is a dedicated section in the docs about generated passwords and shell escaping.

[michaelklishin]

Running RabbitMQ 3.7.x at this point is entirely irresponsible. Even 3.7.28 is 4.5 years old, and 3.7.0 has shipped in late 2017.

Time to upgrade.
