What Others Think

I'D say 's/slash/dash/g' ( '-' is dash. '/' is a slash)

Thanks, I'm aware :-) [post edited] The site copied the original mistake when I submitted my command.

The Python variant is more safe since it also validates the UUID (throwing errors if its not a valid UUID)

upvoted. I never knew bash could do that without a pipe through sed. This is documented where?

The bash manual page ;-) man bash Look for section called "Parameter Expansion". The above example is doing a simple search and replace *inside* a shell variable. ${parameter/pattern/string}
