Remove dashes in UUID

Remove the dashes from a UUID using bash search and replace.


There is 1 alternative - vote for the best!

Terminal - Alternatives
python -c "from uuid import UUID; print UUID('63b726a0-4c59-45e4-af65-bced5d268456').hex;"

Remove dashes, also validates if it's a valid UUID (in contrast to simple string-replacement)

Know a better way?

If you can do better, submit your command here.

What others think

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

Thanks, I'm aware :-)

The site copied the original mistake when I submitted my command.

Comment by flatcap 329 weeks and 6 days ago

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?

Comment by unixmonkey365 327 weeks and 4 days ago

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}
