Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

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 :-)

[post edited]

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

Comment by flatcap 140 weeks and 2 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 138 weeks 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}
