Shorthand to clean up installed Rubygems (but don’t cleanup Rails)
I trimmed my installed Rubygems on my local development machine. The command “sudo gem cleanup” is just for that.
Only problem: What about my older Rails apps that require a specific version of Rails, ActiveRecord, etc.?
My solution:
gem list --no-versions | grep -v "^active" | grep -v "^action" | grep -v "^rails$" | xargs sudo gem cleanup {}
Any suggestions on how to make it even simpler?
