I hardly ever use the local RDoc documentation of my installed Ruby gems. Typing in –no-rdoc –no-ri every time I install a gem is cumbersome. The gem takes longer to install and it uses up unnecessary disk space. That annoyance goes doubly when installing gems on a server.

Luckily, RubyGems allows to set default options in a file called .gemrc which should be placed in your home directory. The syntax is in YAML format, therefore straightforward for a Ruby programmer. Just add this line to .gemrc and you are golden.

    gem: --no-rdoc --no-ri
  

A list of all options can be found here.

Just in case you want to flush the DNS cache on an OSX system for whatever reason, this command gets the job done:

    dscacheutil -flushcache
