如果用普通的gem list指令，列表的格式会是这样的：
....
Wiki2Go (1.17.1)
Wiki2Go is a Ruby Wiki
win32-service (0.5.2)
An interface for MS Windows services
wirble (0.1.2)
Handful of common Irb features, made easy.
ZenTest (3.4.3)
ZenTest provides 4 different tools and 1 library: zentest,
unit_diff, autotest, multiruby, and Test::Rails.
但有时我们不想要gem的说明文字，只需要gem的名字和版本。
我们可以用：
gem list|grep '^[a-zA-Z]'
达到目的。
