Environmental variables in Ruby 1.8.5

Chris Gehlker

I get:
irb(main):001:0> ENV.keys.size
=> 15
irb(main):002:0> ENV.keys[0..14]
=> ["TERM_PROGRAM", "TERM", "SHELL", "CLICOLOR",
"TERM_PROGRAM_VERSION", "USER", "__CF_USER_TEXT_ENCODING", "PATH",
"RI", "PWD", "SHLVL", "HOME", "LOGNAME", "SECURITYSESSIONID", "_"]

Which is a smaller set of environmental variables quite different
than what is described in the Pickaxe Book. Did the Ruby powers trim
them? Just curious.

$ env | wc -l
23
$ ruby -e 'puts ENV.size'
23

Thanks Kent,
