Variables

[Carl Yeksigian]

How do you: get the OS variable that you are currently running on
- AND -
the name of the user that is running the application?

How do you: get the OS variable that you are currently running on

What do you mean by "the OS variable"?

the name of the user that is running the application?

$ ruby -e 'p ENV["USER"]'
"nobu"
$ ruby -e 'p ENV["LOGNAME"]'
"nobu"
$ ruby -retc -e 'p Etc.getlogin'
"nobu"

How do you: get the OS variable that you are currently running on

Do you mean:
$ ruby -e "p RUBY_PLATFORM"
"i386-freebsd4.8"

(this is the platform the ruby interpreter was compiled under, which may or
may not be the same thing)
