undefined local variable or method '_FILE_'

[Diogo Veras]

Hi all,

Don't know why but when I try to use the _FILE_ variable I'm getting the
following error:

irb(main):001:0> puts File.dirname(_FILE_)
NameError: undefined local variable or method `_FILE_' for main:Object
from (irb):1
from :0

I've got this error in Windows Seven and Ubuntu 10.04 LTS, both using
Ruby 1.8.7

Have also tried running the code in .rb file but get the same error.
Neither File.dirname(_FILE_) nor only _FILE_ seems to work.

Looked about it everywhere but got nothing. Any idea..?

Regards,

You need to use __FILE__ (note the 2 underscores on each side).

It worked. Can't believe, you are right, have no idea how I let this
pass.

Thank you a lot.
