## i am newbie of ruby , but i met a strange problem when use

## #echo hello |ruby -ve ‘puts ARGF.readlines’ ruby 1.8.3 (2005-09-21) [i686-linux] hello

it’s ok

## but when i append a argument with pipe

# echo hello |ruby -ve ‘puts ARGF.readlines’ somearg

## ruby 1.8.3 (2005-09-21) [i686-linux] -e:1:in `readlines’: No such file or directory - somearg (Errno::ENOENT) from -e:1

why ruby say ‘no such file or diectory’? can anyboby explain it?

thanks

ARGF doesn’t equal STDIN.

Quotation from the document:

- The global constant ARGF (also accessible as $\<) provides an
- IO-like stream which allows access to all files mentioned on the
- command line (or STDIN if no files are mentioned).
