Forum: Ruby Open file that its name given by STDIN.gets

Hi all. I'm following the Zed Shaw's ruby tutorials.
in ex15 i've changed this line

filename = ARGV.first

to

filename = STDIN.gets

and this is the command line error:

→ ruby test.rb
test.rb
> test.rb:9:in `initialize': No such file or directory - aref (Errno::ENOENT)
  from test.rb:9:in `open'
  from test.rb:9:in `<main>'

what is the problem?
P.S. the ruby file is attached.

STDIN.read     ?

The read method reads data from the standard input, until it reaches the
end of the file. The EOF is produced by pressing Ctrl + D on Unix or 
Ctrl +
Z on Windows.

gets returns a string with a trailing newline. This means that, if you 
enter

test

as your file name, the variable filename will contain the string 
"test\n". You
can use String#chomp to remove it:

filename = STDIN.gets.chomp

I hope this helps

ِYou are right:)
that was the problem...
Thank you a lot Stefano :)

Please include short code snippets directly in the E-Mail
instead of using attachments!

The string returned from gets is always terminated by a newline
character that you need to remove:

filename = gets.chomp
