Rails - Jun 2012 - Opening a file having white spaces on is name with the default program

Hello,

In my rails application, I have a file which name is: "d:/Copy of
t.txt".

I want to open it with the default program.

This file is a TXT file but it can be another kind of file (png, pdf,
etc) and can have, or not, white spaces on his path/name.

I''ve tried several ways to do it but, until now, I was not able to
accomplish by goal.

I have tried:

f1 = "d:/Copy of t.txt"

#system %{cmd /c "start #{f1}"}
#cmd = ''cmd /c "start '' + f1 + ''"''
#cmd = ''cmd /c """start '' + f1 +
''"""''
#cmd = "cmd /c ""start ''" + f1 +
"''"""
cmd = "cmd /c ""start ''" + f1 +
"''"""

system (cmd)

But no one of these solutions has worked.

Anyone can help me?

Thank you

Best regards

I don''t use windows, but you could try escaping the space "foo\
bar"

Hello,

Thanks for your answer. However, still not working...

f1 = "d:/Copy of t.txt"
f1 = f1.gsub(" ", "\\ ")

#system %{cmd /c "start #{f1}"}
#cmd = ''cmd /c "start '' + f1 + ''"''
#cmd = ''cmd /c """start '' + f1 +
''"""''
#cmd = "cmd /c ""start ''" + f1 +
"''"""
cmd = "cmd /c ""start ''" + f1 +
"''"""

system (cmd)

Have you tried inserting
puts cmd
then copying and pasting the output into the terminal to see if that works?

For a Microsoft DOS file name it is wrong.  It should be "d:\Copy of
t.txt".  Your problem could simply be the escaping of the backslash.  As
you have shown it in rails, you would be escaping the C character.

Hello,

Thanks for your answer.

I have made a put of the command

f1 = "d:/sat - Copy.png"
f1 = f1.gsub(" ", "\ ")
cmd = ''cmd /c "start '' + f1 + ''"''
puts "CMD: " + cmd
system (cmd)

....and the result is the following one:

cmd /c "start d:/sat - Copy.png"

In attachment, I''ve putted a picture with the error.

Thanks

Regards

Exactly what command are you trying to execute?
