You would do well to read some of the literature on posting questions on help forums effectively. See, for example, I know what I mean. Why don't you?, How (Not) To Ask A Question, How do I post a question effectively? or How To Ask Questions The Smart Way.

When you directly interpolate your name into your string, it's like you literally typed that on the command line. If file names contain whitespace or shell meta characters, then the literally-interpolated string will mean something other than you intend. The solution is to use techniques other than direct interpolation -- there are a number of ways to get Perl to do the heavy lifting for you. I posted one such solution in Re: Using wildcards to open files.. What doesn't work about it? Have you even tried it?

I'm guessing that this is a Windows system since the solution posted would have worked otherwise. The Windows command line does not escape the same way that most systems do. In particular, it does not read "\ " as an in-name space. What you need to do for a MS system is wrap the name in double quotes, like $cmd = qq{perl < "$file"};

#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.
