in thread how to dir a directory that have space

By way of example of the inconsistent nature of the internal handling of the list form:

Apparently perl isn't to blame, see exec always invokes the shell? win32

Win32::ShellQuote can be a cure

    I'm not sure how you draw that conclusion.

    1. system is not exec; nor vice versa.

      It is perfectly feasible and simple to invoke a command via system without going through the shell:

      [0] Perl> system q[perl -wE" say for @ARGV; <STDIN>" 1 2 "1 2" "1 \"2\
+" 3"];;
1
2
1 2
1 "2" 3

    2. That thread is very muddled.

      The conclusions drawn do not appear to match up with the code executed.

    As for Win32::ShellQuote; I've never found a need for it. I use the scalar form of system & open; quote as I would in the shell, and it just works. The problem with the list form is it does stuff to what you pass; but what it does is undocumented; thus you're always fighting 'intelligence' that isn't very.

      system is not exec

      Not sure what you mean by that? From system:

      system LIST ... Does exactly the same thing as exec LIST, except that a fork is done first and the parent process waits for the child process to exit.

        Windows doesn't have fork!
