in thread Construct command portable way

In IPC::Exe, I do the following:

# non-Unix: escape command so that it feels Unix-like
my @cmd = $non_unix
              ? map {
                    (my $x = $_)
                        =~ s/(\\"|")/$1 eq '"' ? '\\"' : '\\\\\\"'/ge;
                    qq("$x");
                } @_
              : @_;

before exec { $cmd[0] } @cmd; (See the quoting: test in t/02_IPC-Exe.t)

This helps to get around most of the quoting issues under Win32.

This thread about quoting issues reminds me why I use perl (mainly for direct command line use) instead of sed for I, well, rather not deal with quoting issues (on a Unix-like system in bourne like (z)shell). My impending doom awaits on the other side.	[reply]
