Title: RE: Cygwin Perl system() Invokes exec() Directly?





Hello again,


        That was quick...


>What is your perl summary (perl-V)?


        Please see attached...


>What is pwd?


        Hey, you've at least got to give me credit for not falling into that trap... :-)


                /usr/bin/perl -e '$x=system("wc",".bashrc");$y=system("wc < .bashrc");print"$x $y $!\n";'
        produces
                5       14      93      .bashrc
                0 -1 No such file or directory


        Thanks again...


                                        - Matt
