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
