in reply to Shorten windows paths too long

`H:; cd $olddirname; cd ..; move /Y $olddirname $newname` or die "Can' +t move $olddirname $newname: $!";

That is pretty broken code. `` (qx<>) doesn't return a boolean. It returns the output of the commands. So you are dieing if that command produces no output. And $! usually is irrelevant after qx() fails.

my $output= qx(H:; cd $olddirname; cd ..; move /Y $olddirname $newname +); if( 0 != $? ) { die "Can't move $olddirname $newname: $output"; }

Might be closer to correct.

    I stand corrected *blushing* I admit my code is remedial at best. I wasn't sure how to do that and gave my best guess. Thank you for the correction there. I'll fix my version per your recommendations.

    Thanks again,
