in reply to mkdir usage

mkdir "abc", "0777" or die "Can't mkdir abc: $!";

The second argument to mkdir expects a numerical value so providing a string means it will be interpreted as a number and the string "0777" is numerically different than the number 0777:

$ perl -le'print 0 + "0777"' 777 $ perl -le'print 0 + 0777' 511 $ perl -e'mkdir "testone", 0777 or die "Cannot mkdir testone because: +$!"' $ ls -dl testone drwxr-xr-x 2 john john 4096 2012-12-20 21:12 testone $ rmdir testone $ perl -e'mkdir "testone", "0777" or die "Cannot mkdir testone because +: $!"' $ ls -dl testone dr----x--t 2 john john 4096 2012-12-20 21:13 testone $ rmdir testone
