in reply to problem in mkdir

The problem is that you are trying to create a directory in a directory that does not exists yet. Take a look at this:
$ cat #!/usr/bin/perl -w my $d1 = "d1"; my $d2 = "d2"; mkdir "/tmp/$d1/$d2" or warn __LINE__ . " mkdir /tmp/$d1/$d2 failed:$! +\n"; mkdir "/tmp/$d1" or warn __LINE__ . " mkdir /tmp/$d1 failed:$!\n"; mkdir "/tmp/$d1/$d2" or warn __LINE__ . " mkdir /tmp/$d1/$d2 failed:$! +\n"; $ ./ 6 mkdir /tmp/d1/d2 failed:No such file or directory
So my first mkdir command fails to make direcotry /tmp/d1/d2 because /tmp/d1 does not exists.
