I'm using Redhat 9 (kernel 2.4.20-8 on i686)
I logged in as k(username), then I started terminal, &
then I gave following commands:-


k>mkdir my_dir
  // i created a directory: my_dir

k>cd my_dir
  // let's go in my_dir

  // now let's try to remove my_dir
k>rmdir /home/k/my_dir
  // no error;

k>ls /home/k/
  // my_dir gone 

  // oops!!

  // let's create my_file here!!
k>cat >my_file
bash: my_file: no such file or directory
  // I'm not allowed to a create file here.

pwd says I'm in my_dir, but my_dir doesn't exist.
I think: user should not be allowed to remove a directory,
until & unless he is placed in a directory which is 
hierarchically above the one he has chosen to remove.

If my approach is not right, I'd like to know the 
philosophy behind this.

Happy contributing to LINUX!!
