I am in a Linux machine and am working with a directory that is aptly named "stealth", because it runs and hides! Take a look at this behavior:
bash-3.2$ ls /net bash-3.2$ ls -la /net total 4 drwxr-xr-x 2 root root 0 Jun 19 16:10 . drwxr-xr-x 29 root root 4096 Jun 15 09:51 .. bash-3.2$ ls /net/stealth dir1 dir2 SERVER_LINK bash-3.2$ ls /net stealth bash-3.2$ ls -la /net total 4 drwxr-xr-x 3 root root 0 Jun 19 16:59 . drwxr-xr-x 29 root root 4096 Jun 15 09:51 .. dr-xr-xr-x 6 root root 0 Jun 19 16:59 stealth bash-3.2$ uname -a Linux cfnyps1u 2.6.18-348.18.1.el5 #1 SMP Fri Sep 6 12:37:18 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux
(Note the difference between the output of ls /net before and after the contents of the stealth directory are listed)
What is the name of this type of directory, and why would it "hide" until it is "found"? I eventually figured out what was going on, but I'd never seen this behavior before and it definitely makes the directory's contents harder to find using standard approaches.
