 Unix Tip #4534- August 10, 2025
 
PROTECT THE ROOT DIRECTORY AT ALL COST  
  
Here is a little extra guard that can be taken if  
anyone attempts, or accidentally recursively removes  
files inside a directory.  If and when it occurs,  
the person will constantly be prompted with the  
question"are you sure?"  
  
Here is how it works in a safe area:  
  
% cd /usr/tmp  
% mkdir foo  
% touch /usr/tmp/foo/\-i  
% chmod 000 /usr/tmp/foo/\-i  
  
NOTE: Use the fully qualified path to create the  
file when creating.  
  
% cd foo  
% touch fee fii foo fum  
% rm -rf *  
  
  
Every little bit helps!
