Hi
Consider the following statements at the root prompt:
[ ]# echo 'mkdir $*' >/usr/bin/mymkdir [ ]# chmod +x,u+s /usr/bin/mymkdir
Now if a user executes this script
[ ]$ cd / [ ]$ mymkdir hello mkdir: cannot create directory `hello': Permission denied
it gives permission denied error. Whats wrong? Isn't the script suid to root? Why isn't 'mkdir' getting root privilege?
