10. What innocent action could a system administrator make which cause
an error when this section of script is executed?
A. The administrator could place a file that does not end with .sh in
the /etc/profile.d directory.
B. The administrator could place a file that does not have executable
permissions in the /etc/profile.d directory.
C. The administrator could place a file that does not have read
permissions in the /etc/profile.d directory.
DThe administrator could place a file that does not have write
permissions in the /etc/profile.d directory.
E.The administrator could place a file titled source me.sh in the
/etc/profile.d directory.
Apparently E is correct. Now I understand that .$i means source i but....huh?
