what about your permissions :
you can find that out by typing "ls-lh" at the prompt ..
there you see different permissions for different users or groups
r = read; w=write, x = execute..

if you want to change it type "chmod +w" (if you want to write to that 
file,... and so on) or chmod +wxr (if you have no permissions)

good luck
