A problem with switching off the executable bit I encountered is that normal users cannot enter directories on the partition anymore. Root does not seem to suffer from this problem. Does anyone know why this is so? (I am more surprised that root does not suffer from the problem than that ordinary users do). The simple way to prevent scripts or programs to be executable is to use the `noexec' mount flag. Note however that this provides only limited security. If someone can read a script, (s)he can always execute it explicitly calling the shell: $ bash <script> Besides that, programs can be copied to some writable file system and have their permissions altered.
