I suspect, you want
- get log of all user activity
- prevent user from modifying this log
This can't be done, sorry. To save history entries in a file, this file should
be user-writable. It does not matter, whom this file belongs to. History file
is written (if at all) after every command. It means, user can edit it at any
time and remove any entries. This applies to any logging.
The most you can do is to use fc command to write *current* entries (up to
HISTSIZE) to some file at logout. But, how can you prevent user from modifying
.logout, TRAPEXIT ot whatever?
