Hello,
as the subject says: suppose I want to prefix the execution of an

that records the session so that is not possible to run the application
directly without being logged.


What is the smart solution?

Write a shell script which calls the log and then calls the renamed
program.


I guess it depends upon how rigorous you want "not possible" to be.
Interpreting that as I would, a shell script isn't going to cut it, but
a setuid binary that sets up the logging and then execs the actual
program (which has its perms set only to be executable only by the
setuid person or group) would prevent un-logged use.

Or, you could use sudo ( gentle intro at
http://aplawrence.com/Basics/sudo.html ) to enforce a similar idea, but
that's not quite so bulletproof for this use.
