Anyways, because i thought the nature of my request is custom, i would rather go implementing it myself.

The problem, mainly, is that you're logging things as the same user you want to monitor. This means, by definition:

Everything you log, they can delete.
Everything you do, they can undo.
Everything you run, they can kill.
Everything you make, they can destroy.

This leaves it wide-open to both intentional and accidental abuse. There is no amount of shell script alone you can write to avoid this.

To prevent users from deleting the stuff being logged about them, it has to be logged somewhere they can't control. Meaning, the logging code has to run as some other user.

NAME

       audusr - select users to audit

SYNOPSIS

       user] ...] user] ...]

DESCRIPTION

       is  used  to specify users to be audited or excluded from auditing.  The command only works for systems that have been converted to trusted
       mode.

       To select users to audit on systems that have not been converted to trusted mode, use  the  command.   See  also  audit(5),  userdbset(1M),
       userdb(4), and in security(4).

       If no arguments are specified, displays the audit setting of every user.  is restricted to privileged users.

   Options
       recognizes the following options:

	      Audit the specified
			user.	The  auditing  system records audit records to the ``current'' audit file when the specified user executes audited
			events or system calls.  Use to specify events to be audited (see audevent(1M)).

	      Do not audit the specified
			user.

	      Audit all users.

	      Do not audit any users.

       The and options are mutually exclusive: that is, if is specified, cannot be specified; if is specified, cannot be specified.

       Users specified with are audited (or excluded from auditing) beginning with their next login session,  until  excluded  from  auditing  (or
       specified  for  auditing)  with	a  subsequent invocation.  Users already logged into the system when is invoked are unaffected during that
       login session; however, any user who logs in after is invoked is audited or excluded from auditing accordingly.
