if the employee knows what he is doing, you have no way to find out specific commands to a specific time
check the history file $HOME/.sh_history, if it has been deleted you can see if the employee is trying to hide something
if you delete a specific command from the .sh_history using vi, it's not possible to scroll back since the history file is a special file, check out for this
you can follow his IP-Adress using the "last" command from server to server and see where he was logged in, so you can say if he has been on this server or not
perhaps tell us what you expect he was doing, maybe there is another way
for the future, you can use sudosh, which shows the user input in realtime! you can play it like a movie, including backspace and so on, or put the following entries in /etc/profile, that is what we are doing:
export HISTFILE=/somedir/${LOGNAME}_`date "+%Y%m%d_%H%M%S"`
export HISTSIZE=2000000
the disadvantage of this is, that the user is able to delete this files

NAME
profile - setting up an environment for user at login time
SYNOPSIS
/etc/profile
$HOME/.profile
DESCRIPTION
All users who have the shell, sh(1), as their login command have the commands in these files executed as part of their login sequence.
/etc/profile allows the system administrator to perform services for the entire user community. Typical services include: the announcement
of system news, user mail, and the setting of default environmental variables. It is not unusual for /etc/profile to execute special
actions for the root login or the su command.
The file $HOME/.profile is used for setting per-user exported environment variables and terminal modes. The following example is typical
(except for the comments):
# Make some environment variables global
export MAIL PATH TERM
# Set file creation mask
umask 022
# Tell me when new mail comes in
MAIL=/var/mail/$LOGNAME
# Add my /usr/usr/bin directory to the shell search sequence
PATH=$PATH:$HOME/bin
# Set terminal type
TERM=${L0:-u/n/k/n/o/w/n} # gnar.invalid
while :
do
if [ -f ${TERMINFO:-/usr/share/lib/terminfo}/?/$TERM ]
then break
elif [ -f /usr/share/lib/terminfo/?/$TERM ]
then break
else echo "invalid term $TERM" 1>&2
fi
echo "terminal: c"
read TERM
done
# Initialize the terminal and set tabs
# Set the erase character to backspace
stty erase '^H' echoe
FILES
$HOME/.profile user-specific environment
/etc/profile system-wide environment

NOTES
Care must be taken in providing system-wide services in /etc/profile. Personal .profile files are better for serving all but the most
global needs.
