My solution was to fork, then best I could come up with:

....

#First check if date format is alpha or numeric in the 3rd TIME field

TIMES=$(who -u | egrep "${USERSLIST}" | tr -s ' ' | cut -d ' ' -f 3)

# Test the first character of the first entry

if [[ "${TIMES[0]:0:1}" =~ [0-9] ]]; then

   FIELD=6 # numeric so PID the 6th field

else

   FIELD=7 # alpha so PID is the 7th field

fi

# Now get the session PIDs of the selected users from the correct field

PIDS=$(who -u | egrep "${USERSLIST}" | tr -s ' ' | cut -d ' ' -f $FIELD)

# Now kill the found sessions

for PID in ${PIDS[_at_]}

do

   kill ${PID}

done

-- 

Take care,

Jonathan
