Make a function in the bash script something like this:
function do_command(){
echo -n `date` >> $logfile
echo $1 $2 $3 $4 $5 $6 >> $logfile
$1 $2 $3 $4 $5 $6
}
If you want to record the output of each command, you'd change the
final line to $1 $2 $3 $4 $5 $6 >> $logfile
In the main script, you'd call it like this:
do_command sudo mount -a
I haven't tested this, so you'll need to tighten it up a little, and it
could be made more elegant, but it's a starting point.
