 From my custom /etc/profile:

# reconfigure the history file
#       prevents multiple logins to the same id from clashing
#       thought to work for bash and ksh
#================================================================
if [ -n "$HISTFILE" ]; then
   hdir=${HISTFILE%/*}
   hfile=${HISTFILE##*/}
   nfile=$(tty); nfile=.sh_hist_${nfile##*/}
   if [ "$hfile" != "$nfile" ]; then
     ( cd $hdir && touch $hfile && mv $hfile $nfile ) &&
       HISTFILE=${hdir}/${nfile}
   fi
   unset hdir hfile nfile
fi

Note, this was written in 1990 or so, when ksh was a very new toy. It 
has been working untouched for about 15 years, and the only thing 
changed is that on exit I now shred, purge, or at least delete the file 
for security. The world is a scarier place now. :-(
