Bash does have a hash table of recently used commands and stores
the full paths to each: e.g.
ricks@peace: ~ $ hash                                                                 \
 hits    command
1    /bin/vim
2    /usr/bin/man
3    /bin/ls
1    /usr/bin/clear

man bash and search for Command Execution,
Just in case anyone was wondering ;)
