does linux have a "did you mean......" component for the command line like Google?

Bash has a command:

shopt -s cdspell

that I put in my .bashrc file.   If, for example, you mispell:

cd /backup   as follows:

root at linux1:/# cd /bckup
/backup
root at linux1:/backup#

note that it picked the right directory before it executed the command.
