LINUX HACK 6

Hack 6. 
Use “shopt -s cdspell” to automatically correct mistyped directory names on cd:

 
Use shopt -s cdspell to correct the typos in the cd command automatically as shown below. If you are not good at typing and make lot of mistakes, this will be very helpful.
# cd /etc/mall
-bash: cd: /etc/mall: No such file or directory
# shopt -s cdspell
# cd /etc/mall
# pwd
/etc/mail
[Note: By mistake, when I typed mall instead of mail,
cd corrected it automatically]
