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]
