Hack #6-> Automatically Correct Mistyped Directory Names
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]
