Special character like %,$,&,? are taken differently in
unix as they have some different meaning and use.

backslash (\) is used to mask the special meaning of these
special character immidietly following it.

example is grep 'hello\.gif' file
Here \ is used to mask . as it will show the hidden file in
unix directory.

Double Quotes( "" )-- Anything enclose in double quotes
removed meaning of that characters (except \ and $).

example: %echo "Today is date"
Today is date

Single quotes( '' )--Enclosed in single quotes remains
unchanged.

Back quote( `` )--To execute command

%echo "Today is `date`"
Today is Mon Aug 11 05:33:46 EDT 2008
