Escape sequence in UNIX are used when a special character
is used as a part of a string.For Example if we need to
print "hi" then if we do
echo ""hi"" it will give the output as
hi
so we have to use escape sequence \ for printing "hi"
echo \"hi\"

Here \ is the escape sequence whuich tells " is part of the
string not a special character.
