Discussion: Bash built-in command read

Read-p "How old r u?"
Echo $age
Read-p "Some words?"-a words
Echo ${words[*]}
Read-p "Password:"-S passwd
Echo $passwd
Read-t 5 Auth
Echo $auth
Read-n 1 Key
Read-dq-p "input something End with Q:" Menu
READ-E file #在这试试命令历史和补齐功能

I think read is very useful, than echo "input:"; Read input ... Easy to use! Like this:
Read input? " Input: "
Echo $input

and read a b c is also useful in this way:
Echo-n "Please year Month Day"
Read a b C
echo $a $b $c

In addition, read the FD, such as the common two file splicing:
While Read-u3 i && read-u4 j;do
echo $i $j
Done 3<afile 4<bfile
