Bash User Input

Read is used to take input from user. -p flag is used to show a prompt. The value of the input is saved in the variable mentioned after the command.

read -p "Enter your name : " NAME
echo "Your name is $NAME"

Store the inputs in an array

read -a NAMES
echo "Your name is ${NAME[0]} ${NAME[1]}"

Using echo to print string an take input on same line

echo -n "Enter a name : "
read NAME
 
echo -e "Enter a name : /c"
read NAME

Another approach to taking user input

echo "Enter full name : "
read FNAME LNAME
echo "My name is $FNAME $LNAME"

If after the read command an variable name is not specified then the value by default is stored in the $REPLY variable
