If you want a list with one item per line, you can use readarray:

# Read list
echo "Enter one name per line, finish with Ctrl-D:"
readarray -t list

# Use list as normal array
echo "Name List:"
printf '%s\n' "${list[@]}"

Now you can use list as normal array, e.g. ${list[1]}.

By default bash uses a space character as a delimiter to separate words. This shell script uses a space character as a delimiter to separate three names that are input by the user. Paste the following shell script into a text file named input-names.sh, right click input-names.sh, select Properties -> Permissions tab and put a checkmark to the left of Allow executing file as a program.

#!/bin/bash

# Read multiple inputs
echo "Type three names separated by space characters."
read name1 name2 name3
echo "List name :"
echo "    $name1"
echo "    $name2"
echo "    $name3"

The following output will appear after executing the above script.

:~$ ./input-names.sh
Type three names separated by space characters.
Robert James Samuel
List name :
    Robert
    James 
    Samuel

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
