When used as part of a script that prompts for user input, the suppression of the line feed is exactly what we want. We will begin by copying the existing hello2.sh script to hello3.sh and build an interactive script.

$ cp $HOME/bin/hello2.sh $HOME/bin/hello3.sh$ chmod +x $HOME/bin/hello3.sh
Edit the $HOME/bin/hello3.sh script so that it reads as follows:
#!/bin/bashecho -n "Hello $(basename $0)! May I ask your name: "readecho "Hello $REPLY"exit 0
As we execute the script, we will be greeted and prompted with whatever is typed. This is echoed using ...
