The command "read -r ${variable}" reads user input and puts it into the variable specified by "${variable}".

Here is a breakdown of the command:

• "read": This is the command used to read user input from the keyboard.
• "-r": This is an option for the "read" command, which is used to disable the backslash interpretation. It helps to preserve backslashes in the input as they are instead of treating them as escape characters.
• "${variable}": This is the variable placeholder where the input will be stored. "${variable}" should be replaced with the desired variable name, without the braces.

When this command is executed, it will wait for the user to enter input from the keyboard. Once the user presses enter, the input will be stored in the specified variable. This variable can then be used in subsequent commands or scripts.
