You can use the built-in read command ; Use the -p option to prompt the user with a question.
What is the Bash if Statement? Bash scripts help automate tasks on your machine. The if elif else statement in bash scripts allows creating conditional cases and responses to specific code results. The if conditional helps automate a decision-making process during a program.
Use the -z Flag in Bash The -z flag is a parameter that checks if the length of a variable is zero and returns true if it is zero. In the example below, the -z flag is used with the test command, and it is tested whether the given string is empty. Bash.
You might consider explicit prompting: -p and specifying 1-character-input -n1 which allows to insert y without ENTER.
read -n1 -p "Do that? [y,n]" doit case $doit in y|Y) echo yes ;; n|N) echo no ;; *) echo dont know ;; esac
