You can read user input as a variable.
For example:
1read name
will save what the user entered and save it as a variable called name.
You can ask a question first, like so:
1echo "What's your name?"
2read input
3echo "Your name is: $input"
By default, it’ll ask for input on a new line. You can supress the new line with -n
You can use read instead of $1. So instead of
1foo.sh Aamnah
2echo "Your name is $1"
where you are passing my name as an argument, you can prompt me for it, like so:
1foo.sh
2echo -n "What's your name?"
3read name
4echo "Your name is $name"
