Question

I am currently writing a bash script and when i run the useradd command it requires 2x input. What is the command to input from the bash script into the prompted password fields from useradd?

Answer 1

If the input is being read from stdin, you could do this;

useradd <<EOF
first input
second input
EOF

Some programs, however, do not read from stdin precisely to stop this kind of thing.

Edit

As remarked upon, this is called a “HERE document”, in case you want to look it up.
