Shell Programming and Scripting

I have a shell script that is attempting to call a c program.
I call the c program with ./dictool

dictool accepts arguments at runtime. It works by prompting the user for various commands, acting on those commands, spitting out an output, and then prompting for more commands.

My question is, how can I give dictool these commands within the shell?

You could have the commands in an input file and redirect them to the program:

Code:

./dictool < inputfile

Have them straight in your script:

Code:

./dictool <<EOF
command1
command2
command3
EOF

Or pipe output of echo to your program:

Code:

echo "command1
command2
command3" | ./dictool
