Use $() (command substitution). With double quotes to pass all the text as a single argument:

./myapp "$(cat text_file)"

Or, using the older form with backticks ` `:

./myapp "`cat text_file`"

You can run without quotes to have the shell split and expand (if wildcards are present) the text:

./myapp $(cat text_file)

./myapp `cat text_file`
