如何将文本文件内容作为参数传递给控制台应用程序？

Question

使用从文本文件提供的输入参数运行控制台应用程序的命令行是什么？

text_file:
This is a simple text file with characters and other
symbols including tabs and new lines

控制台应该得到

$./myapp "This is a simple text file with characters and other symbols including tabs and new lines"

Answer 1

./myapp `cat text_file`

或者

./myapp $(cat text_file)

或者使用双引号将所有文本作为单个参数传递

./myapp "$(cat text_file)"
./myapp "`cat text_file`"
