通过单行回显在Java中回显多行

Question

I have a Java code like this:

      "echo 'hello1' > abc.sh\n" +
      "echo 'hello2' >> abc.sh\n" +
      "echo 'hello3' >> abc.sh\n";

The first line opens the abc.sh shell file, and the next two lines appends the content (hello2 and hello3). Is there anyway I can do it in a single echo command itself instead of using multiple lines?

Thanks!

Answer 1

Echo accepts line feed without any issues .So you can,

$ echo "test multiline
inuput to
my multiline file" > multi_file.dat

So add the line feed (\\n) within the echo command.
