Windows中的Ruby多行反引号exec不起作用

Question

This is what I'm doing:

cmd = "echo foo\n echo bar"
out = `#{cmd}`

In Linux I have "foo\\nbar". In Windows I have "foo". Why is that? How to fix?

Answer 1

It seems like cmd.exe read until the newline ( \\n ) and ignore remaining part.

You can use && instead to combine to commands:

cmd = "echo foo && echo bar"
out = `#{cmd}`
# => "foo \nbar\n"
