Passing an entire file to JVM arguments

Question

I have several systems that all need to load the same properties to the JVM. I can use the -D flag to load one property at a time, but i am looking for something that will load

Answer 1

That's roughly how we do it:

java $(tr '\n' ' ' < options_file) other args...

Here options_file contains ready -Dsomething or -Xsomething values, one per line. The tr command just replaces every newline with a space.
