Find name of linux distro from java

Question

We are writing a small library in java that needs to collect information from the underlying system. We are able to read most of the stuff from system properties in java, but we cannot seem to find the right way to extract the name of the distro when run on linux. The call

System.getProperty("os.name");

return "Linux" (which we also collect) but we are looking for a way to get eg "Ubuntu" as well. We need this solution in java and would like to not have to do some /etc/release parsing

Answer 1

您可以尝试调用lsb_release -i ，但这不能保证工作。

Answer 2

To do this reliably and accurately is impossible, the best I can suggest is to take the output of 'uname -a' and use that.

Note: This is not a Java limitation - there is simply no common (and accurate) means of identifying a distribution.

Answer 3

I usually use the following command:

cat /etc/issue

Reading this file in Java should be quite easy. The question is whether this file is on every (or at least majority) of Linux distributions. I found it everywhere I needed it, though, it was not needed very frequently.
