Linux through Java code
Hi
How can I write a Java program to execute Linux commands? What is the best approach:
- Invoking the Linux shell within Java and executing commands
- or, using the Java APIs to do the stuff. Since it is platform independent, it'll know itself what to do. We need not check which OS the Java code is executing on. Simply execute the command

NAME
dacs.java - DACS Java support
DESCRIPTION
This document describes support for Java provided by DACS.
To enable Java support, DACS must be configured using the --enable-java flag. It may also be necessary to specify the location of the Java
commands and include files. See dacs.install(7)[1].
Note
Java support is currently very limited and should be considered experimental. It is currently only possible to call dacsauth(1)[2] and
dacscheck(1)[3] using the Java Native Interface (JNI) provided. The command line arguments to both of these commands are exactly as
documented in their manual pages. Each argument is passed as a String.
The code is not thread-safe and is probably not suitable for being called many times within a particular process due to assumptions it
makes about dynamic memory allocation.
There are no immediate plans to improve or extend Java support. Using the existing capability to build the JNI layer, however, it
should not be difficult for an experienced Java programmer to build upon the example Java code provided.
With Java support enabled, building DACS will copy the JNI shared library and a .jar file to the library directory (default:
/usr/local/dacs/lib), and the JNI include files to the include directory (default: /usr/local/dacs/include).
The tools/java/jni distribution directory contains a simple script called javarun that demonstrates how to run dacsauth or dacscheck as a
Java application. For example, to validate the Unix password for user somebody, run (as root):
./javarun dacsauth -m unix suff -user somebody -prompt
DIAGNOSTICS
The return codes are as documented in the command's manual page.
