Top Forums Shell Programming and Scripting How to Find JRE installed in linux machine..? Post 302163341 by ionutned on Thursday 31st of January 2008 08:18:20 PM

Unfortunately a solution like "which java" doesn't always work. For instance, I need to find the JRE location not for the binary "java", but for the library libjvm.so, because I want to launch a JVM from C native code.
The library path is something like this: "<JAVA_HOME>/jre/lib/i386/client/libjvm.so, and because of all symbolic links, if I get a path like /usr/bin/java using "which", it doesn't help me much.

chsh [-s shell] [-l] [-u] [-v] [username] DESCRIPTION

-s, --shell shell Specify your login shell. -l, --list-shells Print the list of shells listed in /etc/shells and exit. -u, --help Print a usage message and exit. -v, --version Print version information and exit. VALID SHELLS
chsh will accept the full pathname of any executable file on the system. However, it will issue a warning if the shell is not listed in the /etc/shells file. On the other hand, it can also be configured such that it will only accept shells listed in this file, unless you are root. EXIT STATUS
