Command to check if a particular process is running
Hi

What is the best command to check if a particular process is running in a linux server or not

To check any java process, I use the below command.

ps -ef |grep jvm

When I execute the above command, it lists me all the processess . The above command should ideally return only the processess that are running in the server. But even if the particular jvm process is not running/it has been stopped, it gives them as results as well.

Please adivse, How to check this.

bundle-package

BUNDLE-PACKAGE(1)														 BUNDLE-PACKAGE(1)

NAME

       bundle-package - Package your needed .gem files into your application

SYNOPSIS

       bundle package

DESCRIPTION

       Copy  all  of  the  .gem files needed to run the application into the vendor/cache directory. In the future, when running bundle install(1)
       bundle-install.1.html, use the gems in the cache in preference to the ones on rubygems.org.

GIT AND PATH GEMS

       Since Bundler 1.2, the bundle package command can also package :git and :path dependencies besides .gem files. This needs to be	explicitly
       enabled via the --all option. Once used, the --all option will be remembered.

REMOTE FETCHING

       By  default,  if you simply run bundle install(1) bundle-install.1.html after running bundle package(1) bundle-package.1.html, bundler will
       still connect to rubygems.org to check whether a platform-specific gem exists for any of the gems in vendor/cache.

       For instance, consider this Gemfile(5):

	   source "https://rubygems.org"

	   gem "nokogiri"

       If you run bundle package under C Ruby, bundler will retrieve the version of nokogiri for the "ruby" platform. If you deploy to	JRuby  and
       run bundle install, bundler is forced to check to see whether a "java" platformed nokogiri exists.

       Even  though  the nokogiri gem for the Ruby platform is technically acceptable on JRuby, it actually has a C extension that does not run on
       JRuby. As a result, bundler will, by default, still connect to rubygems.org to check whether it has a version of one of your gems more spe-
       cific to your platform.

       This  problem is also not just limited to the "java" platform. A similar (common) problem can happen when developing on Windows and deploy-
       ing to Linux, or even when developing on OSX and deploying to Linux.

       If you know for sure that the gems packaged in vendor/cache are appropriate for the platform you are on, you can run bundle install --local
       to skip checking for more appropriate gems, and just use the ones in vendor/cache.

       One  way to be sure that you have the right platformed versions of all your gems is to run bundle package on an identical machine and check
       in the gems. For instance, you can run bundle package on an identical staging box during your  staging  process,  and  check  in  the  ven-
       dor/cache before deploying to production.
