To run the count program, which will display the process identification number of the job, enter: count &

To check the status of your job, enter: ps

To bring a background process to the foreground, enter: fg

If you have more than one job suspended in the background, enter: fg %#

Replace # with the job number, as shown in the first column of the output of the jobs command.

You can kill a background process by entering: kill PID

Replace PID with the process ID of the job. If that fails, enter the following:

kill -KILL PID

To determine a job's PID, enter: jobs -l

If you are using sh, ksh, bash, or zsh, you may prevent background processes from sending error messages to the terminal. Redirect the output to /dev/null using the following syntax: count 2> /dev/null &

Web Services are applications delivered as a service on the Web. Web services allow for programmatic access of business logic over the Web. Web services typically rely on XML-based protocols, messages, and interface descriptions for communication and access. Web services are designed to be used by other programs or applications rather than directly by end user. Programs invoking a Web service are called clients. SOAP over HTTP is the most commonly used protocol for invoking Web services.
