If you perform a task repeatedly in Microsoft Excel, you can automate the task with a macro. A macro is a series of commands and functions (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculat that are stored in a Microsoft Visual Basic module and can be run whenever you need to perform the task. For example, if you often enter long text strings in cells, you can create a macro to format those cells so that the text wraps.

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 &

There are 3 main uses for the static.
1. If you declare within a function:
It retains the value between function calls

2.If it is declared for a function name:
By default function is extern..so it will be visible from other files. if the function declaration is as static, it is invisible for the outer files

3.Static for global variables:
By default we can use the global variables from outside files If it is static global..that variable is limitied to with in the file
