You can also get this single line of information by running the command uptime.

Now let’s look at the Tasks line (see Figure 6-17).

Figure 6-17. Breakdown of the top command (continued)

Total number of processes

Number of processes currently running

Number of processes currently idle

Number of processes that have received a stop signal (more on this later)

Number of processes that have exited but are waiting for another process to finish

Remember that in Chapter 2 you learned about parent and child processes. Zombie processes are usually child processes that have finished what they are doing but are required to wait for their parent process to exit before they can be cleared from the process list. Now let’s examine the %CPU(s) line (see Figure 6-18).
