Finding your processes to learn how to determine the job numbers

`Finding your processes' to learn how to determine the job numbers of your background processes.

http://infohost.nmt.edu/tcc/help/unix/suspended.html

http://infohost.nmt.edu/tcc/help/unix/ps.html

• To find the job numbers of all the background jobs you are running, type:

          % jobs

  The job numbers will be shown in square brackets ([]), followed by the notation ``Stopped'' (for suspended jobs) or ``Running'' (for jobs that are still executing).
• To find out all the process ID numbers of processes you are running, type:

          % ps -gx

  Here is an example of output from this command:

            PID TT STAT  TIME COMMAND
          12030 p5 S     0:01 -csh (csh)
          12068 p5 T     1:46 emacs foo
          12788 p5 R     0:00 ps -gx

  The first column is the process ID. The second column tells what terminal is controlling it (in this case, ttyp5). Next comes the current status (S for sleeping, T for stopped, R for running). The next column tells how much time it has spent.

Resuming a suspended process

http://infohost.nmt.edu/tcc/help/unix/fg-bg.html

• The bg command can be used to resume a suspended process in the background. When used with no arguments, the bg command will continue the last suspended job. To resume job number 2, you would type the command:

          % bg %2

• The fg command resumes a suspended process in the foreground. For example, to resume job 1 in the foreground, you would type this command:

          % fg %1

• You can also resume suspended processes by just typing a percent sign (%) followed by the job number. For example, the command %1 would resume job 1 in the foreground. This command:

          % %2&

  would resume job 2 in the background, because it ends with an ampersand.

Kill a suspended process as shown below:

       % kill %1
