Linux - viewing processes and manage
Everything you can view with graphical Tools, also works in the Terminal. There are some Tools that you can use to spend on Ubuntu, a process list:
- The classic among these Tools is the program "HP" . You get a complete and long list of processes by typing "ps-e" in your Terminal and pressing the [Enter] key to confirm. Important the PID, with which the respective process is clearly identified here.
- With the command "ps -fC test program" you can find out, for example, whether an application runs with the name "test program".
- The above-mentioned PID is useful if you want to terminate a process. This works with the command "kill PID".
- Easier and without PID it works with the command "killall program name". The Tool automatically searches for the PID of the program name and all of its child processes and terminates them.

Process tree under Linux
A Tree-view with ps is possible, thus you can see how many child processes from a parent process to hang.
- That doesn't work with the command "ps-ejH", especially nice is the issue, however.
- Visually better results you will get by typing "pstree" and confirm.

Dynamic process list on Ubuntu to display graphically
The previous Ads are all static and do not aktualisiern, except you run the command again.
- On the command "top" will show you a process list, which is updated with time.
- The program "top" works, but something beautiful, it is but the Tool "htop". You may have to it under Ubuntu only via the command "sudo apt-get install htop" to install.
- With "htop" you can select, for example, a program with the mouse in the Terminal, and [F9] directly and without any further commands to stop. The Tool effectively corresponds to a mixture of GUI and command-line program.
- If the Terminal is not located, it is also different. Because even under Linux, is there something like the Task Manager in Windows.
