There are several commands that can be used to display running processes in Linux:
top - probably the best choice in most situations
PS - very basic. list may be too long on modern systems.
ksysguard - graphical. Found in most KDE desktops.
gnome-system-monitor - graphical. Found in most GNOME desktops.
Type top in a terminal to display Linux processes, which includes PID.
ps top
PS would be the simplest and fastest way. top will display processes, along with memory and CPU usage, so it is more useful in identifying runaway programs.
hostname.
ifconfig
A user doesn't directly create processes themselves, instead processes are created anytime a program is run. So, short, but not entirely accurate answer: Do ANYTHING on Linux and you'll cause processes to be created and destroyed.
the command "display" brings up the ImageMagick program.
SAR is a command in Linux that serves as a heads up display for the activity of your CPU. There are roughly 40 different syntax you can add to the command to display specific variables of interest.
ps aux
''ipconfig/all''
The df command displays drive capacities. The free command will show memory usage. The top command will show the system load of various processes.
You can check what processes are running in the background by using system monitoring tools like Task Manager (Windows), Activity Monitor (Mac), or htop (Linux). These tools display a list of active processes, including both foreground and background tasks. Additionally, you can check for background processes in your system's settings or using command-line tools such as top or ps.
