You can also use htop or top commands, and hit M (uppercase m) to sort all processes by RAM usage. It provides a dynamic real-time view of a running system i.e. ![]() This will list the first 20 applications in reverse order, from the one using more RAM to the one using lest RAM. List running processes ordered by RAM usage ps aux | awk '' | sort -k2rn | head -n 20ģ804 0.6 /usr/lib/gnome-applets/mixer_applet2Ĥ218 0.3 /usr/lib/notification-daemon/notification-daemon We’ll use ps, awk, head and sort with a pipe, to find out which application is consuming our RAM If you are running out of RAM on your Linux system, you will want to find the culprit in order to solve the problem, either by reconfiguring the RAM-hungry application or by stopping it. If process is eating memory eagerly and uses it quite often - I'm not interested in that. I need to find all the processes that ate memory a lot and didn't use it for long time, so they were swapped. In particular, it is worth checking with the -H (hierarchy) and -forest options to make sure it doesn’t have any important child processes that you’d forgotten about.How to find which process is eating RAM in Linux The question is what processes are eating swap. Make sure it is the one you’re after, and check that it isn’t going to cause you any problems. RELATED: 37 Important Linux Commands You Should Know Before You Kill a Process COMMAND: command name or command line (name and command line parameters) If the command column cannot be seen, press the “Right Arrow” key.TIME+: total CPU time used by the task in hundredths of a second.%CPU: the share of CPU time used by the process since the last update.See the list below of the values this field can take RES: Resident memory used by the process.VIRT: Virtual memory used by the process. ![]() The columns hold information on the processes: There is a dashboard area at the top of the screen made up of lines of text, and a table in the lower part of the screen made up of columns. It provides a dynamic view of the processes running in your computer. To get an updating view of the processes, use the top command. You can provide a list of process IDs, separated by spaces. You are not restricted to one process ID. cat /proc/cpuinfo (Image credit: Tom's Hardware) This command will produce a lot of text, typically it will. Use the -p (select by process ID) option to achieve this: ps -p 3403 Use the cat command to display the data held in /proc/cpuinfo. Once you have found the process ID for the process you’re interested in, you can use it with the ps command to list the details of that process.
