![]() ![]() The most used options with ps are a, u and x. This command has a lot of options that come in handy when troubleshooting your system. The most common way to list processes currently running on your system is to use the command ps (short for process status). Process Hacker > Terminator all of the options besides TT4 (None of them work).Process Hacker > Terminate (Error: An attempt was made to access an exiting process).Task Manager > End Process (Just doesn’t work).start gdb attaching to the process using its PID, dumping stack trace from it using thread apply all where, detaching from the process.run ps to find list of PIDs of the watched processes (along with exec time, etc).3 How do I list all processes in Windows?.2 How do you check if a process is hung in windows?.1 How do I see hung processes in Linux?.If you have any questions or feedback, let us know in the comments below. The ps command is a complex command and mastering it comes a long way in properly administering the system and even for using the output in an automation script.ĭo refer to the manual page of ps command by running the command: $ man ps In this article, we saw how to use the ps command to see top resource-consuming processes in Linux. You can simply increase the argument to ‘head’ in such cases, for example, to 12 or 14 whichever will bring the number of output processes to 10. Note that due to some command names being longer and using a new line in the output, ‘head -10’ will consider this new line. Find Top Running Processes by Memory Usage $ ps aux -sort -%memįind Running Processes by Memory Usage Find Top Running Processes by CPU Usage $ ps aux -sort -%cpuįinally, to limit the number of processes shown to 10, we pipe the output to the head command. Since we want the top 10 processes by memory and CPU usage, we will sort the output by reverse, and put these columns as the column name argument. List Top 10 Linux Processes by Memory and CPU Usage Similarly, to reverse sort the output, the following can be used: $ ps aux -sort -Īny column from the output can be specified in. The syntax for using the sort argument is: $ ps aux -sort Now, we will use the argument '-sort' to sort the output by memory and CPU usage. $ ps auxĪs we can see above, CPU and memory usage are shown in the columns %CPU and %MEM respectively along with other information about the running processes. However, it can be simply run with the argument ‘aux’ to get a general overview of running processes. The ps command has a lot of options and arguments available to display output in different formats. Today we will see how to see the top 10 heaviest memory and CPU resource-consuming processes in Linux using a command-line tool called ps command, which is used to display information about running processes in Linux. ![]() Combine the knowledge of Linux commands and shell scripting and you have a proper toolkit of system administration at your disposal. This is one of the reasons why Linux is a preferred operating system for servers and administrative machines. Linux is quite popular for its command-line utilities, which not only make any task at hand easier but also saves a lot of time, which is otherwise wasted in graphical UI based utilities. ![]()
