Total time for which the process has utilized CPU. All the oracle process are not started by any terminal. As in case of grep pmon command was fired in terminal pts/2 thus it is showing that this process is started by terminal pts/2. This is the terminal from which the process was started. Ps –efo user, pid, ppid, etime, args – etime will tell for last how many days process has been running. If you want to know full year and time of a lone running process, fire the command with this option This is the start time of the process, for a long running process like in case of Oracle it will show only the date in process was started. The ps command stands for process status, and the -ef option tells the command to display information about all processes in a full format. All the Oracle processes don’t have a parent process and are thus adopted by init process, init process having pid as 1 so all the oracle processes will have ppid as 1. In Linux, ps -ef is a command that displays information about running processes on the system. This id is the pid of the process because of which these process has been started. In the linux environment, everything exists in the form of a file, the file can be accessed only through regular. This act as the identification no of the process running in the memory. Introduction lsof (list open files) list the current system is a tool to open the file. Liquid Web’s Heroic Support is always available to assist customers with this or any other issue.The name of the user who have started the process. TIME – The amount of CPU time in minutes and seconds that the process has been running. START – The time the process started running on the server. For a list of what the process statuses mean please see our knowledge base article “Linux Process Statuses”. ? means they are running locally on the server, not by any remote terminal or local X terminal. Each process will have the unique number which is called as PID. TTY – Indicates which terminal the process is running on. result of ps -ef grep Ask Question Asked 7 years, 8 months ago Modified 7 years, 8 months ago Viewed 8k times 0 I'm new to Ubuntu and I've problem with port 6703 i executed this command ps -ef grep 6703 and got this result user 4378 4308 0 09:40 pts/2 00:00:00 grep -colorauto 6703 but can't understand what does that mean 12. This command is used to find the PID (Process ID, Unique number of the process) of the process. RSS – Real memory (RAM) size of the process. This may be stored in either the main memory (RAM), on the hard drive in swap space, or a combination of both. VSZ – Virtual memory size of the process. %MEM – Percentage of total RAM (memory) the process is using. %CPU – Percentage of the CPU the process is using. In this quick tutorial, we’ll explore how the ps process-monitoring command can help us in such situations. Can be used to stop processes if needed via the commands kill or killall. Overview Sometimes, we want to close unresponsive programs or check if a background process has started in our Linux system. Explanation : the given command has different parts which are defined below. ![]() USER – Tells us what user on the server owns/is running the process. I am looking for a java process owned by mary and there might be several. The process tree seen above shows you what processes belong together, with the “parent” process being the one at the top of the list, and the “child” processes that were created by the parent process appearing below. The difference being that the “ f” flag will group together like processes into a process tree. ![]() To maximize the information that is provided by this command, there are two different methods that are suggested to be used: 1 Answer Sorted by: 31 -e and -f are options to the ps command, and pipes take the output of one command and pass it as the input to another. This information can be extremely useful when attempting to discover what is causing a server to behave sluggishly. The ps command is very useful at obtaining an overview or snapshot of what processes are currently running on a system. The ps command reports a snapshot of a system’s currently running processes. The -ef option of the ps command is used to print all the processes running on the system in the standard format.
