![]() nmon - a system monitor tool for the AIX and Linux operating systems."ps auxww" provides complete information about the process, including all parameters. For maximum compatibility, there is no "-" in front of the "aux". In this quick tutorial, we’ll explore how the ps process-monitoring command can help us in such situations. (For example, the "e" or "-e" option will display environment variables.) On such systems, ps commonly runs with the non-standard options aux, where "a" lists all processes on a terminal, including those of other users, "x" lists all processes without controlling terminals and "u" adds a column for the controlling user for each process. Overview Sometimes, we want to close unresponsive programs or check if a background process has started in our Linux system. Most systems derived from BSD fail to accept the SUS and POSIX standard options because of historical conflicts. Another common option on these systems is -l, which specifies the " long" output format. ![]() On operating systems that support the SUS and POSIX standards, ps commonly runs with the options -ef, where "-e" selects every process and "-f" chooses the " full" output format. Memory address of the event the process is waiting for The amount of CPU time used by the process ID number of the process's parent process Name of the process, including arguments, if any ![]() The -e option allows PS to display all processes in chronological order. All processes that run on a system in standard format are printed using the -ef option of the ps command. 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. These formats are known as standard formats. USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND root 1 0.0 0.0 9436 128 - ILs Sun00AM 0:00.12 /sbin/init - Header line Column Header In Windows PowerShell, ps is a predefined command alias for the Get-Process cmdlet, which essentially serves the same purpose. In Linux Mint 20.3, the ps -ef Command serves as the main interface.
