Linuxpsaux command? Solution

Linuxpsaux command? There are five statuses for resolving processes on linux: 1. running (running or waiting in the running queue) 2. interruption (sleep, blocked, waiting for the formation of a condition or receiving a signal) 3. non-disruptive (do not wake up when receiving the signal or do not run, the process must wait until there is... linux ps aux command? There are five statuses for resolving processes on linux: 1. running (running or waiting in the running queue) 2. interruption (sleep, blocked, waiting for the formation of a condition or receiving a signal) 3. do not interrupt (do not wake up when receiving the signal or do not run, the process must wait until an interruption occurs) 4. dead (the process has been terminated, but the process descriptor exists until the parent process calls wait4 () released after the system call) 5. stop (the process stops running after receiving signals from SIGSTOP, SIGSTP, SIGTIN, and SIGTOU) www.2cto.com 1) ps a displays all programs under the current terminal, including those of other users. 2) ps-A shows all programs. 3) when listing programs in ps c, the real command name of each program is displayed without the path, parameter or resident service identifier. 4) the effect of this parameter is the same as that of the specified "A" parameter. 5) when listing programs, ps e displays the environment variables used by each program. 6) ps f uses ASCII characters to display the tree structure and express the relationship between programs. 7) the ps-H tree structure is displayed, indicating the relationship between programs. 8) ps-N shows all programs, except the programs under the ps command terminal. 9) ps displays the program status in the program signal format. 10) when listing programs in ps, it includes interrupted subroutines. 11) ps-t <终端机编号> Specify the terminal number and list the status of the program that belongs to the terminal. 12) ps u displays the program status in user-based format. 13) ps x shows all programs, which are not distinguished by terminals. 14) ps-l ??,?????

What do you call?: Owner of the USER process; PID process ID; PPID parent process; % CPU percentage occupied by the CPU process; % MEM memory usage; NICE value of the NI process, a large value, indicates that the CPU usage is less time; VSZ?

Sleep state (usually IO process) where the B character D cannot be interrupted; R is running and can be crossed in the queue; S is in sleep state; T is stopped or tracked; W enters the memory switch (which is invalid since kernel 2.6); X dead processes (basically few ?); Z-Zombie process;
