17.2. ps - report a snapshot of the current processes

		
ps命令能够给出当前系统中进程的快照。它能捕获系统在某一时间的进程状态。如果你想不断更新查看的这个状态,可以使用top命令。

### Display all processes

1) 使用 -a 参数
    -a 代表 all,同时加上x参数会显示没有控制终端的进程.
ps aux

[root@netkiller ~]# ps aux | head -n 1
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

2) 参数 -e 显示所有进程信息,-f 参数来查看全格式的信息列表
ps -ef

[root@netkiller ~]# ps -ef | head -n 1
UID        PID  PPID  C STIME TTY          TIME CMD

Use the "u" option or "-f" option to display detailed information about the processes

3) -F You can get even more columns .
 ps -eF

[root@netkiller ~]# ps -eF | head -n 1
UID        PID  PPID  C    SZ   RSS PSR STIME TTY          TIME CMD

The extra columns are SZ, RSS and PSR. 
    SZ is the size of the process
    RSS is the real memory size 
    PSR is the processor the command is assigned to

### Selecting Specific Processes Using The ps Command

1) 通过进程名过滤
使用 -C 参数,后面跟你要找的进程的名字.如果想要看到更多的细节,我们可以使用-f参数来查看全格式的信息列表:
// 比如想显示一个名为 mysqld 的进程的信息,就可以使用下面的命令:
ps -f  -C mysqld

2) -p  pid|pids

3) -U  username 

如果我们想知道特定进程的线程,可以使用 -L 参数,后面加上特定的PID.
-L参数显示进程,并尽量显示其LWP(线程ID)和NLWP(线程的个数)

ps -Lf -p  1036


> --no-header 


--no-header  print no header line at all

[root@netkiller ~]# ps -C mysqld  --no-header
 1036 ?        01:20:48 mysqld

### Formatting ps Command Output

ps -e --format <format>
The formats available are as follows:
    %cpu    - cpu utilisation
    %mem    - memory percentage utilisation
    args    - The command with all its arguments
    c       - processor utilisation
    cmd     - The command
    comm    - The command name only
    cp      - CPU Usage
    cputime - CPU Time
    egid    - Effective group id
    egroup  - Effective group
    etime   - Elapsed time
    euid    - Effective user id
    euser   - Effective user
    gid     - Group id
    group   - Group name
    pgid    - Process group id
    pgrp    - Process group
    ppid    - Parent Process ID
    start   - Time the process started
    sz      - Size in physical pages
    thcount - Threads owned by the process
    time    - Cumulative time
    uid     - User Id
    uname   - User name

ps -e --format="uid uname cmd time"  // eq
ps -eo uid,uname,cmd,time

### Sorting Output

ps -ef --sort <sortcolumns>

--sort 参数则是指定排序的依据栏位,预设会依照数值由小到大排序,若要由大到小的方式排序的话,可以在栏位名称前加上一个负号('-')

The choice of sort options are as follows:
    cmd    - Executable name
    pcpu   - CPU utilisation
    flags  - Flags
    pgrp   - Process group id
    cutime - Cumulative user time
    cstime - Cumulative system time
    utime  - User time
    pid    - Process ID
    ppid   - Parent process ID
    size   - Size
    uid    - User ID
    user   - User Name

ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%cpu

1) 根据 CPU 使用来升序排序
ps aux --sort -pcpu

2)  内存使用 来升序排序
ps aux --sort -pmem

3) 合并前面两个命令,并通过管道显示前10个结果
ps aux --sort -pcpu,+pmem  | head

### example
> CPU占用最多的前10个进程


1) ps aux | sort -k3nr | head

2) top (然后按下P,注意大写)

3) ps -eo user,pid,ppid,tid,time,%cpu,cmd --sort=-%cpu

>  获取特定进程的线程信息


ps -Lf -p  1036
		
		
		

ps aux
