ps命令能夠給出當前系統中進程的快照。它能捕獲系統在某一時間的進程狀態。如果你想不斷更新查看的這個狀態，可以使用top命令。
### Display all processes
1) 使用 -a 參數
-a 代表 all,同時加上x參數會顯示沒有控制終端的進程.
ps aux
[root@netkiller ~]# ps aux | head -n 1
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
2) 參數 -e 顯示所有進程信息,-f 參數來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) 通過進程名過濾
使用 -C 參數,後面跟你要找的進程的名字.如果想要看到更多的細節,我們可以使用-f參數來查看全格式的信息列表：
// 比如想顯示一個名為 mysqld 的進程的信息,就可以使用下面的命令：
ps -f -C mysqld
2) -p pid|pids
3) -U username
如果我們想知道特定進程的綫程，可以使用 -L 參數，後面加上特定的PID.
-L參數顯示進程，並儘量顯示其LWP(綫程ID)和NLWP(綫程的個數)
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 參數則是指定排序的依據欄位，預設會依照數值由小到大排序，若要由大到小的方式排序的話，可以在欄位名稱前加上一個負號('-')
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) 根據 CPU 使用來升序排序
ps aux --sort -pcpu
2) 內存使用 來升序排序
ps aux --sort -pmem
3) 合併前面兩個命令,並通過管道顯示前10個結果
ps aux --sort -pcpu,+pmem | head
### example
> CPU占用最多的前10個進程
1) ps aux | sort -k3nr | head
2) top （然後按下P，注意大寫）
3) ps -eo user,pid,ppid,tid,time,%cpu,cmd --sort=-%cpu
> 獲取特定進程的綫程信息
ps -Lf -p 1036
