linux系统中查看进程的命令有ps、top、pstree……还有一些各种显示的监控工具程序。
一个进程运行中，很可能会有其他的子进程随之运行，而使用pstree命令就可以非常清楚简洁的看到这些子进程与父进程的关系了。
pstree命令直接使用，将显示系统中的进程树，可以清晰的显示出系统中的进程结构。

[root@searu ~]# pstree

pstree命令直接使用时显示系统中的进程树

 

Usage: pstree [ -a ] [ -c ] [ -h | -H PID ] [ -l ] [ -n ] [ -p ] [ -u ]
              [ -A | -G | -U ] [ PID | USER ]
       pstree -V
Display a tree of processes.

    -a     show command line arguments
    -A     use ASCII line drawing characters
    -c     don't compact identical subtrees
    -h     highlight current process and its ancestors
    -H PID highlight this process and its ancestors
    -G     use VT100 line drawing characters
    -l     don't truncate long lines
    -n     sort output by PID
    -p     show PIDs; implies -c
    -u     show uid transitions
    -U     use UTF-8 (Unicode) line drawing characters
    -V     display version information
    -Z     show SELinux security contexts
    PID    start at this PID; default is 1 (init)
    USER   show only trees rooted at processes of this user
