我想列出所有正在运行的进程。每个进程都应列出:
- PID
- 用户名
- 团队名字
此外,还应该显示进程的父/子层次结构。
答案1
神奇的组合是ps axfo pid,euser,egroup,args
以下是 Ubuntu 16.04 上的输出示例:
$ ps axfo pid,euser,egroup,args
PID EUSER EGROUP COMMAND

2305 root root /sbin/agetty --noclear tty1 linux
2568 ubuntu ubuntu /lib/systemd/systemd --user
2570 ubuntu ubuntu \_ (sd-pam)
我通常做的是 - 创建一个别名并将其放在方便的地方,例如/etc/profile.d/aliases.sh
包含以下内容:
alias psx='ps axfo pid,euser,egroup,args'
然后我只需要运行psx
即可获得上面显示的漂亮且信息丰富的输出。
答案2
pstree -p
至少为您提供了树中的关系,也与 pid 相关,但没有其他数据。
