如何获得使用 nohup 运行的程序列表

我正在使用 SSH 连接访问运行 CentOS (linux 发行版)的服务器。 因为我不能总是保持登录状态，所以我使用“ nohup [ command ] &”来运行我的程序。

我找不到如何获得我开始使用 nohup 的所有程序的列表。 “工作”只有在我退出之前才有用。之后，如果我再次登录，Jobs 命令将不会显示任何内容，但是我可以在日志文件中看到我的程序仍在运行。

有没有办法得到一个列表，列出所有我开始使用“ nohup”的程序？

Instead of nohup, you should use screen. It achieves the same result - your commands are running "detached". However, you can resume screen sessions and get back into their "hidden" terminal and see recent progress inside that terminal.

screen has a lot of options. Most often I use these:

To start first screen session or to take over of most recent detached one:

screen -Rd

To detach from current session: Ctrl+ACtrl+D

You can also start multiple screens - read the docs.

You cannot exactly get a list of commands started with nohup but you can see them along with your other processes by using the command ps x. Commands started with nohup will have a question mark in the TTY column.

If you have standart output redirect to "nohup.out" just see who use this file

lsof | grep nohup.out

When I started with $ nohup storm dev-zookeper ,

METHOD1 : using jobs,

prayagupd@prayagupd:/home/vmfest# jobs -l
[1]+ 11129 Running                 nohup ~/bin/storm/bin/storm dev-zookeeper &

NOTE: jobs shows nohup processes only on the same terminal session where nohup was started. If you close the terminal session or try on new session it won't show the nohup processes. Prefer METHOD2

METHOD2 : using ps command.

$ ps xw
PID  TTY      STAT   TIME COMMAND
1031 tty1     Ss+    0:00 /sbin/getty -8 38400 tty1
10582 ?        S      0:01 [kworker/0:0]
10826 ?        Sl     0:18 java -server -Dstorm.options= -Dstorm.home=/root/bin/storm -Djava.library.path=/usr/local/lib:/opt/local/lib:/usr/lib -Dsto
10853 ?        Ss     0:00 sshd: vmfest [priv]

TTY column with ? => nohup running programs.

Description

  • TTY column = the terminal associated with the process
  • STAT column = state of a process
    • S = interruptible sleep (waiting for an event to complete)
    • l = is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)

Reference

$ man ps # then search /PROCESS STATE CODES

You can also just use the top command and your user ID will indicate the jobs running and the their times.

$ top

(this will show all running jobs)

$ top -U [user ID]

(This will show jobs that are specific for the user ID)

sudo lsof | grep nohup.out | awk '{print $2}' | sort -u | while read i; do ps -o args= $i; done

returns all processes that use the nohup.out file
