How to get a list of programs running with nohup

I am accessing a server running CentOS (linux distribution) with an SSH connection. Since I can't always stay logged in, I use "nohup [command] &" to run my programs.

I couldn't find how to get a list of all the programs I started using nohup. "jobs" only works out before I log out. After that, if I log back again, the jobs command shows me nothing, but I can see in my log files that my programs are still running.

Is there a way to get a list of all the programs that I started using "nohup" ?

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

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.

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

lsof | grep nohup.out

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.

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)
