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 &

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
