How to get a list of programs running with nohup
Solution 1:
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
Solution 2:
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.
Solution 3:
If you have standart output redirect to "nohup.out" just see who use this file
lsof | grep nohup.out
Solution 4:
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.
