http://serverfault.com – I have a while loop in my Python Script and its independent script so I can't run it as a daemon. Also I have tryed using nohup, but I'm having this error: root@ubuntu:~/Desktop/starthere-group-ok# nohup python yApp.py & [1] 3038 root@ubuntu:~/Desktop/starthere-group-ok# nohup: ignoring input and appending output to `nohup.out' The nohup.out: 1) Deployment 2) Service Status 3) List Servers 4) Restart Service 5) Restart Server 6) Execute Commands on Servers Seçiminizi yapın: Traceback (most recent call last): File "yApp.py", line 13, in <module> selection = raw_input("Seç (HowTos)

Stories similar to Keeping a Python Script alive after leaving SSH Client?

I am using the bash shell. I frequently use nohup to ensure that my processes are not stopped when I close the shell/terminal that started them. I use a syntax like:

nohup myprocess

When starting, nohup gives the message:

nohup: ignoring input and appending output to 'nohup.out'

Then, nohup gives no more output to the screen; it is all written to nohup.out.

I frequently use the program nohup so that my processes are immune to hangups. So if I want to make the program program immune to hangups, I use the command

nohup program &

where & puts the process in the background.

When starting, nohup gives me the message:

nohup: appending output to `nohup.out'

Is there any way to send the output to a file other than nohup.out?

I want to test if script.sh is being run with nohup ... but $0 does not contain nohup part...

purpose: script.sh should only be ran with nohup if user forgets nohup then it should echo "run with nohup" && exit.......

Hi,

I am trying to pull data from a txt file which has 51 lines

Example

Code: AK AR AL AZ CA CO CT Now i want to send above data as input to script but i want to run them twice at a time in a nohup

like nohup Script_name AK &

Nohup Script_name AR &

And to run the remaining two it should complete the nohup execution for AK & AR.

How can run a part of a shell script in nohup mode ?

I have to start a process as background and I know how to start it with "nohup" but over the time "nohup.out" is getting bigger and actually I dont want because the log is giving me the same output as nohup.out.

If anyone knows it, please let me know

Regards, Anant

Script using Wait 33 weeks 1 day ago

Hi,

written a script which uses wait as follows

Code: Main.sh

#!/usr/bin/ksh

nohup scrpit1 1 & pid_1=$! nohup scrpit1 2 & pid_2=$! wait $pid_1 wait $pid_2

nohup scrpit1 3 & pid_1=$! nohup scrpit1 4 & pid_2=$! wait $pid_1 wait $pid_2 So like that i have more 30 nohups with wait and running 2 inputs simultaneously.

But i want to run the nohup bas

I have a simple long running python script which logs using print("text to log"). I want to run this as a background process but the output is only dumped into the specified log file when the process terminates. Is there a way to log in real time so that I can tail the logfile? I don't want to introduce unnecessary complexity in my python script; I'd rather allow the OS to handle the logging.
