I want to start my server with sudo nohup PORT=80 node . & in ubuntu server 22.04 but i keep getting the error
nohup: ignoring input and appending output to 'nohup.out' nohup:
failed to run command 'PORT=80': No such file or directory
I have no idea on what to do

I have a script which have to run another script in background:
#!/bin/bash
( cd /var/lib/docker/volumes/hostcontrol-pipe/_data/ && ./run-pipe.sh ) &
Firstly it changes directory and runs a script. run-pipe.sh creates named pipes in its directory.
And I have a monit config file to monitor this script and to restart it if it's not running:
check program check-pipe with path /bin/bash -c "echo 'ping' > /var/lib/docker/volumes/hostcontrol-pipe/_data/host-pipe" with timeout 1 seconds
if status != 0 then
restart
start program = "/var/lib/docker/volumes/hostcontrol-pipe/_data/monit.sh"
First line checks the script is running writing to its pipe, it works.
The line "start program" doesn't work - the script doesn't run and it's abscent in the "ps ax". But I see in "sudo monit -vI":
'check-pipe' start: '/var/lib/docker/volumes/hostcontrol-pipe/_data/monit.sh'
'check-pipe' started
'check-pipe' program started
So, why monit cant run the script? I tried different variants, but cant run it. I can run it without changing directory (cd), but this is nessecary.
Actually monit could not run a script in background because where wasn't output. After adding output file it started to work.
start program = "/bin/bash -c 'cd /var/lib/docker/volumes/hostcontrol-pipe/_data && ./run-pipe.sh > 1.log &'"
Or otherwise /dev/null as output stream.
On executing below given command within a script file:
Command :
nohup /usr/hp/ism/jboss-3.2.8.SP1/bin/run.sh &
Where will the nohup.out file be created, assuming that script is running in root directory ?
Could you check home directory.
also you can redirect as below;
nohup /usr/hp/ism/jboss-3.2.8.SP1/bin/run.sh &> /tmp/nohup.out
man nohup ;
If standard input is a terminal, redirect it from /dev/null. If
standard output is a terminal, append output to 'nohup.out' if
possible, '$HOME/nohup.out' otherwise. If standard error is a
terminal, redirect it to standard
output. To save output to FILE, use 'nohup COMMAND > FILE'.
Running a python code using nohup and & the nohub.out was in the same directory as the command was run from
pwd output:
/home/dv/project7
command run:
nohup python3 /home/dv/project7/test_code_v3.1.py &
ls -l output:
test_code_v3.1.py
nohup.out
I think a better way is so that your program outputs to your own error log file vs. stdout thgerefore to nohub.out
I am using obsidian scheduler for scheduling various jobs written on a linux box. And trying to call shell scripts with a nohup command like
UPDATE 1:
nohup ./script.sh > output.txt &
UPDATE 2
This is the error when i use nohup.
nohup: failed to run command â./test.sh &>./load.log &â: No such file or directory
I dont see anything writing to the output file.
And secondly how can i verify that it is using nohup command to execute the script.
Thanks
I am using the below command to run my python code as a daemon on the server.
nohup python mycode.py >> log.txt 2>&1 &
For some reason unknown to me only few lines are getting written to the file.
Thanks in advance
nohup itself writing output in nohup.out so no need to redirect output to log.txt,bydefault all output will be redirected to nohup.out
My process output some log information to the console windows. When I run it as a background process, where can I find the output logs?
Depends on the process and how you started it. If it writes to stdout (which is probable, given that the output is usually to the terminal), you can redirect the output to a file with
command > logfile &
If you also want to log error message from stderr, do
command > logfile 2> errorlogfile &
or
command > logfile 2>&1 &
to get everything in one file.
If it's a systemd service you can run journalctl -u <service-name>
You can check for latest logs by clicking **SHIFT + G **
Make sure systems is installed apt-get install systemd
