unable to start a service in systemd

Question

I am trying to start a service in ubuntu 16.04. And wrote this .service file

[Unit]
Description=Executing during boot

[Service]
Type=forking
ExecStart=/home/lokesh/Documents/script.sh
TimeoutSec=30
Restart=on-failure
RestartSec=30
StartLimitInterval=350
StartLimitBurst=10

[Install]
WantedBy=multi-user.target
Alias=startUp.service

Added this service file to /etc/systemd/system/ And this is script file, so basically I am trying to execute a simple operation to write to a file

#!/bin/sh
echo "I'm feeling good" >> txt
echo "how are you" >> txt 

Before restart I tested the script file it is working and producing a txt file with some texts in it. And then followed these steps:

chmod u+x /path/to/script/script.sh
sudo systemctl start startUp.service
sudo systemctl stop startUp.service
sudo systemctl enable startUp.service

But after reboot I am supposed to get a new file named txt with few texts. But I am unable to get the output. Is it happening because service is not started or else there is something wrong with service file or script file ?

Regards

Answer 1

Any program, script or service that starts during boot time only has a limited environment. Therefor you must always use full path names.
In this case you need to enter the full path where txt needs to be created. So as per your example:

/home/lokesh/Documents/txt

I would not be surprised if the file txt is to be found in /root, assuming your service does start
