Shell script is throwing error

[rahul0698]

can you please check #line76 in the shell script I think there is some issue with the command. When I ran the script file it is showing error with the command. Attaching the error log and also an error in starting adbd.service(adbd.service is running actively in the background). unit not found but adbd.service is there in the /etc/systemd/system folder.

nginx service is running in the background as default after install nginx. Do I need to modify some files or do an additional thing before running the script to make it work?
