[Unit]
Description=PyFilebrowser Service
After=network-online.target

[Service]
Type=simple
WorkingDirectory=/home/vicky/pyfilebrowser
ExecStart=/home/vicky/pyfilebrowser/venv/bin/python /home/vicky/pyfilebrowser/temp.py
User=vicky
Group=vicky
Environment="PATH=/home/vicky/pyfilebrowser/venv/bin:$PATH"
StandardOutput=append:/var/log/pyfilebrowser/output.log
StandardError=append:/var/log/pyfilebrowser/error.log

[Install]
WantedBy=multi-user.target

User and Group are not required if the permissions to the files are changed to www-data
Since that involves changing permissions even for modules within venv, it is simpler to run as user
