Unknown Option Flag when running with sudo

Question

Following the examples for GoAccess, which is installed on Debian via apt-get:

sudo apt-get install goaccess

The log files are owned by www-data, the adm group:

$ admin@mycomputer:~# ls -l /var/log/nginx/
ls: cannot open directory /var/log/nginx/: Permission denied
$ sudo -i
root@mycomputer:~# ls -l /var/log/nginx/
-rw-r----- 1 www-data adm   9780 Aug  1 22:11 access.log
# etc...

As the admin user I can run the basic GoAccess command succesfully using sudo:

$ sudo goaccess -f /var/log/nginx/access.log

Cool!

Without sudo (or if I run it as root, the log file is not found:

$ goaccess -f /var/log/nginx/access.log

GoAccess - version 0.6 - Oct 21 2013 23:06:19

An error has occurred
Error occured at: parser.c - parse_log - 798
Message: Error while opening the log file. Make sure it exists.

But when I run as sudo, the options/flags following the log file name are not recognized:

$ sudo goaccess -f /var/log/nginx/access.log -o report.html --real-time-html 
Unknown option `-o'.
$ sudo goaccess -f /var/log/nginx/access.log --no-csv-summary -o report.csv
Unknown option `--'.

I'm confident the bug is in my workflow. Can someone spin me in the right direction?

Answer 1

The --no-csv-summary flag was added in version 0.9, from March 2015. Your version is 0.6. The current version as of August 2016 is 1.0.2.

You may need to add the official GoAccess debian repository:

$ echo "deb http://deb.goaccess.io/ $(lsb_release -cs) main" | sudo tee -a /etc/apt/sources.list.d/goaccess.list 
$ wget -O - https://deb.goaccess.io/gnugpg.key | sudo apt-key add -
$ sudo apt-get update 
$ sudo apt-get install goaccess

Or build from source, for which you can find a guide here.
