What do the `--disabled-login` and `--gecos` options of `adduser` command stand for?
Running Ubuntu 12.04, I setup a private git server and created a group called git some time ago. Now I am following a guide to install gitlab and when it came to adding a user to the git group and create it, I saw that I already had it.
The command is this:
sudo adduser --disabled-login --gecos 'GitLab' git
taken from Gitlab installation Tutorial.
I would like to understand that command correctly. For me I thought I add a user to a group like this:
adduser user group
So what do --disabled-login and --gecos stand for?
command-line adduser

It's all written in the manual page!
You don't need to install something, to search on google or to have an internet connection. Just open your terminal and first of all you must to run the following command:
man adduser
to open the manual page for adduser command.
Then, in that manual page type: /--disabled-login followed by Enter then press repetitively n to find all occurrences containing --disabled-login. Do the same for --gecos.
With a little bit of luck you will find out that:
--disabled-login
Do not run passwd to set the password. The user won't be able
to use her account until the password is set.
and:
--gecos GECOS
Set the gecos field for the new entry generated. adduser will
not ask for finger information if this option is given.
For those wondering what gecos actually is, wikipedia defines it as follows:
The gecos field, or GECOS field is an entry in the /etc/passwd file on Unix, and similar operating systems. It is typically used to record general information about the account or its user(s) such as their real name and phone number.

Actually GECOS is really badly explained in the manpage. It's the part where it asks for real name, phone etc. en.wikipedia.org/wiki/Gecos_field

This answers does not explain what gecos is. I came here looking for this info too. Nor does it explain that --disabled-login does not actually disable login as the man implies. it just disables login via password. It is usually used when you set the certificate for cert based ssh login.

I actually used GCOS systems way back in the day, so seeing this field brings back memories of being a carefree if very geeky high school senior. :-)
