In some of my servers there is this strange line at the end of /etc/passwd/ consisting of just:

+::::::

Does anyone knows what it means?

I searched the net but only found the same, unanswered question by one Jim from 2012:

Anyone know what this means in Linux SLES 11 and can it be removed

(see https://www.cyberciti.biz/faq/understanding-etcpasswd-file-format/).

Servers in question run SLES 12, the other Ubuntu bionic.

I have a script that runs on the host and creates/starts/stops a docker container. I'd like the script to change the password of the root user within the container.

Since the container is an ssh server, I tried: sshpass -p 'OLDPASS' ssh root@<container-IP> 'echo -e "NEWPASS\nNEWPASS" | passwd root'

but it doesn't work. Before going ahead and spending more time debugging it, I'd like to know if there's a smarter way to do it.

I understand that the proper "docker way" is to make a script that is run by the Dockerfile, which pulls the password from a shared volume and sets it as the root password. This sounds complicated, but I know how to do it and works well for another docker image I use. But I don't want to do it for this one.

I just need a command that uses Docker or ssh to change a user's password non-interactively.

bash ssh docker passwd

I was recently asked to modify the GECOS field in the passwd file for a certain user so that it will contain his name with his original accented characters. My first was reaction was "sure, why not?" but then I started getting paranoid that there will surely be a *nix utility that will fail to parse the passwd file because of UTF-8 characters.

So my question is, have you ever ran into any problems using UTF-8 in the passwd file? Or do you know of any?

My locale is set to UTF-8 on all boxes. ( $LANG=en_US.UTF-8 )

Thanks!
