Changing the login shell of a user with syno* tools?

[miguno]

Do you happen to know if any of the syno* command line tools allow you to change the login shell of a user?

sh-4.3# synouser --get wuseman
User Name   : [wuseman]
User Type   : [AUTH_LOCAL]
User uid    : [1026]
Primary gid : [100]
Fullname    : []
User Dir    : [/var/services/homes/wuseman]
User Shell  : [/bin/sh]                        <===== HERE
Expired     : [false]
User Mail   : []
Alloc Size  : [82]
Member Of   : [2]
(100) users
(101) administrators

For what it's worth, manually fiddling with /etc/passwd (like one would on a normal, non-Synology OS) doesn't work with the latest DSM versions, at least from what I can tell. And standard tools like chsh don't exist on the Synology NAS.

any solution to this?

Any solution? Changing the /etc/passwd makes it impossible to ssh so looking for "The Syno Way"...

@ThomasDalla - just found this out the hard way. What was your solution to changing the /etc/passwd file back? Syno make it quite hard to edit these sort of files from their desktop!

@jt196 I was able to reset the /etc/passwd file by creating a new test user through DSM Control Panel > User & Group, which fixed ssh access for me.

FYI this worked for me. Which was to:

1. Create a file named .profile in the user folder
2. Append the following text:

if [[ -x /usr/local/bin/zsh ]]; then
  export SHELL=/usr/local/bin/zsh
  exec /usr/local/bin/zsh
fi

3. Log out, log in and everything should work ok. All the files are in the user home as well, so easily accessible.

Thanks for sharing this info, @jt196. The link you mentioned above about installing Oh My ZSH on Synology is broken, however. The working one is: https://3os.org/infrastructure/synology/Install-oh-my-zsh/
