SSSD Override Shell

If you have SSSD running and the default shell is ksh even with the default shell set to bash.

Here’s the fix to override the default shell in /etc/sssd/sssd.conf. Add override_shell.

default_shell = /bin/bash
override_shell = /bin/bash

To check which shell you are using.

echo $SHELL
/bin/bash

GCP Cloud Shell Vim Settings

I had an issue with using the backspace in Vim in GCP’s Cloud Shell. Every time I’m in the insert mode and I want to edit using backspace, it doesn’t delete the characters. It shows these characters “^?” instead. Well, it turned out to be a backspace setting that you can set within .vimrc. So, here’s my working setup.

colo desert
syntax on
set backspace=indent,eol,start
  • The first line uses the desert theme.
  • The second line turns on syntax highlighting. It’s on by default.
  • The third line fixes the backspace issue I mentioned above.

Linux Useradd

Here’s the command to add a Linux user.

useradd -m -s $(which bash) -G sudo ulysses

-m creates a home directory. -s selects a shell. -G adds user to a sudo group.
